Product
Description

Hydraulic oil seals are sealing components designed for hydraulic systems and are widely used in hydraulic pumps, hydraulic cylinders, hydraulic motors and other equipment. Their main function is to prevent hydraulic oil leakage and prevent external pollutants (such as water, dust, etc.) from entering the hydraulic system to ensure the normal operation of hydraulic equipment. Hydraulic oil seals are usually composed of a metal frame, a rubber sealing lip and an oil return groove. The metal frame provides the necessary support, while the rubber sealing lip plays a sealing role. It can withstand high pressure, high speed and harsh working conditions in hydraulic systems, has excellent oil resistance, wear resistance, high temperature resistance and other characteristics, and is widely used in industry, automobiles, engineering machinery and other fields.
