Climax Metal 5/8" ID X 3/4" OD Shaft Adapter Bushing

The Climax Metal SRB-101220 is a precision-engineered shaft adapter bushing designed for industrial and HVACR mechanical power transmission applications. This 5/8" ID x 3/4" OD reducer bushing allows for the seamless adaptation of larger bores in pulleys, sheaves, and sprockets to smaller diameter motor shafts. Constructed from high-quality cold finished steel with an oxide finish, this adapter ensures a high-tolerance fit that minimizes vibration and mechanical runout. With a total length of 1-1/4", the SRB-101220 shaft reducer provides sufficient surface contact to maintain torque transfer integrity without the need for immediate shaft replacement. This steel shaft adapter is an essential component for technicians performing field retrofits where bore diameter conversion is required to match mismatched mechanical components. Its rigid construction prevents wall deformation under load, ensuring the mechanical shaft coupling remains secure during continuous operation in high-torque environments.

• Precision Tolerance: Ensures a tight 5/8 to 3/4 shaft conversion to prevent keyway slippage and equipment wear.
• Durable Material: Manufactured from robust steel to withstand the radial loads associated with HVAC blower motors and pump drives.
• Corrosion Resistance: Protective coating helps prevent seizing and facilitates easier removal during future maintenance cycles.
• Versatile Application: Ideal for varying bore sizes on fan blades, blowers, and industrial drivetrain components.

Can this bushing be used with a standard keyway?
Yes, this shaft adapter sleeve is designed to work in conjunction with existing keyways to maintain a locked drive connection between the shaft and the driven component.

What is the primary application for a 5/8" ID to 3/4" OD adapter?
It is most commonly used in HVACR motor retrofits where a 3/4" bore pulley needs to be mounted onto a 5/8" motor shaft.

Does the 1-1/4" length provide enough stability?
The 1.25-inch length is the industry standard for ensuring adequate surface area contact, preventing axial movement and preserving the service life of the power transmission assembly.
