10A989 - 1-Inch to 20mm Arbor Adapter Ring

Maximize Tool Compatibility with Walter Reducer Bushings

The Walter 10A989 Reducer Bushing is a critical accessory for industrial fabricators, metalworkers, and tradespeople who require versatility in their tooling inventory. In the diverse world of power tools and abrasives, arbor sizes can often vary between manufacturers and regions, leading to compatibility issues where a perfectly good wheel cannot be mounted on a specific machine. This precision-engineered bushing solves that problem by effectively reducing a 1-inch arbor hole to accommodate a 20mm spindle.

Manufactured by Walter Surface Technologies, a leader in surface treatment technologies, this bushing is designed to meet high standards of safety and performance. Unlike generic, ill-fitting adapters that can cause dangerous wobbling or runout, the Walter 10A989 provides a snug, concentric fit. This ensures that the abrasive wheel or saw blade remains perfectly centered on the shaft, maintaining the balance necessary for high-speed rotation. Proper centering is vital not only for the quality of the cut or grind but also for the longevity of the machine's bearings and the safety of the operator.

This bushing is compatible with a wide array of consumables, including cutoff wheels, grinding discs, and circular saw blades. By keeping a stock of these reducers, workshops can standardize their wheel inventory without being limited by the spindle specifications of individual machines. Whether you are adapting a domestic blade for a metric saw or utilizing specialized abrasives on different grinders, this simple yet robust component is the key to seamless integration.

Key Technical Benefits

• Precision Fit: Machined to exact tolerances to eliminate play between the wheel and the shaft.
• Versatility: Bridges the gap between imperial (1 inch) and metric (20mm) standards.
• Safety: Reduces the risk of wheel imbalance and vibration during operation.
• Durability: Constructed from high-quality materials to resist deformation under torque.

Invest in the Walter 10A989 Reducer Bushing to ensure your shop remains flexible and efficient. It is a small component that makes a significant difference in tool utilization and operational safety.
