A wiper seal is an axial seal that creates a seal while allowing a reciprocating shaft to pass through the seals inner bore. The role of the wiper seal is to prevent the ingress of dust and dirt or other foreign bodies, therefore extending the working life of the seal it is protecting.All other functions, such as providing a secondary seal for the rod, are subordinate to this prime.Wiper seals are typically used on hydraulic and pneumatic cylinders, as well as telescopic suspension forks for motorcycles and bicycles.Temperature range of wiper seals is usually between -40° C and +120 ° C and max speed is at 4m/s.
