Notes

Refers to basic part number only. When ordering, the number of air inlets and type of connection must be specified.

1 Dynamic torque shown, static torque approximately 25% greater. Torque in each application is dependent upon air pressure and speed.
2 Maximum rpm is dependent upon operating conditions and varies for each application. Consult factory for applications exceeding these speeds.
3 Drum contact with worn shoes.
