Product Description
U-ring with wiper lip
--Lightly rounded edge of wiper lip
-A two-way acting PU dust ring. It possesses two sealing lips of different geometries.
-Designed to remove dust while retaining a residual lubrication film on the retracting rod . collect traces of fluid passing the rod seal.
-Use radial pressure to prevent water.dust, dirt, sand and metal debris from entering the cylinder.Reduces scratches on the rod caused by external contaminants intruding into the guide sleeve, extending the working life of the rod seal.
*When the inner lip is under pressure, the inner lip has a sealing effect; the pressure outside the groove can form a static sealing.

If the pressure is high,a pressure relief oil return hole should be provided in front of the double-lip dust seal to prevent pressure from building up between the sealing ring and the dust seal.
Due to our unique mahcined process, in addition to the above ordinary cross-sections, we can machined seals of any size and material according to customers' customized drawings.
