What Is the EP300R Right Angle Planetary Gearbox — and What Does It Do?
The EP300R series right angle planetary gearbox is a multi-stage planetary reducer combined with a spiral bevel output stage that delivers torque at exactly 90° to the input shaft. It is designed for applications where high output torque is required in a constrained envelope — and where the motor or power source cannot be positioned on the same axis as the driven component.
The series spans 16 frame sizes from EP300R through EP321R, covering output torque from 1,000 to 500,000 Nm and mechanical power up to 150 kW. Every size within the range uses the same modular planetary-plus-bevel architecture — reducing the number of unique components required and making sizing changes straightforward without a full redesign.
This right angle gear drive is also available in a high-power variant that links planetary reduction efficiency with the torque density of the bevel stage — delivering a quieter, more compact result than traditional parallel-shaft gear units at comparable ratings. It serves as a direct-fit replacement for Bonfiglioli, Brevini, Bosch Rexroth, Comer Industries, Reggiana Riduttori, Rossi, and Zollern equivalent units.

Why Engineers Choose the EP300R Right Angle Gear Drive
Every point is a verifiable specification or process commitment.
From EP300R at 1,000 Nm to EP321R at 500,000 Nm — 16 frame sizes within a single modular series. Consistent architecture simplifies documentation, spares planning, and training across your entire equipment range.
Solid keyed, splined, splined hollow, and hollow-with-shrink-disc outputs let the EP300R series integrate into almost any existing drivetrain without custom adaptor work — reducing engineering time and installation cost on replacement projects.
The spiral bevel gear set produces progressive tooth contact rather than instantaneous engagement — measurably quieter and less vibration-prone than straight-cut bevel designs at the same output torque. Critical for applications in occupied structures or noise-sensitive environments.
Flanged axial piston hydraulic motors, hydraulic orbit motors, IEC-frame electric, NEMA-frame electric, and solid shaft input — covering the full spectrum of mobile and industrial drive systems without a custom interface stage.
Dimensionally equivalent to Bonfiglioli, Brevini Riduttori, Bosch Rexroth, Comer Industries, Reggiana Riduttori, Rossi, and Zollern units. Same mounting dimensions — bolt on, no shimming, no modification.
No-load run-in followed by rated-torque full-load test on every unit. Signed test report included with shipment. Units that do not pass the test are not shipped — no exceptions.
Compatible Machine Models — 130+ Excavators and Mobile Equipment

Where the EP300R Right Angle Planetary Gearbox Is Used
The right angle output makes this series the correct choice wherever the motor axis must be perpendicular to the load — a constraint that appears across most heavy equipment categories.
Wheel drives on dumpers and site vehicles, winch drum drives on tower cranes, and track-drive final drives on pavers and rollers. The compact bevel-planetary package reduces structural load on mounting brackets versus traditional parallel-shaft alternatives.
Baler and harvester head drives, PTO-driven implement gearboxes, and cattle feed mixer wagon drives requiring 90° torque transmission from a tractor hydraulic motor to a horizontal or transverse working shaft.
Conveyor corner drives, mixer head drives, rotary table drives, and agitator drives in processing plants. The foot-and-flange output mounting options accommodate both base-plate and direct-machine-body installation without custom fabrication.
Chain conveyor drives, crusher feed screw drives, and drill rig rotation heads operating under continuous high-torque loading. The EP315R through EP321R frame sizes cover up to 500,000 Nm for the heaviest mining equipment requirements.
Frequently Asked Questions
Verified Customer Reviews
"We replaced a worn Bonfiglioli right angle drive on our aggregate conveyor corner with an EP311R3. Sent the nameplate dimensions — they confirmed the frame and ratio within a few hours. Unit arrived dimensionally identical. Bolted on, filled the oil, ran a 30-minute no-load check, and put it back into service. 2,200 hours later and we haven't touched it."
"When our Brevini right angle drive failed mid-harvest, I was ready for a three-week ordeal involving customs forms, a confused freight broker, and at least one existential crisis. Instead, the EP309R3 was quoted same-day, shipped in 5 days, and fit first try. I stood there waiting for something to go wrong. Nothing did. Extremely disappointed in the lack of drama."
Related Products & Frequently Ordered Together
Buyers who order the EP300R right angle planetary gearbox commonly need these components at the same time — either as part of a complete drivetrain build or for a full service replacement.
The inline (coaxial) version of the same modular planetary architecture. Torque range 1,000–500,000 Nm with IEC and hydraulic motor inputs. Use where inline shaft arrangement is feasible — lower unit cost and slightly higher efficiency than the right angle variant.
Flanged axial piston and orbit motors dimensioned for direct mounting on EP300R input flanges. Ordering motor and gearbox together confirms interface compatibility and eliminates the most common installation issue — mismatched flange patterns between motor and reducer.
Output shaft seals, input shaft seals, internal O-ring set, and output bearing assembly for the EP300R series. Replace during the same service visit as a gearbox overhaul or motor replacement — these components are not accessible without full disassembly.
