WHITE 500444002B SEAL KIT

The White 500444002B Seal Kit is a genuine roller stator seal set designed for White Hydraulics’ RE (520) series orbital hydraulic motors. It includes the seals and O-rings needed to properly reseal the motor’s roller stator assembly during a rebuild, restoring sealing integrity and helping the motor deliver consistent torque and speed without internal leakage.

The RE series is part of White’s line of low-speed, high-torque orbital gerotor motors, widely used across agricultural, construction, and general industrial equipment for functions like auger drives, conveyor drives, and other rotational applications where compact torque output matters more than raw speed. Because the roller stator sits at the heart of the motor’s gerotor mechanism, the condition of its seals directly affects volumetric efficiency — a worn seal here typically shows up as reduced torque output, slower response, or visible case leakage well before other components show signs of wear.

Rebuilding with the genuine White seal kit rather than a generic substitute ensures every seal is matched to the exact dimensions and material grade the RE (520) series was engineered around. This precision matters most at the roller stator interface, where even small sealing inconsistencies can lead to internal bypass and a noticeable drop in motor performance. Servicing the motor with the correct kit during scheduled maintenance is a cost-effective way to restore original torque output and extend the motor’s working life.
