Ingersoll 311a-53 Rotor

Product Description

The INGERSOLL 311a-53 is a replacement rotor designed for use in Ingersoll pneumatic power tools. The rotor is a core rotating component inside the tool motor assembly, converting compressed air energy into the mechanical rotation that drives the output spindle. Licensed technicians and professional tool repair specialists install this part during motor rebuilds or when a worn rotor causes loss of power, excessive vibration, or inconsistent speed. Sourcing an OEM-style replacement rotor ensures the tool returns to factory-rated performance after service.

This rotor is intended for use in pneumatic tool repair and rebuild applications. It fits within the internal motor housing of compatible Ingersoll air-powered tools, making it relevant for tool repair shops, industrial maintenance teams, and professional contractors who rely on pneumatic impact wrenches, ratchets, or similar air tools for daily use. Consult the tool service manual to confirm this rotor is the correct replacement for the specific model being serviced.
