Hebei Hankai replacing seals in a hydraulic cylinder

Combi oil seals are typically made of high-quality materials such as rubber, silicone, or polyurethane. These materials are chosen for their durability, flexibility, and resistance to wear and tear. The seals are designed to withstand high temperatures, high pressures, and harsh operating conditions without compromising their sealing performance.

2. Inspection Once disassembled, thoroughly inspect the seals and other cylinder components for wear, damage, or deformation. It's essential to assess not only the seals but also the cylinder bore, piston, and any other related parts. This inspection will help determine the root cause of the failure and whether other components need replacement.

Shaft oil seals typically consist of a flexible sealing lip made from elastomeric materials such as rubber, polyurethane, or silicone, encased in a sturdy outer shell. The sealing lip makes contact with the rotating shaft, creating a barrier that effectively retains lubricants while blocking unwanted particles. The design may include additional features such as garter springs to maintain contact with the shaft and improve sealing effectiveness over time.

3. Specific Application Different applications may require specific types of seals. Understanding the working conditions, such as pressure and temperature ranges, helps in selecting the most appropriate seals.
