12E010 - Walter 1-1/4 Inch to 1/2 Inch x 1 Inch Nested Arbor Bushing Set

Versatile Arbor Adaptation for Industrial Abrasives

The Walter 12E010 Nested Bushing Set is an essential accessory for industrial workshops and fabrication facilities utilizing bench grinders, pedestal grinders, or stationary finishing machinery. Designed to maximize the versatility of your abrasive inventory, this bushing set allows wheels with a standard 1-1/4 inch arbor hole to be safely and securely mounted onto machines with smaller shaft diameters. This flexibility reduces the need to stock duplicate wheels for different machines, streamlining inventory and reducing operational costs.

This set is engineered with precision to ensure a concentric fit, which is critical for high-speed abrasive applications. A loose or poorly fitted wheel can cause dangerous vibration, poor surface finish, and premature wear on machine bearings. The Walter nested bushings fill the gap between the wheel arbor and the shaft, centering the wheel perfectly to maintain balance during rotation. The set includes reduction rings to accommodate the most common industrial shaft sizes: 1 inch, 3/4 inch, 5/8 inch, and 1/2 inch.

With a width of 1 inch, these bushings are perfectly sized for standard bench grinding wheels, wire brushes, and flap wheels. The nested design means the bushings fit inside one another or can be used individually depending on the required reduction. Whether you are setting up a new grinding station or replacing worn adapters, the Walter 12E010 set provides the reliability and performance expected from a leader in surface technologies.

Key Benefits for Industrial Users

• Universal Compatibility: One set covers four different shaft sizes, ensuring you always have the right adapter on hand.
• Vibration Control: Ensures a tight, centered fit to minimize wobble and vibration during operation.
• Inventory Efficiency: Allows the use of 1-1/4" arbor wheels across multiple machines with different specs.
