Climax Metal Products SRB-050617 Bushing

The Climax Metal Products SRB-050617 is a precision-engineered galvanized split steel reducer bushing designed for industrial shaft diameter adjustments. This shaft adapter bushing features a 5/16" Inside Diameter (I.D.) and a 3/8" Outside Diameter (O.D.), with an overall length of 1-1/16". Engineered from high-quality cold-rolled steel with a galvanized finish for enhanced corrosion resistance, the split-sleeve design allows for slight expansion and contraction, ensuring a tight interference fit on motor shafts and drive components. This component is essential for contractors needing to adapt larger bore pulleys, saws, or grinding wheels to smaller diameter shafts without replacing the entire assembly. The SRB-050617 maintains concentricity and torque transmission efficiency in high-RPM HVACR applications, providing a cost-effective solution for resizing mechanical interfaces in the field. Its robust construction ensures long-term mechanical durability under thermal cycling and heavy vibration loads.

Key Benefits

• Precision Sizing: Facilitates seamless conversion of a 3/8" bore to a 5/16" shaft diameter.
• Galvanized Finish: Provides a protective barrier against oxidation and moisture in demanding HVACR environments.
• Split-Sleeve Design: Enables easier installation and a more secure grip compared to solid bushings.
• Industrial Strength: Constructed from rigid steel to withstand high rotational forces and mechanical stress.
• Versatile Application: Compatible with various pulleys, fans, and power transmission components.

Common Questions

How do I ensure a secure fit with a split steel bushing?
Ensure the shaft is free of burrs or debris. The split design is intended to compress slightly when the mounting hardware of the pulley or hub is tightened, creating a friction fit.

Can this bushing be used on keyed shafts?
Standard split bushings like the SRB-050617 are typically used in non-keyed applications or where a setscrew can pass through the split to reach the shaft, though some technicians mill a temporary keyway if specific torque requirements demand it.

Is the galvanized coating suitable for outdoor equipment?
Yes, the galvanization provides significant protection against environmental elements, making it suitable for rooftop units and condenser fan applications.
