12E006 - Walter Reducing Bushing Set, 1-1/4 in. OD to 1/2, 5/8, 3/4, 1 in. ID, 3/4 in. Width

Universal Arbor Adaptation for Bench Grinders

The Walter Surface Technologies 12-E-006 Reducing Bushing is a critical accessory for industrial maintenance and fabrication shops utilizing bench grinders and stationary finishing equipment. Designed to bridge the gap between standardized abrasive wheel manufacturing and the varied shaft sizes found on bench grinders, this telescopic bushing set ensures seamless compatibility and operational safety. Many high-performance bench grinding wheels and wire brushes are manufactured with a standard 1-1/4 inch arbor hole to accommodate heavy-duty industrial machinery. However, a significant portion of equipment in the field utilizes smaller shaft diameters, typically 1 inch, 3/4 inch, 5/8 inch, or 1/2 inch. This bushing set effectively adapts the larger arbor to these smaller shafts without compromising concentricity.

Constructed from high-quality, compression-resistant polymer, the bushing is designed to withstand the clamping forces exerted by the grinder flanges without deforming or cracking. The telescopic or nested design allows the user to simply snap out the unneeded rings to achieve the desired inner diameter, providing a custom fit for the specific machine at hand. With a width of 3/4 inch, it is sized to match the hub thickness of standard bench grinding wheels and wire brushes, ensuring that the wheel is properly supported across its width on the shaft. Proper bushing fitment is essential not just for mounting, but for safety; a loose or improper fit can lead to wheel vibration, imbalance, and potential disintegration at operating speeds.

This product is an indispensable inventory item for tool cribs, ensuring that any 1-1/4 inch arbor wheel in stock can be immediately deployed on any grinder in the facility, regardless of shaft size. It eliminates the downtime associated with sourcing specific arbor sizes and reduces the need to duplicate inventory for different machines.
