48H420 - Walter 7/8 to 5/8 Inch Reducing Bushing for Abrasive Wheels

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.
