The primary function of an oil seal for a rotating shaft is to retain the lubricating oil within the system and prevent it from leaking out. This is important for maintaining proper lubrication of the bearings and moving parts, which helps to reduce friction and wear, and prolong the life of the equipment. Without a properly functioning oil seal, oil leakage can lead to equipment failure, costly repairs, and downtime

Moreover, the rigidity of the metal case ensures better dimensional stability, reducing the risk of deformation under pressure. This is particularly beneficial in dynamic sealing applications where the seal is subjected to continuous movement. The metal casing also improves the seal's performance in situations where there is a significant difference in temperature between the seal and the surrounding environment The metal casing also improves the seal's performance in situations where there is a significant difference in temperature between the seal and the surrounding environment

Polyurethane is another popular material used in hydraulic cylinder seal kits. Polyurethane seals are known for their exceptional wear resistance, high flexibility, and excellent sealing properties. These seals are ideal for applications where there is a need for high pressure and high-speed operation. Polyurethane seals are also resistant to abrasion, making them suitable for heavy-duty applications.
