Norton 66261080531 Reducing Bushing for 8 Inch Deburring Wheels

Product Description

The NORTON 66261080531 is a reducing bushing designed to adapt the center hole of 8-inch diameter flap convolute deburring wheels from a 3-inch bore down to a 1-inch arbor size. This hardware accessory is a direct-fit component used when mounting larger-bore abrasive wheels onto smaller arbor shafts, eliminating the need for a dedicated replacement wheel when the spindle size does not match. Metal fabricators, tool room technicians, and maintenance professionals routinely use reducing bushings like this to maximize wheel inventory flexibility and reduce downtime when swapping abrasive wheels across multiple machines.

This bushing is specifically sized for 8-inch diameter flap convolute deburring wheels with a 3-inch wheel hole, reducing to a 1-inch arbor. Flap convolute wheels are commonly found in metal finishing, deburring, and surface conditioning applications in both production shop and maintenance environments. The bushing allows a single wheel style to be run on grinders or finishing machines with differing spindle diameters, making it a practical stocking item for shops running mixed equipment.

Key Features

• Reduces wheel bore from 3 inches down to 1-inch arbor size
• Designed specifically for 8-inch diameter flap convolute deburring wheels
• Hardware-type reducing bushing for secure wheel mounting
• Sold individually, allowing single-unit replacement

Compatibility

Compatible with 8-inch diameter flap convolute deburring wheels that have a 3-inch wheel hole and require adaptation to a 1-inch arbor spindle.

Installation Notes

Installation should be performed by a qualified technician following the grinder or finishing machine manufacturer's mounting instructions. Always power down and lock out the machine before removing or installing any wheel or bushing. Verify that the bushing seats fully and flush within the wheel bore before securing the flange nut, and inspect the wheel for cracks or damage prior to mounting. Follow applicable ANSI B7.1 safety standards for abrasive wheel mounting.
