Keyless Bushes

Keyless bushes are a type of cylindrical metal bearing that is used in power transmission in pneumatic and hydraulic systems. They provide a connection between a shaft and a hub and fit onto the shaft without marking it, which means that they eliminate the wear and tear caused to mounted components by other types of bushings, such as taper bushes or connections.

How do keyless bushes work?

Keyless bushes are mounted onto a shaft and then kept there using hydraulic pressure, which means that there is less chance of any micro-movement, which can sometimes cause fretting, where the part is worn away. You simply need to set them in position and lock them with a torque wrench. After installation they are easy to adjust both radially (around the shaft) and axially (parallel to the shaft), meaning there is minimal time where the machine or part is out of action.

Types of keyless bushes

Keyless bushes all function similarly, but they come in varying sizes in terms of both their shaft diameter and outside diameter, as well as having a broad range of maximum torque, which is the rotational force that can be applied to the bush.
