Hebei Hankai hydraulic cylinder seals

In various mechanical and industrial applications, seals play a crucial role in ensuring the longevity and efficiency of equipment. Among the many types of seals available, dust seals and oil seals are two predominant types that serve critical functions. While they may appear similar at first glance, their purposes, designs, and applications differ significantly. This article aims to explore these differences, helping you understand when and why to use each type.

Rotary lip seals function on the principle of pressure differential. As the shaft rotates, the sealing lip exerts a force against the surface, creating a tight seal that prevents the escape of fluids. This is achieved through the elastic deformation of the lip material, which conforms to the shaft's surface. As a result, the seal maintains contact even as the shaft moves, effectively mitigating the risk of leakage.

3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.

2. Inspect Parts Examine the internal components for any signs of excessive wear or damage. Identifying all parts needing replacement will ensure a thorough rebuild.
