Hydraulic seal
A hydraulic seal is a relatively soft, non-metallic ring, captured in a groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear motion. For example, they are widely used in hydraulic cylinders of excavators, bulldozers, cranes, and many other types of heavy equipment.
Hydraulic seals also play a crucial role in hydraulic lifting equipment, such as lift tables, by ensuring the efficient and safe operation of hydraulic cylinders.
