1. Shape retention and structural support

The metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) provides rigidity and shape stability for the oil seal. During the manufacturing and installation process of the oil seal, the metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) enables the oil seal to maintain a specific shape, such as round, square, etc. This helps the oil seal to be accurately installed in the corresponding position of the equipment, and in the subsequent use process, even if it is affected by certain external factors such as pressure and vibration, it can maintain its basic shape and prevent the oil seal from deforming and causing the sealing performance to deteriorate.

2. Enhanced mechanical strength

Enables the oil seal to withstand greater pressure and mechanical stress. In some high-pressure environments, such as automobile engines and hydraulic systems, oil seals need to withstand higher pressures. Metal skeletons (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) can evenly distribute these pressures to various parts of the oil seal to avoid excessive local stress and cause the oil seal to rupture or damage.

3. Auxiliary seals

The metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) can cooperate with the sealing lip to improve the sealing effect. In the area where the sealing lip of the oil seal contacts the rotating shaft, the metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) can provide a stable support so that the sealing lip can better fit the surface of the rotating shaft and reduce the possibility of leakage.

The metal skeletons (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) of some oil seals are also designed into special shapes, such as with a maze-like structure to further enhance the sealing performance. This structure can increase the path length of fluid leakage, so that the fluid needs to pass through multiple tortuous channels during the leakage process, thereby greatly reducing the risk of leakage.

4. Provide installation positioning

The metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) has structures that are easy to install and position, such as mounting holes, flanges, etc. These structures can be easily connected and fixed with other parts of the equipment to ensure that the oil seal is accurately installed in the predetermined position.

5. Improve heat dissipation performance

The metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) usually has good thermal conductivity, which can help the oil seal dissipate heat. In some equipment that operates at high speed or in a high temperature environment, the oil seal generates heat during operation. The metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) can transfer this heat from the sealing lip and other parts to the outside of the oil seal, reducing the operating temperature of the oil seal, thereby improving the performance and life of the oil seal. For example, in an industrial high-speed centrifuge, the temperature around the oil seal may be very high. The heat dissipation effect of the metal skeleton (also known as Metal frame of the sealing ring,Sealing ring Metal Insert) can effectively prevent the oil seal from accelerating aging or damage due to overheating.
