UN / U / Y Type Ring Polyurethane (PU) Hydraulic Oil Seal Cylinder Piston Sealing ring Gasket ID 46 48 50 mm 2Pcs
Widely used in the hydraulic cylinder to prevent dust, dirt, sand, and metal debris from entering, and easy to install
45mmx55mmx6mm Y-shape 90A mechanical seal for piston and piston rod
Working Speed: Less than 0.5m/s; Working Pressure: Less than 35Mpa; Working Temperature Range: -35°C to 100°C (-31°F to 212°F)
Oil resistance, wear resistance, low-temperature resistance, aging resistance, high hardness, elasticity
Applied to industrial hydraulic cylinders and cylinders, hoists, moving rods of guide rods, and piston rods (pull rods), and pistons (one-way piston seals) in static pressure
UHS Radial Rotary Shaft Oil Seal
The UHS-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
UHS 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 (one-way piston seals) in static pressure. Both piston and piston rods can obtain a good sealing effect.
