GSZ – wiper seal
other name: AD, C452
The function of wiper rings is to prevent dust, dirt, grains of sand and metal swarf from penetrating into axially moving rods and plungers. Thus the development of scratches is largely prevented, guiding elements and seals are protected and the working life of the sealing system is extended.
Profile GSZ(AD) consists of a PTFE wiper ring and an elastomer O-ring as a preloading element. It combines two functions: wiping against pollution from outside and a sealing function which reduces the residual oil film.
The material combination of the slipper ring (PTFE) and the O-ring (elastomer) makes this product suitable for a wide range of applications, especially for aggressive media and/or high temperatures. Multiple compounds can alternatively be selected according to the individual application profile.
Features
Excellent wear resistance.
Minimal break-away and dynamic friction and no stick-slip tendency ensuresuniform motion even at low speeds.
Good energy efficiency due to low friction.
High temperature resistance assured by suitable O-ring compound selection.
Adaptable to nearly all media thanks to high chemical resistance of the sealingring and large O-ring compound selection.
Available in diameters from 4 to 3000 mm.
Installation in closed and undercut housings.
Range of application
Operating temperature | -30 °C to +100 °C |
with FKM O-ring | -30 °C to +200 °C |
Sliding speed | ≤ 4 m/s |
