Ingersoll Rand M007RVR021AR4 Multi-Vane Reversible Air Motor is designed to deliver dependable pneumatic rotary power for industrial equipment requiring bidirectional operation with higher torque at controlled operating speeds. Featuring a multi-vane design and planetary gearing, this air motor develops 0.64 HP while operating at a free speed of 855 RPM. Its reversible configuration enables both clockwise and counterclockwise shaft rotation, making it ideal for OEM machinery, automated production equipment, material handling systems, positioning devices, and industrial applications requiring reliable directional control.
The M007RVR021AR4 develops a 9.2 lb-ft starting torque, providing excellent load-starting capability for demanding industrial applications, and delivers a 12.2 lb-ft stall torque, representing the maximum torque generated when the output shaft is prevented from rotating. The planetary gear arrangement efficiently multiplies output torque while maintaining a compact motor assembly suitable for installations where performance and mounting space are both important considerations.
