OVERVIEW

Precision Arbor Adaptation for Industrial Abrasives

The Walter 48H420 Reducing Bushing is an essential accessory for industrial workshops and fabrication environments where equipment versatility is paramount. Designed by Walter Surface Technologies, a leader in surface treatment solutions, this bushing is engineered to seamlessly adapt abrasive wheels and wire brushes with a standard 7/8-inch arbor hole to fit onto machinery with a 5/8-inch shaft. This capability allows operators to utilize a broader range of consumables across different types of grinding equipment, including bench grinders, pedestal grinders, and specialized stationary machinery.

Safety and precision are critical when operating high-speed abrasive equipment. A loose or improperly fitted wheel can lead to dangerous vibrations, poor finish quality, and potential operator injury. The Walter 48H420 is manufactured to strict tolerances, ensuring a snug, concentric fit that eliminates play between the wheel and the shaft. This precise centering is vital for maintaining the balance of the rotating assembly, thereby reducing wear on the machine's bearings and extending the life of the abrasive product itself.

Constructed from high-quality, durable polymer materials, this bushing is designed to withstand the compressive forces exerted by mounting flanges without cracking or deforming. Unlike makeshift solutions, this purpose-built adapter maintains its structural integrity even under the thermal and mechanical stresses of continuous industrial use. It serves as a reliable interface that dampens minor vibrations, contributing to a smoother operation and a more consistent surface finish on the workpiece.

Whether you are managing a large inventory of abrasive consumables or simply need to fit a specific Walter wire wheel onto a standard 5/8-inch spindle, the 48H420 bushing offers a simple, reliable solution. It represents the attention to detail and commitment to safety that professionals expect from Walter Surface Technologies products.

FAQ

The Walter 48H420 bushing reduces a 7/8-inch arbor hole to fit a 5/8-inch shaft.

It is typically manufactured from a durable, high-density polymer plastic designed to resist cracking and dampen vibration.

This bushing is primarily designed for bench or pedestal grinders with smooth shafts. Most angle grinders use a 5/8-11 threaded spindle or a flange system that does not require this specific type of insert.

Yes, provided it has not been deformed or damaged during use, it can be removed and used on other compatible wheels.

While designed for Walter products, it will generally fit any abrasive wheel or brush with a standard 7/8-inch arbor hole, provided the thickness is compatible.

Plastic bushings are often preferred for certain applications as they can help dampen vibration, are resistant to corrosion, and are less likely to seize onto the shaft.

This SKU typically refers to a single unit, but check the specific packaging quantity listing as they are sometimes sold in bulk.

Simply press the bushing into the 7/8-inch arbor hole of your wheel or brush until it sits flush, then mount the wheel onto the 5/8-inch shaft of your machine.
