Wiper oil seals, commonly referred to as lip seals or simply oil seals, are mechanical seals used to keep lubricants in and contaminants out of machinery. They are typically made from durable materials such as rubber or elastomers, designed to withstand high pressures and temperatures. The primary function of these seals is to maintain a barrier that prevents the escape of oil, while also preventing dirt, dust, and other contaminants from infiltrating the system.

5. Reassemble and Test After replacement, carefully reassemble the hydraulic cylinder. Once reattached to the hoist, test its operation without excessive loads to ensure it functions properly.

Oil seals serve multiple critical functions in machinery. They are designed to

High-pressure oil seals are specifically engineered to withstand elevated pressures that are common in many industrial settings. These seals feature reinforced designs, which may include additional radial or axial support to help manage the stresses of high pressures. The materials used in high-pressure seals also play a crucial role; they must be able to maintain their integrity and elasticity under extreme conditions, resisting deformation and fatigue over time.

In industrial machinery, these oil seals are critical for applications involving pumps, motors, and gearboxes. The demand for reliable sealing solutions in these machines is high, given their continuous operation and the need for maintenance-free performance. The 20x35x7 oil seal's ability to handle a range of temperatures and pressures makes it suitable for diverse operational settings.
