Blue PU UN Oil Seal For Hydraulic

Piston and piston rod seals are usually assembled with interference fit. In order to avoid damage during installation, it is necessary to provide chamfered or rounded edges on the cylinder bore or piston rod. If this is not possible due to design reasons, a separate installation tool is required. The length of the chamfer introduced depends on the external dimensions of the seal. The reliability and service life of seals are largely determined by the quality and surface finish of the sealing mating surface. Scratches, scratches, pores, concentrated processing marks or spiral processing marks are not allowed. The surface finish of the dynamic fit is higher than the requirement at rest.
