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-sided sleeve and enlarge the hub-sided sleeve to fasten a shaft and hub through the sleeve. Since the ETP-EXPRESS uses only one pressure screw to fasten, assembling time of equipment requiring a positioning can be substantially reduced. It is also useful for the place requiring a repetitive mounting and dismounting. A stainless steel specification (ETP-E-R type) resistant to environment is also available as standard.

By the pressurization of a pressure medium, the sleeve is pressured from inside to contract the shaft-sided sleeve and enlarge the hub-sided sleeve to fasten a shaft and hub through the sleeve. Since the ETP-TECHNO uses only one pressure screw to fasten, assembling time of equipment requiring a positioning can be substantially reduced. It is also useful for the place requiring a repetitive mounting and dismounting. Furthermore, a high-precision mounting and ultrahigh-precision positioning can be performed due to its excellent concentricity of 0.006 mm. A simple anti-rust specification with electroless nickel plating (ETP-T-C) is also available. ETP-T TypeOnly one pressure screw allows easy and quick mounting and dismounting.

The ETP-T-C type is a simple anti-rust specification with electroless nickel plating.

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 enlarge the hub-side sleeve to fasten a shaft and hub through the sleeve. Compared with a mechanical-type fastening element, the number of bolts to be used is small. Also, a high-precision fastening is possible with no slotting. A large variety of specifications such as hexagon bolt, simple antirust with electroless nickel plating, stainless steel or short sleeve specification are available.

The POSI-LOCK is a mechanical-type shaft lock joint. Fasting of clamping bolt produces a wedge effect to perfectly fasten a shaft and hub. The PSL-K type with a small inner and outer diameter ratio of the sleeve to reduce diameters of parts, PSL-G type for a general specification and PSL-D type designed for a medium load with a small surface pressure to reduce diameters and weight of mounted part are available. Also, a large variety of specifications such as simple antirust with electroless nickel plating or stainless steel specification are available.

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 dia. 50mm. Since the oil pressurization has an effect on the taper piston displacement only, no pressure is applied after fastening. The fastening power is maintained only by the wedge effect of the taper piston.
