Why Choose Our E-Series In-line Planetary Gearbox? — Our E-Series is designed as a genuine dimensional and performance replacement for the Brevini E / ED / ET / EQ / EM / EC / SL series and the Bonfiglioli 300 Series inline planetary range — the two most widely specified industrial planetary gearbox families in global circulation. Every critical parameter is matched: housing bolt pattern, output shaft geometry, motor flange standard, torque rating, and gear ratio. The modular architecture supports foot mounting, flange mounting, solid keyed shaft, splined shaft, hollow shaft with shrink disc, and full brake integration — enabling bolt-on replacement without machine modification. Ground gears throughout, 96–98% per-stage efficiency, and a full factory acceptance test report with every unit.
E-Series In-line Planetary Gearbox — Product Overview
The E-Series In-line Planetary Gearbox is a fully modular coaxial planetary gear reducer built for the widest possible range of industrial, mobile, and agricultural drive applications. "E-Series" encompasses the engineering family that replaces the Brevini E / ED / ET / EQ / EM / EC / SL industrial planetary range — nine harmonically scaled sizes covering 1,200 N·m to 450,000 N·m — as well as the equivalent Bonfiglioli 300 Series inline models. The defining characteristic of this family is its modularity: a common planetary gear architecture that can be combined with any of five output configurations, four standard input interfaces, optional integrated braking, and up to four reduction stages (six on request), all within the same housing family. This modularity is what has made the Brevini E and Bonfiglioli 300 Series the dominant specification in European-engineered industrial machinery for the past three decades — and it is what makes our E-Series the most versatile replacement option available.
Our E-Series in-line planetary gearbox is engineered to match all critical OEM dimensions — housing bolt pattern, output shaft diameter and keyway or spline geometry, motor flange pilot diameter, and centre-distance — based on dimensional drawings taken directly from Brevini and Bonfiglioli OEM installation manuals. This is not a generic "compatible" product: each cross-reference in our database is verified before it is confirmed to a customer. The result is a confirmed bolt-on replacement that eliminates re-engineering, eliminates adaptor plates, and reduces downtime to the minimum required for physical swap-out.
The E-Series covers output torque from 1,000 N·m to 450,000 N·m in the standard range, with gear ratios from 3.4:1 to 9,000:1 available across 1- to 4-stage configurations. Transmission efficiency per stage is 96–98% — consistent with the original Brevini and Bonfiglioli specifications. All models carry ISO 9001:2015 certification and CE marking, and every unit is supplied with a full factory acceptance test report run at rated torque and speed.

Core Advantages of the E-Series In-line Planetary Gearbox
Eight engineering and commercial reasons why procurement and maintenance engineers choose our E-Series as their Brevini and Bonfiglioli 300 Series replacement:
● Confirmed Dimensional Cross-Reference
Every OEM cross-reference in our database is verified against dimensional drawings taken from Brevini and Bonfiglioli OEM installation manuals — not estimated from published torque data. Housing bolt pattern, output shaft diameter, keyway dimensions, and motor flange pilot diameter are all confirmed before a cross-reference is issued to a customer.
● Full Modular Configuration Range
Five output configurations, five input interface options, three brake types (hydraulic, DC electric, AC electric), 1–4 reduction stages, and a choice of solid keyed shaft, splined shaft, hollow shaft, or flanged output — all within the same housing family. This mirrors the full Brevini E and Bonfiglioli 300 series modularity, ensuring that even unusual factory configurations can be replicated without bespoke tooling.
● Profile-Ground Gear Sets
All sun gears, planet gears, and ring gears are carburised, hardened to 58–62 HRC, and profile-ground to DIN/ISO Class 6 accuracy. This matches the gear quality level specified in the Brevini E and Bonfiglioli 300 production standards, and is not substituted with lower-accuracy hobbed gears to reduce cost.
● 96–98% Per-Stage Efficiency
Rolling-contact planetary gearing delivers 96–98% efficiency per reduction stage — consistent with the OEM specifications it replaces. In continuous-duty applications running thousands of hours per year, the efficiency advantage over worm-gear alternatives directly reduces operating cost.
● Widest Ratio Range: 3.4:1 to 9,000:1
The E-Series covers gear ratios from 3.4:1 (single stage, high-speed output) to 9,000:1 (four stages, ultra-low speed). This is the widest single-family ratio range available in an inline planetary gearbox of this torque class — matching the full Bonfiglioli 300 and Brevini E Series ratio coverage without requiring product family changes.
● Fast Availability — Stock & Short Lead Times
The most frequently ordered Brevini ED / ET / EQ / EM / EC models and Bonfiglioli 306 / 307 / 309 / 310 replacements are held in partial-build stock — machined housing and completed gear sets — allowing final assembly and FAT completion within 7–20 days of order. This is significantly faster than original Brevini or Bonfiglioli lead times for replacement units.
● Four-Stage Reduction Standard
Brevini introduced overhung planet pins and four-planet-per-stage gear sets as standard features of the E Series to improve load distribution and bearing life. Our E-Series replicates this design — each stage uses four planet gears (not the three-planet minimum) to share load across more contact points, reducing peak stress and extending gear and bearing life at equivalent duty cycles.
● 100% Factory Acceptance Test
Every E-Series unit is run at rated torque and speed for a minimum of two hours on our loaded test benches. Oil temperature, housing temperature, vibration, and seal integrity are recorded and reported. A full test report is supplied with every shipment — providing the documentation required for quality-assured maintenance programmes.
How the E-Series In-line Planetary Gearbox Works
The E-Series uses a coaxial multi-stage planetary gear arrangement. The five steps below describe the complete power flow through a standard two-stage configuration:
Motor Input
The hydraulic or electric motor drives the first-stage sun gear — the smallest element — at rated speed. At this stage, speed is high and torque is low. The input flange matches the motor mounting standard exactly, eliminating adaptor plates in OEM replacement installations.
Four-Planet Load Sharing
Four planet gears (a key E-Series design feature, matching the Brevini E specification) mesh simultaneously with the sun gear and the fixed ring gear. Each planet carries one-quarter of the total torque — distributing load across all four contact points and enabling the compact housing to transmit output torques many times what a single-mesh gear stage of the same diameter could achieve.
First-Stage Reduction
The planet carrier — supported on overhung pins as in the original Brevini E design — outputs at reduced speed and amplified torque. Speed drops by the stage ratio; torque increases by the same factor. The coaxial output direction is maintained, preserving the straight-line drivetrain.
Additional Stages
For the high reduction ratios of up to 9,000:1 required in industrial applications, the E-Series adds two, three, or four reduction stages — each with its own sun gear, four planet gears, and planet carrier. Every additional stage multiplies output torque while adding only modest axial length, keeping the overall unit compact.
Coaxial Output
The final-stage carrier drives the output shaft or flange — fully coaxial with the motor input. High torque at low speed is delivered through the selected output configuration (keyed shaft, splined shaft, hollow shaft, or flange) into the driven equipment — with the same interface geometry as the original OEM gearbox it replaces.
E-Series Application Scenarios
The E-Series modular architecture and wide ratio range make it the standard choice for the same applications in which the Brevini E / ED / ET / EQ series and Bonfiglioli 300 Series are the existing specification:
Industrial Conveyor & Bucket Elevator Drives
The E-Series is the standard drive for heavy belt conveyors, chain conveyors, and bucket elevators in mining, aggregates, ports, and food processing. The modular foot or flange mounting and hollow shaft shrink-disc output make it simple to replace an existing Bonfiglioli 306–313 or Brevini ED/ET unit without modifying the driven shaft or support structure.
Industrial Hoist & Winch Drives
Overhead crane hoists, maintenance hoists, and industrial winches require a reliable inline planetary gearbox with an integrated fail-safe brake. The E-Series integrated brake option — hydraulic or electric release, spring-applied — meets the load-holding requirements of EN 14492-2 and replaces the brake-equipped Brevini EC and Bonfiglioli 300 brake variants on a direct-fit basis.
Construction & Mining Machinery
Concrete mixer drives, shotcrete machine drives, drill rig auxiliary drives, and mining equipment ancillary drives. These applications require the E-Series' high shock-load tolerance (provided by the carburised, ground planetary gear sets) and its compatibility with hydraulic orbit motors — a common input in mobile construction equipment.
Agricultural Machinery
TMR feed mixer drives, grain auger drives, irrigation pump drives, and harvest equipment auxiliary drives. The wide ratio range (3.4:1 to 9,000:1) covers both high-speed auger drives and the ultra-slow feed rates of precision dispensing equipment without requiring a product family change. Electric and hydraulic motor input configurations are available for all standard agricultural drive interfaces.
Marine & Offshore Auxiliary Drives
Deck machinery auxiliary drives, anchor windlass secondary reductions, and davit drives. The IP67 sealing option and marine coating system (C5-M rated) make the E-Series suitable for washdown-duty and exposed marine environments. BV, ABS, and Lloyd's certification is available on request for class-society applications.
Rotary Tables & Indexing Drives
Industrial rotary tables, automated assembly carousel drives, and precision indexing mechanisms. The flanged output configuration and high gear ratio accuracy (ground DIN/ISO Class 6 gears) of the E-Series make it suitable for repeatable positioning applications where the original Bonfiglioli 303–307 or Brevini EM/ED series is the existing specification.
E-Series In-line Planetary Gearbox — Frequently Asked Questions
Technical and procurement questions regularly received by our engineering team from customers sourcing Brevini and Bonfiglioli 300 Series replacements:
Q 01
Is the E-Series a genuine bolt-on replacement for Brevini ED / ET / EQ / EM / EC models?
Yes — for all Brevini ED, ET, EQ, EM, EC, and SL models in our cross-reference database, we provide confirmed dimensional drawings before order confirmation. Housing bolt pattern, output shaft interface (diameter, keyway width and depth, or spline specification), and motor flange pilot diameter are all verified against OEM installation drawings. Submit the Brevini model number — for example, ED2065, ET3150, EQ4090, EC3045, or SL600 — and we return a confirmed cross-reference within 48 hours.
Q 02
Can the E-Series replace Bonfiglioli 300 Series models such as 306L, 309L, or 313L?
Yes. Our E-Series cross-reference database covers the full Bonfiglioli 300 Series inline range from model 300L through 321L, including all reduction stage suffixes (L1 single-stage through L4 four-stage). The Bonfiglioli 306L, 307L, 309L, 310L, 311L, and 313L are among the most frequently requested — provide the full model number including the ratio code and output shaft type suffix, and we confirm the equivalent E-Series model with dimensional drawing within 48 hours.
Q 03
What is the difference between the Brevini E Series (E030–E225) and the Brevini ED / ET / EQ series?
The Brevini E Series (E030 through E225) is the current generation of Brevini's modular industrial planetary range, covering nine harmonically scaled sizes with torque from 1,200 N·m (E030) to 26,000 N·m (E225). The ED, ET, EQ, EM, EC, and SL series are the extended range beyond 26,000 N·m — covering up to 450,000 N·m — using the same modular design principles but with larger housing frames and higher-capacity gear sets. Our E-Series covers both families across their full torque range in a single product line.
Q 04
My existing gearbox has an integrated hydraulic brake — can you supply a direct replacement with the same brake?
Yes. An integrated hydraulically-released parking brake is a standard factory option on all E-Series models. The brake is spring-applied (fail-safe) and hydraulically released — the same configuration as the Brevini EC and Bonfiglioli 300 Series brake variants. DC and AC electric brake options are also available. Brake torque is rated to hold the full nominal output torque at any gear ratio. Specify the brake release type (hydraulic, DC, or AC) and the required brake release pressure or voltage when placing the order.
Q 05
Can the E-Series be used with an IEC electric motor as well as a hydraulic motor?
Yes. The E-Series input configuration is fully modular — IEC B5 and B14 electric motor adaptors, NEMA adaptor plates, flanged axial-piston hydraulic motor interfaces (SAE A through SAE D), hydraulic orbit motor flanges, and solid input shafts are all standard factory options. The same gearbox housing and gear set can accept any of these input types simply by changing the input adaptor — no modification to the output side. This is the same modularity principle as the original Brevini and Bonfiglioli designs.
Q 06
Can you supply a custom gear ratio not listed in the standard range?
Yes. The E-Series modular gear set architecture allows non-standard ratios to be achieved by selecting alternative sun gear, planet gear, and ring gear tooth counts from the modular gear library — without requiring entirely new tooling. Custom ratios are available across the full 1,000 N·m to 450,000 N·m torque range. Submit your required input speed, output speed, and output torque, and our engineers will calculate the achievable ratio options and confirm pricing and lead time — typically 30–60 days for custom ratio configurations.
Q 07
Does the E-Series also replace the Dinamic Oil RE and GB series?
Yes. The Dinamic Oil RE series (RE110 through RE8000) and GB series (GB12010 through GB205000) are inline planetary gear reducers in the same torque class as the E-Series, and are fully covered in our cross-reference database. The RE and GB series use the same coaxial architecture and similar motor flange standards as Brevini and Bonfiglioli — making dimensional cross-referencing straightforward. Submit the Dinamic Oil model number and we return a confirmed cross-reference drawing within 48 hours.
Q 08
What quality documentation is supplied with each E-Series gearbox?
Every E-Series unit is supplied with: (1) a full factory acceptance test (FAT) report recording oil temperature, housing surface temperature, vibration, noise level, and seal integrity — measured during a minimum 2-hour loaded run at rated torque and speed; (2) EN 10204 3.1 material test certificates for all alloy steel forgings; (3) heat treatment batch records; (4) gear tooth profile and lead measurement records (for units above 30,000 N·m rated torque); and (5) CE Declaration of Conformity.
