Built for high-speed milling, material handling, and industrial drive applications, the Ingersoll Rand 7536-2-B Milling Air Motor delivers 0.25 HP with a 4,500 RPM free speed to provide dependable pneumatic power for continuous-duty operation. As an air-powered motor (using compressed air instead of electricity), it can operate continuously without overheating and safely stall under load without damaging internal components. The higher free speed makes it well suited for applications requiring rapid rotary motion, responsive performance, and reliable operation throughout demanding production cycles.
Designed for OEM machinery and industrial automation, the 7536-2-B provides smooth, controllable performance in applications where compact size and dependable pneumatic power are essential. Motor speed can be adjusted by regulating the compressed air supply, allowing operators to match performance to changing process requirements. Its pneumatic design also makes it suitable for environments where electric motors may be less desirable due to moisture, dust, or continuous-duty operating conditions.
