Norton 66261080533 Reducing Bushing 1 Inch Arbor

Product Description

The NORTON 66261080533 is a reducing bushing designed to adapt the arbor hole of flap convolute and deburring wheels to a smaller spindle size. It reduces the wheel bore down to a 1 inch arbor, allowing wheels with larger center holes to be mounted on smaller-diameter spindles without requiring a separate adapter. This bushing is a small but critical fit component used during wheel changes on bench grinders, angle grinders, or finishing machines. Abrasive wheel technicians and metalworking shops rely on this type of bushing to maintain proper wheel seating and minimize runout during deburring and surface finishing operations.

This reducing bushing is suited for use with flap convolute wheels and deburring wheels that have a minimum wheel diameter compatibility of 10 inches. It is commonly used in metal fabrication shops, maintenance facilities, and production finishing environments where multiple wheel sizes and spindle configurations are in use. The bushing ensures a secure, concentric fit when swapping wheel assemblies on shared or multipurpose grinder setups.

Key Features

• Reduces wheel bore to 1 inch arbor size for compatibility with smaller spindles
• Designed for use with flap convolute and deburring wheel styles
• Compatible with wheels of 10 inch minimum diameter
• Enables wheel reuse across multiple machine configurations without additional hardware
• Compact and lightweight at 2.133 pounds for easy handling during wheel changes

Compatibility

Rated for use with flap convolute and deburring wheels with a minimum wheel diameter of 10 inches. Reduces the wheel bore to a 1 inch arbor size. Specific wheel model compatibility should be verified against the wheel center hole size before installation.

Installation Notes

Installation is typically performed by a qualified grinding machine operator or abrasive products technician. Before mounting or removing any wheel, power down the grinder completely and confirm the spindle has stopped rotating. Ensure the bushing seats flush and concentrically within the wheel bore before securing the flange and nut. Follow ANSI B7.1 safety standards for the mounting and use of abrasive wheels, and inspect the wheel and bushing for cracks or damage prior to each use.
