10A991 - Walter 40mm OD to 1-1/4 ID Arbor Adapter Ring

Precision Engineering for Industrial Safety

In the realm of industrial metalworking, the compatibility between abrasive consumables and power equipment is paramount for both performance and safety. The Walter 40mm to 1-1/4" Bushing (SKU: 10A991) is a specialized accessory designed to bridge the gap between metric wheel specifications and imperial machine spindles. Manufactured by Walter Surface Technologies, a leader in surface treatment solutions, this bushing is engineered to meet the rigorous demands of heavy-duty cutting applications.

Stationary cut-off machines operate at high rotational speeds and exert significant torque during the cutting process. Using a wheel with an improper arbor fit can lead to catastrophic failure, excessive vibration, and poor cut quality. This precision-machined bushing effectively reduces a 40mm arbor hole—common in certain European or specialized abrasive wheels—to a standard 1-1/4 inch diameter, which is prevalent in many North American stationary saws. By ensuring a tight, concentric fit, the bushing eliminates radial play, ensuring that the wheel remains perfectly centered throughout operation.

Optimizing Equipment Versatility

Industrial facilities often manage a diverse inventory of machines and consumables. The ability to adapt specific wheels to different machines increases operational flexibility and reduces waste. The Walter 10A991 bushing allows shop managers to utilize high-performance 40mm bore wheels on existing 1-1/4" shaft equipment without the need for expensive machine modifications. This adaptability is crucial for maintaining workflow efficiency when specific abrasive grades are required that may only be available in specific bore sizes.

Durability and Performance

Unlike generic plastic adapters that may deform under the heat and pressure of industrial cutting, Walter bushings are constructed from durable materials designed to withstand the harsh environment of metal fabrication. The structural integrity of the bushing ensures that it maintains its dimensions over time, providing a reliable mounting surface for the life of the wheel. When installed correctly, this accessory contributes to smoother cuts, reduced machine wear, and, most importantly, a safer working environment for the operator. Trust in Walter's commitment to quality to keep your stationary cut-off operations running smoothly and safely.
