Product architecture
Two planetary gearbox systems for different duty profiles
The catalogue is organized around precision servo reducers and industrial/mobile planetary drives. Start with the machine duty, then narrow the series by ratio, output torque, interface and installation constraints.
Precision planetary gearboxes
FAB/FABR, FAD/FADR, FAL/FALR and FPG/FPGA cover inline, right-angle, pulley-adapted and compact precision layouts. Frame size, rated output torque, ratio, backlash class and motor interface drive the shortlist.
Industrial and mobile planetary drives
EP300 modular gearboxes sit alongside EP400 track, EP600 wheel and EP700 slewing drives. Their final selection depends on torque, ratio, motor type, mounting, braking where applicable, thermal duty and external loads.

Interface control
Confirm the exact drawing before machining mating parts
Family-level dimensions help establish the envelope, but the release drawing should confirm pilot diameters, bolt circles, shaft form, motor adapter, output interface, ratio and installation clearance.
- Motor model and input interface
- Continuous and peak output torque
- Required output speed or ratio
- Mounting orientation and space envelope
- Backlash or lost-motion requirement
- Radial and axial output loads
Industrial epicyclic gearing
Selection checkpoints for EP-series drives
EP300 modular planetary
Check service-adjusted torque, ratio, stage arrangement, input speed, thermal capacity, shaft loads and mounting position.
EP400 track drive
Check track interface, hydraulic motor, ratio, braking requirement, sprocket geometry and external loads.
EP600 wheel drive
Check wheel or drum flange, wheel radius, ratio, torque, driver and wheel-side bearing duty.
EP700 slewing drive
Check slew support, output pinion or spline, driver, brake or holding duty and the mating slew-ring geometry.
Manufacturing and inspection context
Machining and inspection are part of the same release path as model selection. Define which dimensions, backlash or runout conditions, mounting datums and functional checks matter to the machine so the quotation and inspection scope refer to the same acceptance target.
