3M 7000118748 Replacement Rotor Orbital Sander

Product Description

The 3M 7000118748 is a machined plastic rotor designed as a direct replacement component for orbital sanders and random orbital sanders. The rotor holds 5 vanes in position to maintain consistent airflow and maximize power transfer to the sander during operation. This is an OEM-style service part intended for technicians and equipment repair professionals performing motor-section rebuilds or vane replacement on pneumatic sanding tools. Keeping the rotor in serviceable condition is essential to maintaining consistent tool speed and preventing premature wear on surrounding components.

This rotor is suited for use in pneumatic orbital and random orbital sander service applications. It is typically installed during scheduled maintenance intervals or when a tool shows signs of reduced speed, power loss, or irregular motion caused by worn or damaged vane assemblies. Repair technicians working in production environments, body shops, and woodworking facilities will encounter this part during standard tool teardowns.

Key Features

• Holds 5 vanes to support consistent airflow and full power delivery
• Machined plastic construction designed for the rotor chamber of pneumatic orbital sanders
• Direct replacement component for OEM rotor assemblies
• Sold individually for targeted component-level repair

Compatibility

Designed as an OEM-style replacement rotor for 3M orbital sanders and random orbital sanders requiring a 5-vane rotor assembly.

Installation Notes

Installation should be performed by a qualified pneumatic tool repair technician. Disconnect the tool from the air supply and depressurize the line before disassembly. Follow standard pneumatic tool teardown procedures and inspect all surrounding vane, housing, and end-plate components before reassembly. Refer to the applicable 3M tool service manual for proper assembly sequence and torque guidance.
