3M 7000118726 Upper Spindle Bearing Orbital Sander

Product Description

The 3M 7000118726 is an upper spindle bearing designed as a replacement component for 3M random orbital and orbital sanders. This bearing supports the spindle assembly during sanding operations, maintaining alignment and reducing friction at the top of the spindle stack. It ships without seals or shields, which is consistent with applications where lubrication access or specific fitment tolerances are required. Installation is performed by qualified tool repair technicians or experienced tradespeople familiar with pneumatic or electric sander disassembly. Keeping spindle bearings in serviceable condition is essential for maintaining consistent orbital motion and prolonging tool life.

This upper spindle bearing is used in 3M 3-inch random orbital sanders with a 3/32-inch orbit as well as in 3M orbital sanders. It is a direct replacement component suited for depot-level tool repair or field servicing of 3M abrasive tool platforms. Technicians performing scheduled maintenance or addressing spindle play, vibration, or noise in these sanders will find this bearing a direct-fit service part. It is sold individually, making it practical for single-unit repairs without requiring a full bearing kit.

Key Features

• No-seal, no-shield design for applications requiring open bearing fitment
• Direct replacement for the upper spindle position in compatible 3M sanders
• Supports proper spindle alignment and smooth orbital motion
• Sold individually, one bearing per unit
• OEM 3M replacement part for service and repair use

Compatibility

Designed for use in 3M 3-inch random orbital sanders with a 3/32-inch orbit and 3M orbital sanders. Refer to the tool service manual or 3M parts documentation to confirm fitment for your specific model before installation.

Installation Notes

Upper spindle bearing replacement should be performed by a qualified tool repair technician familiar with sander disassembly procedures. Disconnect the tool from all air or electrical power sources before beginning any disassembly. Use appropriate bearing drivers or press tools to seat the bearing correctly — do not strike the bearing race directly with a hammer. Follow 3M service documentation for proper torque and reassembly sequence.
