Keyless Locking Devices
Traditionally, shafts and hubs have been connected using keys and keyways. However, this method presents numerous challenges, including the need for high dimensional accuracy and precise alignment during assembly. ETP Bushings & Posilocks solve these problems by providing a friction-based connection. A simple tightening of the bolts ensures a precise and secure connection.

Hydraulic type (ETP bushing)
The shaft and hub are connected by friction when pressure is applied to the pressure medium sealed inside the unit. It requires at least one bolt.
