Rotary Power specialises in the design, development and manufacture of hydraulic motors and pumps. With a history dating back over 50 years, we understand the exacting and demanding requirements of today’s hydraulic applications. Operating from 18,000 sq. m. of purpose built manufacturing facilities, based in the North East of England and Bangalore, India, we continue to invest in the latest CNC machinery, automation and testing facilities. We have a clear focus on continuous improvement in lean cellular manufacturing. These facilities, alongside our European and US operations, offer sales,...

The XJ range of hydraulic motors offer displacements from 260 to 5,010 cc/rev. The XJ05 is the smallest of the range with displacements from 260 to 565 cc/rev, complemented by the larger XJ20 and XJ40 motors extending the displacement range to 2,505 and 5,010 cc/rev. The XJ motor has a range of features and options designed to suit your specific application: • • • • • • • • Radial piston, multi-stroke operation Modular design Two speed options Parking brake options Freewheel capability Multiple mounting arrangements 350 bar continuous pressure Fast delivery options The motor is designed...

FIRST DISPLACEMENT Displacement option SECOND DISPLACEMENT Nominal displacement (cc/rev) *Maximum values should only be applied for a small portion of the duty cycle. Weight of motor without oil Sizes are listed in mm, inches shown in brackets 4

QUICK SELECTION DIAGRAM Based on your torque and speed requirements, the diagram below can be used to help determine which cam size best suits your application. Shown for both maximum displacement (1D) and minimum displacement (2D), the diagram outlines the limits of the motor based on its continuous power rating. 50 60 70 80 Maximum Available Speed (rpm) Maximum Available Torque (lbf.ft) Maximum Available Torque (Nm)
