ETP Bushings (Shaft Lock)

A shaft and hub are conventionally fastened by a key and keyway. However, this method has many problems such as quality evolution of material, high processing accuracy or position adjustment when assembling. These problems can be solved by ETP BUSH that offers a frictional fastening. The ETP BUSH is a product to fasten a shaft and hub without using a key, resolving disadvantages or difficulties of key fastening. There are two types of mechanism, the hydro type (hydraulic type) and mechanical type (wedge type) . It is simple, compact and lightweight model. Mounting, dismounting, correct positioning and indexing are easy. Work from design through assembly, adjustment and maintenance can be substantially reduced.

ETP-EXPRESS (R)
Only one pressure screw allows easy and quick mounting and dismounting. A pressure medium sealed inside of the chamber is pressurized by fastening the pressure screw, and moves equally into the sleeve. By the pressurization of a pressure medium, the sleeve is pressured from inside to contract the shaft-side...more
