3M 7010329297 Telescoping Flange Wheel Adapter 1x1x0.5 in

Product Description

The 3M 7010329297 is a telescoping flange wheel adapter designed to mount a 1-inch-bore grinding or abrasive wheel onto smaller-diameter shafts. The adapter reduces a standard 1-inch wheel arbor to accept shafts measuring 0.5 inch, 0.625 inch, 0.75 inch, or 0.875 inch in diameter. Overall dimensions are 1 inch by 1 inch by 0.5 inch. It is sold as a set and is installed by machinists, metalworkers, and maintenance technicians working with bench grinders or pedestal grinders where the shaft diameter is smaller than the wheel bore.

This adapter is suited for shop environments that run multiple grinder shaft sizes and need a single adapter solution to fit a range of equipment. The telescoping design allows one part to span four shaft sizes, reducing the need to stock multiple dedicated bushings. When installed, a set of flat or cupped washers equal to approximately one-third the wheel diameter should be used for side support to ensure proper wheel seating and lateral stability during operation.

Installation Notes

Installation should be performed by a qualified technician following applicable machinery safety standards. Disconnect and lock out power to the grinder before removing or installing any wheel or adapter.
