Climax Metal 1/2" ID x 5/8" OD x 1-1/16" Length Shaft Adapter Bushing

This Climax Metal 1/2" ID x 5/8" OD x 1-1/16" Length Shaft Adapter Bushing is a precision-engineered solution for adapting pulleys, sheaves, and various drive components to smaller diameter motor shafts. Manufactured from high-quality cold finished steel, this shaft reducing bushing ensures a concentric fit between a 1/2-inch shaft and a 5/8-inch bore, maintaining drive train alignment and reducing vibration in HVACR blower assemblies and mechanical power transmission systems. The 1-1/16-inch length provides ample surface contact for high-torque applications, preventing slippage and component wear. As a standard mechanical shaft adapter, it simplifies inventory by allowing contractors to utilize existing components on mismatched shaft sizes without the need for custom machining. This industrial steel bushing is essential for field retrofits where motor frame sizes or shaft specifications have changed, providing a reliable bore size conversion that meets tight tolerances for commercial and industrial fan drives.

• Precision Bore Alignment: Maintains concentricity between the 1/2" shaft and 5/8" accessory to prevent shaft runout.
• Durable Construction: Built from robust steel for long-term performance in high-RPM HVACR blower and pump applications.
• Streamlined Retrofitting: Allows for immediate installation of 5/8" bore pulleys on 1/2" shafts, reducing downtime during emergency motor replacements.
• Standardized Dimensions: The 1-1/16" length ensures full engagement across the hub of most standard sheaves and couplings.

How do I ensure this shaft adapter won't slip during high-torque startups?
Proper installation involves aligning the bushing with the component's keyway (if applicable) and ensuring the set screws of the pulley or coupling are tightened directly onto the adapter or through the slot to secure it to the 1/2" shaft.

Can this bushing be used for permanent motor shaft diameter changes?
Yes, this shaft diameter adapter is designed for permanent installation in power transmission setups, provided the load requirements do not exceed the shear strength of the steel bushing and the host shaft.

Is this adapter compatible with keyed shafts?
This specific bushing is a sleeve style; for applications requiring a keyway, the technician may need to utilize a keyed bushing or ensure the set screw penetration is sufficient to lock the assembly.
