Application Range
Composed of a special shaped ring with sealing and dust-proof cutting edges and two O-rings, the JPT1 dust-proof ring is used for improving the integral sealing; it has the characteristics of low friction with no stick-slip phenomena and possesses excellent capability of adjustment and positioning. JPT1 can apply to agricultural machinery, hydraulic machines, injection molding machines, hydraulic control systems, forklifts, cranes, rolling and loading, unloading machines, etc.
Please refer to the standards of WEMHF series of Trellebrg Company and PT1 series of Merker Company when designing and selecting.
Features
Double lip dust-proof ring can be used to improve the integral sealing
