Product Introduction
ATUS LR/KR Series orbital hydraulic motor is a low-speed high-torque geroler motor with spool valve design. It converts hydraulic energy into stable rotary output, delivers smooth rotation even at ultra-low speed. Compact structure and standardized interfaces make it a direct replacement for mainstream orbital motors for medium-duty mobile and industrial equipment. Multiple displacement options and optional built-in check valves are available for diverse drive schemes.

Features
Spool valve geroler rotor-stator assembly, stable low-speed performance, low pulsation
Compact body with high torque density, small installation footprint
Reinforced bearing configuration to bear higher radial and axial shaft loads
Integrated built-in check valves optional, simplify external circuit layout
Multiple displacement sizes cover wide torque range
Bidirectional rotation available for forward/reverse drive
Optimized three-pressure-zone design reduces case pressure and extends seal service life
Good starting efficiency, stable output under light or heavy load
Low noise during continuous operation
High interchangeability for market mainstream models
Advantages
Cost-effective direct replacement, short lead time
Strong contamination resistance, suitable for harsh working environment
Smooth rotation without creeping at low RPM
Modular structure, easy to disassemble and maintain on site
Flexible configuration of shaft type, port position and auxiliary functions
Stable volumetric efficiency for long continuous duty cycle
Mounting Style
Standard 2-bolt, 4-bolt SAE flange mounting options; multiple shaft selections including keyed shaft and splined shaft.
The mounting surface shall be flat and fully fitted.
Keep shaft coupling concentric to avoid extra radial load.
Installation position can be horizontal or vertical; drain port wiring shall follow the manual to prevent housing overpressure.
Application Range
Suitable for sweepers, road rollers, harvesters, feeders, conveyor drives, small winches, lawn machines, forestry machinery and other mobile equipment low-speed drive systems.
