- Oil seals are also designed to keep contaminants out of the system. Dirt, dust, and other debris can enter the system through various routes, such as open bearings or worn seals. These contaminants can cause damage to the moving parts and reduce the efficiency of the machine. Oil seals help to prevent this by creating a tight seal that keeps contaminants out.

In conclusion, oil seals are critical components in ensuring the proper functioning of machinery and equipment. By selecting the right seal based on material, design, size, and operating conditions, users can prevent oil leaks, reduce maintenance costs, and prolong the life of their equipment. With a wide range of options available, it is essential to choose a high-quality seal that meets the specific requirements of the application.

Helix Seal
Seals are designed to create a tight seal around the shaft by utilising a combination of lip geometry, surface tension, and lubrication. When the shaft rotates, the lip of the oil seal comes into contact with the shaft surface, creating a frictional force that generates heat. This heat helps to soften and conform the elastomeric material of the oil seal to the shape of the shaft, ensuring an effective sealing action.

Auto parts oil seals play a crucial role in the proper functioning and maintenance of vehicle systems. These seals are designed to prevent the leakage of lubricating oil and the ingress of contaminants, ensuring the integrity and efficiency of various components within the vehicle. From wheel hub oil seals to steering oil seals, these components are essential for the smooth operation and longevity of automotive systems.



The major cause of extrusion and nibbling is stress caused by high pressure. This is commonly noticed when the oil seal has a chipped or nibbled look. In fact, in some cases, the surface of the seal tends to peel on its own, which makes it have a shaved look. What the stress does is that it increases the clearance gap between the mating edges, which causes the seal to get entrapped, and then leads to severe physical damage.
