Norton 66261080383 Reducing Bushing 2 to 1-1/2 Inches

Product Description

The NORTON 66261080383 is a reducing bushing designed to adapt the arbor hole of 8 inches diameter flap convolute deburring wheels. It steps down from a 2 inches bore to a 1-1/2 inches arbor size, allowing installers to mount a wheel onto a smaller spindle without sourcing a different wheel. This hardware type is a small but critical fit component used in grinding and finishing operations across metalworking, fabrication, and maintenance environments. Grinding technicians and shop floor mechanics are the primary installers. Proper bushing fit ensures the wheel runs true and seated against the backing flange throughout the deburring cycle.

This bushing is intended for use with 8 inches diameter flap convolute wheels in deburring applications. Flap convolute wheels are commonly run on bench grinders and pedestal grinders in production shops, job shops, and maintenance facilities. The reducing bushing is used when the available machine spindle is 1-1/2 inches and the wheel is bored to 2 inches. It closes that gap without modification to the machine or the wheel.

Installation Notes

Power down and lock out the grinder or finishing machine before installing or removing any wheel bushing. Confirm the bushing seats fully and evenly in the wheel bore before mounting the assembly on the spindle. Follow ANSI B7.1 wheel mounting guidelines and the machine manufacturer's instructions for flange torque and guard clearance. Inspect the bushing and wheel bore for damage or debris before each installation.
