Gates Miscellaneous Metal Products

This Gates taper lock bushing provides a secure, self-locking shaft connection for sheaves, sprockets and coupling hubs. The taper lock principle allows easy component removal without shaft damage — essential for scheduled maintenance on large drive pulleys. Gates taper lock bushes follow the standard flange bore profile and are interchangeable with other brands of the same designation.

Where this product is used

Gates taper lock bushings provide a secure, removable shaft connection for pulleys, sheaves and sprockets. Common applications include:

• Fixing sheaves, sprockets, pulleys and coupling hubs to shafts in industrial belt drive systems
• Easy installation and removal of drive components without shaft damage — key for scheduled maintenance
• High-torque drives in mining, quarrying and heavy industry where secure shaft attachment is critical

Key specifications

Selecting the right option

Select the taper lock bush by the flange bore (4535, 4030, 3535 etc.) and the required shaft bore diameter. The 4535 range covers imperial bore sizes up to 4¼ in. Confirm the bush number matches the sheave or sprocket taper bore specification — taper lock flanges are brand- and size-specific and will not interchange. Contact AIMS for assistance selecting the correct bush for your drive.
