UN oil seal advantages: good wear resistance, extrusion resistance, impact resistance, compression deformation, the most suitable for harsh working conditions and easy to install.

UN oil seal is the most widely used oil seal in the hydraulic cylinder, whose main function is to prevent dust, dirt, sand and metal debris from entering. It is mainly used for sealing and dustproof of heavy-duty walking machinery or industrial hydraulic cylinders and cylinders, hoists, axial moving rods of guide rods, and piston rods (pull rods) and pistons (one-way piston seals) in static pressure. Both for piston and piston rod can obtain good sealing effect.
