3M 7100071830 Double Sealed Bearing 12x28x8mm Ros

Product Description

The 3M 7100071830 is a double-sealed replacement bearing designed for use in 3M Elite Random Orbital Sanders. Measuring 12 millimeters inner diameter, 28 millimeters outer diameter, and 8 millimeters wide, this bearing features two integrated seals that block contamination from entering the bearing race during operation. It is a direct OEM-style replacement part intended to restore proper spindle function and extend tool service life. Installation is typically performed by tool repair technicians or experienced trade professionals during scheduled maintenance or unplanned downtime repair.

This bearing is used in orbital sander servicing applications where worn or failed bearings cause vibration, noise, or loss of pad control. It is suited for shop environments, fleet tool maintenance programs, and field repair kits where keeping sanders running at full capacity reduces job-site downtime. The double-seal design makes it appropriate for environments where dust and debris are prevalent, such as woodworking, metalworking, and surface preparation settings.

Installation Notes

Bearing replacement should be performed by a qualified tool repair technician familiar with orbital sander disassembly procedures. Disconnect and de-energize the tool completely before beginning any service work. Use appropriate bearing press or insertion tools to seat the bearing without applying force to the bearing seals or races, as impact installation can damage the seals and compromise contamination protection. Refer to the 3M service documentation for disassembly sequence and reassembly torque guidance.
