Grier Abrasives B-TB-4 Telescoping Wheel Bushing

Product Description

The GRIER ABRASIVES B-TB-4 is a telescoping wheel bushing designed to adapt grinding wheels, wire wheels, and abrasive discs to multiple arbor bore sizes. With a 1 inch outside diameter and 15/16 inch thickness, this bushing accommodates three inner diameter configurations: 1/2 inch, 5/8 inch, and 3/4 inch. The telescoping design allows a single bushing to fit multiple spindle sizes without requiring separate adapters for each bore. It is a standard accessory installed by maintenance technicians, machinists, and industrial tradespeople when mounting abrasive wheels to bench grinders, angle grinders, or similar rotating equipment.

This bushing is suited for use in shops, maintenance facilities, and industrial settings where abrasive wheels are frequently swapped between tools with differing arbor sizes. The telescoping feature reduces the need to stock multiple fixed-bore bushings, making it a practical solution for facilities running mixed equipment. It is typically used with standard bench grinder or angle grinder wheel arbors in the 1/2 inch to 3/4 inch range.

Key Features

• Telescoping design fits 1/2 inch, 5/8 inch, and 3/4 inch ID arbors from a single bushing
• 1 inch outside diameter for standard wheel bore fitment
• 15/16 inch thickness provides stable wheel seating on the arbor
• Reduces the need to stock multiple single-bore bushing sizes
• Lightweight at 0.15 pounds for easy handling during wheel changes

Compatibility

Designed as an OEM-style replacement and standard fitment bushing for abrasive wheels requiring a 1 inch bore with arbor sizes of 1/2 inch, 5/8 inch, or 3/4 inch.

Installation Notes

Installation is typically performed by a machinist or maintenance technician. Always power down and disconnect the grinder or tool from its power source before removing or installing any wheel or bushing. Ensure the bushing is fully seated and centered in the wheel bore before tightening the arbor nut. Follow the tool manufacturer's torque guidelines and all applicable ANSI B7.1 safety standards for abrasive wheel mounting.
