31.5-40MM,UN Radial Shaft Hydraulic Seal (IDxODxTHK), Polyurethane Piston Rod PU Single Lip U Cup Oil O-Ring(33x48x10(3pcs))

[Advantage]: Widely used in the hydraulic cylinder to prevent dust, dirt, sand, and metal debris from entering, and easy to install
[Application]: Applied to industrial hydraulic cylinders and cylinders, hoists, moving rods of guide rods, and piston rods (pull rods), and pistons (1-way piston seals) in static pressure
[UN Radial Rotary Shaft Oil Seal]: The UN-type oil seal's inner and outer sealing lip are the same height, with a Y-shape cross-section. Polyurethane (PU) seal is oil resistance, wear resistance, low-temperature resistance, aging resistance, high hardness, elasticity, and easy to install. Advantage Good wear resistance, extrusion resistance, impact resistance, compression deformation, the most suitable for harsh working conditions, and easy to install.
[Wide Application]: 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 heavy-duty walking machinery or industrial hydraulic cylinders and cylinders, hoists, axial moving rods of guide rods, and piston rods (pull rods) and pistons (1-way piston seals) in static pressure. Both piston and piston rods can obtain a good sealing effect.
