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-TECHNO (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

ETP-CLASSIC (R)

The clamping bolts placed on the flange surface allow easy and quick mounting and dismounting. A pressure medium sealed inside of the sleeve is compressed by fastening the clamping bolt. By the compression of a pressure medium, the sleeve is pressured from inside to contract the shaft-side sleeve and enlarg...more

ETP-HYLOC (R)

By pressing oil into the sleeve by a pump to move the wedge of built-in taper piston, the sleeve is pressured from inside to contract the shaft-sided sleeve and enlarge the hub-sided sleeve to fasten a shaft and hub tightly through the sleeve. The maximum allowable torque is 2600Nm for a shaft diameter 50mm...more
