whitedriveproducts LIGHT DUTY Hydraulic Motor SERIES 255 256 - WR

For Light Duty Applications The WR Series motor incorporates the latest advances for smooth performance, efficiency and durability. It features an optimized Roller Stator® geometry with seven preci- sion rollers to eliminate sliding friction and provide rolling contact between the rotor and stator. This increases motor efficiency. A three-zone spool valve, integral check valves and a provision for a case drain reduce pressure on internal seals to improve product life. A wide variety of mounting, shaft, motor displacement and porting options are available to meet all application needs. FEATURES...

white drive pro ducts Light Duty Hydraulic Motor TECHNICAL INFORMATION ALLOWABLE SHAFT LOAD / BEARING CURVE The bearing curve below represents the side load capacity of the motor at the centerline of the key for various motor speeds. Operating conditions within the shaded area will maintain acceptable oil film lubrication with recommended fluids. Operating conditions outside the shaded area are susceptible to motor failure due to oil starvation and/or excessive heat generation. Fluids with low lubricity or low viscosity may require the maximum load and speed rat- ings to be derated to provide...
