1. What is the OMSW Orbit Motor ?
The OMSW orbit motor is a heavy-duty low-speed high-torque geroler hydraulic motor built for mobile machinery. Equipped with reinforced tapered roller bearings, it withstands heavy radial and axial shaft loads. Its high-pressure shaft seal tolerates high back pressure without an external drain line, simplifying installation. With steady low-speed output, bi-directional rotation and rugged cast iron housing, it serves as an ideal drive component for agricultural, forestry, construction and municipal hydraulic equipment.
Reinforced tapered roller bearings support extra large radial and axial shaft loads, suitable for heavy impact working conditions.
High-pressure resistant shaft seal allows high back pressure operation, no separate drain line needed for easier mounting.
Precision geroler valve group delivers stable low-speed rotation with consistent torque and low noise, no crawling at slow speeds.
Solid cast iron housing provides excellent wear and heat resistance for long service life outdoors.
Fully reversible bi-directional rotation adapts to travel, swing and roller drive demands of various mobile machines.
High interchangeability with original imported orbital motors, offering cost-effective replacement solutions
3. What is the working pressure range of OMSW Orbit Motor ?
Continuous working pressure: up to 210 bar (3045 PSI) for long-duration operation
Intermittent peak pressure: maximum 275 bar (3988 PSI) for short-term heavy loads
4. Can OMSW Orbit Motor replace other brands?
Direct equivalent for Sauer Danfoss OMSW series original motors
It shares identical flange size, shaft specifications, displacement and pressure parameters with Danfoss OMSW, enabling plug-and-play replacement without modifying equipment piping or mounting brackets.
Interchangeable with other mainstream geroler orbit motors
It can substitute Danfoss OMS/OMSS, Eaton Char-Lynn 2000/4000 series, White WS series, Parker TG/TS series and M+S MS series motors, as long as displacement, mounting flange, output shaft and working pressure match your original unit.
Strong compatibility advantages
Same installation footprint and oil port layout as imported counterparts;
Higher load capacity reinforced tapered roller bearings for longer service life;
Matched torque and speed performance to maintain original machine working efficiency;
More cost-effective than original imported motors with reliable performance.
Note before replacement
Please confirm 4 key dimensions: motor displacement, mounting flange standard, output shaft type (key/spline), and continuous working pressure, to ensure perfect interchangeability.
6. What is the typical speed range of OMSW Orbit Motor ?
Actual running speed can be adjusted by changing the input hydraulic flow rate.
