Norton 66261080532 Reducing Bushing 3 to 1-1/4 Inches

Product Description

The NORTON 66261080532 is a reducing bushing designed to adapt the arbor hole on 8-inch diameter flap convolute and deburring wheels. It steps the bore down from 3 inches to 1-1/4 inches, allowing wheels with a larger center hole to mount securely on smaller-arbor bench grinders or finishing machines. This hardware component is a standard accessory used by metalworkers, fabricators, and trade professionals who maintain or expand their abrasive tooling setups. Proper arbor fit is critical for safe wheel operation, and this bushing provides that fit without requiring a separate wheel purchase.

This reducing bushing is intended for use with 8-inch diameter flap convolute wheels used in deburring applications. Typical install scenarios include bench grinder setups in machine shops, maintenance facilities, and fabrication environments where operators need to run a large-bore wheel on a machine with a 1-1/4 inch arbor spindle. It is a single-piece accessory supplied individually.

Key Features

• Reduces bore from 3 inches down to 1-1/4 inches for proper arbor fit
• Compatible with 8-inch minimum diameter flap convolute and deburring wheels

Compatibility

Designed for use with 8-inch diameter flap convolute deburring wheels requiring a bore reduction from 3 inches to a 1-1/4 inch arbor size.

Installation Notes

Installation should be performed by a qualified operator familiar with bench grinder safety procedures. Always power down and disconnect the grinder from its power source before removing or installing any wheel or bushing. Confirm the bushing seats flush and the wheel guard is properly reinstalled before returning the machine to service. Follow applicable ANSI B7.1 safety standards for abrasive wheel mounting.
