Daikin-McQuay Split Taper Bushing Bore Manual Transmission Bearing

Daikin-McQuay split taper bushings, also called taper bushings or sheave bushings, mount a sheave, pulley or sprocket securely on a shaft. They are OEM replacement power transmission components for Daikin-McQuay HVAC equipment such as air handlers and fans, where belt-driven sheaves need a dependable shaft connection.

Key Features:

• Split taper design: A flanged, tapered barrel with a split clamps between the shaft and the sheave hub as the cap screws are tightened. This gives a firm, concentric grip.
• Positive shaft retention: Wedging the taper into a matching tapered bore helps resist slippage and supports torque transfer under load.
• Bolted flange: The flange takes the cap screws that draw the bushing and hub together. The same screws are used to remove it.
• Genuine Daikin-McQuay OEM part: Choosing the original manufacturer's bushing helps maintain the fit and function the equipment was built around.
• Multiple bore sizes and bushing series: Each variant is listed under its own part number, so you can match the bushing to your shaft and sheave.

Installation Notes: Before installing, make sure the shaft, bushing and sheave bore are clean and free of burrs and paint. Tighten the cap screws evenly and in sequence to the manufacturer's recommended torque. Mounting on a shaft smaller than the bushing's rated range can cause a faulty assembly.

Select the child item that matches your shaft diameter and sheave bushing series to restore reliable belt-drive operation.
