XJ05RADIAL PISTON MOTOR You are at the centre of everything we do

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, service...

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 with...

PRODUCT CAM FRONT MODULE PORT MODULE REAR BRAKE OPTIONS SPECIALS DESIGN Do not run in brake, wearing the plates will reduce the static capacity. Dynamic use of the brake is not recommended and should only be used in emergency situations. The disc pack should be replaced after ten dynamic uses. Times may vary depending on fluid viscosity and valves used. During low temperature applications, flushing the brake housing is recommended to maintain a constant oil viscosity. All data is based on ISO46 fluid at 50°C/122°F. If a different fluid will be used, please consult Rotary Power....

PRODUCT CAM FRONT MODULE PORT MODULE REAR BRAKE OPTIONS SPECIALS DESIGN The XJ motor code defines the starting direction of the motor. This is selected by the customer to best suit their application needs. The starting direction is based on flow being supplied to port A. A single speed motor can have its starting direction reversed by supplying flow to port B. In two speed motors, pressurising port A is preferred as this prevents the motor from recirculating high pressure oil when shifted into second displacement. It is important to select the correct starting direction of a...

This sensor provides a square wave signal used to calculate motor speed. Note that the sensor target is constructed using a modified XJ05 rotor. Integrating the sensor target into the rotor allows the envelope of the motor to remain consistent with standard sizes.
