Climax Metal 1/4" ID X 5/16" OD Shaft Adapter Bushing

The Climax Metal SRB-040516 is a precision-engineered shaft adapter bushing designed for commercial HVACR and industrial mechanical applications. This 1/4" ID x 5/16" OD bushing provides a reliable solution for adapting larger bore pulleys, gears, or fan blades to smaller diameter motor shafts. Constructed from high-quality steel for durability under high-torque conditions, this 1-inch long reducing sleeve ensures a concentric fit, minimizing vibration and shaft runout in critical drive assemblies. When replacing HVAC blower motor parts or refurbishing mechanical equipment, using a dedicated shaft reducer bushing preserves the integrity of the drive components without requiring expensive shaft replacements. The SRB-040516 is essential for maintenance technicians who need to bridge bushing sizes quickly and effectively in the field. This climax metal bushing is machined to tight tolerances, ensuring compatibility with standard power transmission systems and industrial hardware configurations.

Key Benefits

• Ensures accurate shaft diameter conversion for 1/4 inch shafts into 5/16 inch bores.
• Reduces downtime by allowing the use of existing stock components on mismatched motor shafts.
• Durable steel construction maintains structural integrity in high-RPM operations.
• One-inch length provides ample surface contact for secure setscrew engagement.
• Eliminates the need for custom-machined parts during emergency mechanical repairs.

Common Questions

How do I install a shaft adapter bushing on a motor?
Clean the motor shaft and the inner diameter of the bushing thoroughly. Slide the Climax Metal SRB-040516 over the 1/4" shaft, then slide the component over the 5/16" OD of the bushing. Align the setscrew of the component with the bushing to ensure a tight, secure grip.

Can these bushings be used with high-speed fan motors?
Yes, these shaft reducers are machined for balance and concentricity, making them suitable for standard fan motor speeds found in HVACR equipment, provided they are installed and tightened correctly.

What is the difference between a shaft adapter and a spacer?
A shaft adapter bushing like the SRB-040516 is specifically designed to change the effective diameter of a shaft, whereas a spacer is typically used to manage end-play or axial positioning along the shaft.
