Taper Lock Bush is a standardized shaft mounting component widely used to connect pulleys, sprockets, timing pulleys, gears, and couplings to shafts. By means of a tapered surface and tightening screws, the bush creates a strong clamping force between the shaft and the hub, ensuring a reliable, concentric, and detachable mechanical connection.
Taper lock bushes offer easy installation, high interchangeability, and precise positioning without complex machining, making them one of the most popular shaft fixing solutions in modern modular power transmission systems.

Features
1.Quick installation and removal
Assembly and disassembly can be completed easily by tightening or loosening the screws.
2.High concentricity connection
Self-centering taper design ensures accurate alignment between hub and shaft.
3.Strong torque transmission
Frictional grip on the tapered surface provides reliable high torque capacity.
4.Reduced shaft machining (optional keyless use)
Minimizes shaft processing cost and reduces stress concentration.
