A broad range of taper bushes and of locking devices, to meet the needs of all customers.
The taper bush utilizes the working principles both of a locking device and of a key. It was invented to simplify and improve the conventional use of pairing by means of a key.
The fixing system by means of key is based on the friction principle: by means of pushing cones, a pressure between shaft and hub is generated, which allows to fix pulleys, gears, chain wheels, drums, flywheels, safely and securely.
