11200131 - ORBITAL MOTOR RE505 540CC/REV - DANFOSS
Danfoss RE505 series orbital motor, 540 cc/rev displacement, for low flow high pressure applications up to 241 bar [3,500 psi]. Roller Stator gear set for high efficiency and long service life. Flange and shaft configuration 3823, Buna-N seals, integrated slinger seal. High displacement version of the RE505 series — maximum continuous torque for demanding direct drives on heavy mobile machinery.
Why choose the Danfoss RE505 540cc orbital motor?
- RE505 series — medium duty low flow high pressure orbital motor, displacement range 120–750 cc/rev
- 540 cc/rev displacement — among the highest in the RE505 series, maximum continuous torque for direct wheel and track drives
- Roller Stator set — roller design for reduced friction, high volumetric efficiency and superior life vs traditional gerotor motors
- Oversized slinger seals — advanced shaft seal protection from contaminants in harsh environments
- Buna-N (B) seals — compatible with standard mineral hydraulic oils
- Configuration 3823 — same flange and shaft as the 200cc model, dimensional interchangeability within the RE505 range
- Compact low-speed high-torque design — direct drive without gearboxes, reduced weight and complexity
