Ingersoll Rand 8232-4 Non-Reversible Milling Motor is designed to provide high-speed pneumatic rotary power for milling applications requiring a compact, single-direction motor configuration. This motor delivers 0.60 HP with a free speed of 2,800 RPM. Its single-gear-reduction configuration provides a defined drive arrangement for compatible milling equipment that requires controlled high-speed rotary operation.
The 8232-4 provides 4.50 ft-lbs of stall torque, which is the published torque output when the motor is prevented from rotating. As a non-reversible motor, it is intended for applications where a single direction of rotation is required. The combination of 2,800 RPM speed and 0.60 HP makes this model suitable for compatible milling equipment designed around its published operating characteristics.
