Norton 66261080535 Reducing Bushing 5 to 3 Inch Arbor

Product Description

The NORTON 66261080535 is a reducing bushing designed to adapt the arbor hole of convolute deburring and flap wheels from a 5 inch bore down to a 3 inch arbor size. This hardware accessory allows shops and field technicians to mount larger-diameter abrasive wheels onto spindles with a smaller arbor without replacing the wheel or the machine. It is a direct-fit solution used in metal fabrication, maintenance, and finishing operations where wheel-to-arbor compatibility is required. Installation is straightforward and is typically performed by machinists, maintenance technicians, or abrasives specialists working with bench or pedestal grinders and deburring machines.

This reducing bushing is suited for use with convolute deburring wheels and flap wheels with a minimum wheel diameter of 10 inches. It is commonly installed in production and job-shop environments where abrasive wheel inventory includes larger-bore wheels that must be fitted to standard spindle sizes. The bushing seats into the wheel bore and reduces the effective arbor opening, enabling proper wheel mounting and centering on compatible equipment.

Key Features

• Reduces arbor bore from 5 inches to 3 inches for compatible wheel mounting
• Designed for use with convolute deburring and flap wheels 10 inches diameter and larger
• Sold individually as a single-piece hardware accessory
• Enables reuse of larger-bore abrasive wheels on smaller-arbor machines

Compatibility

Designed for use with convolute deburring wheels and flap wheels with a minimum wheel diameter of 10 inches and a 5 inch arbor bore, reducing to a 3 inch arbor size. Specific wheel and machine compatibility should be confirmed against wheel bore and spindle specifications before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel mounting procedures. Always power down and lock out the machine before mounting or removing any abrasive wheel or bushing. Confirm that the bushing seats flush and that the wheel is properly flanged and torqued per the machine and wheel manufacturer guidelines. Follow ANSI B7.1 standards for safe mounting of abrasive wheels.
