Built for milling, routing, deburring, and precision material removal, the Ingersoll Rand 7801-4B Non-Reversible Milling Motor delivers 0.85 HP with a free speed of 4,600 RPM for applications that require increased torque at lower operating speeds. Featuring forward rotation and a single gear reduction, this pneumatic milling motor develops 4.00 ft-lbs of stall torque, providing the controlled power needed for heavier milling operations and demanding material removal tasks. Its air-powered design allows the motor to operate continuously in industrial environments while offering smooth speed control through regulated compressed air.
As part of Ingersoll Rand's milling motor lineup, the 7801-4B is designed for fixture-mounted machinery, automated production equipment, and dedicated milling applications. The single gear reduction optimizes torque output while maintaining efficient operating speed, making this motor well suited for metalworking, fabrication, manufacturing, and production processes where dependable pneumatic power is preferred over electric drive systems.
