Hydraulic Cylinder Oil Seal

The 40% - 80% - 10% Principle

Typically made from elastomeric materials like nitrile rubber (NBR), fluorocarbon rubber (FKM), or silicone, oil seals are engineered to withstand varying temperatures, pressures, and chemical environments. The choice of material affects their performance characteristics, including resistance to wear, deformation, and aging. The design of the oil seal includes a sealing lip, which provides a barrier against leaks while maintaining a low coefficient of friction against the shaft.

Hydraulic piston oil seals are designed to facilitate the movement of a piston within a hydraulic cylinder while keeping the hydraulic fluid contained within the chamber. They play a crucial role in maintaining pressure, preventing leaks, and protecting the internal components of the hydraulic system from contaminants. Typically made from materials like rubber, polyurethane, or PTFE (Teflon), these seals can be tailored to suit various temperature ranges, pressures, and chemical exposures, making them incredibly versatile.
