5, the oil seal is easy to dismantle and inspection is convenient.
Polyacrylate
Better heat, oil and chemical resistance than NBR
It is recommended for use in oil which contains load bearing additives such as EP gear oils
PTFE is special in that a pre-tensioned spring is not required. This is because the material returns to its original shape when heated, also known as the shape-memory polymers (SMPs) effect. These oil seals are also supplied as integrated parts, where it only needs to be installed as one component.
3, the oil seal installation position is small, axial small size, easy processing, and make the machine compact.

A: Existing molds: 30 days, depending on ordering quantity.
Another factor you need to consider is the type of lubricants that are more suitable for the seals. Check for the appropriate viscosity of the lubricant that’s compatible with the seal material.
ERIKS type M (type B according to the DIN standard) has a single metal casing and rubber sealing lip. Since the casing is made of metal, it must be fitted in a well-finished, undamaged groove. Large volumes of oil seals with metal casings are often cheaper, which is why they are often used as original equipment in machines. However, if an oil seal has to be replaced, types with a rubber exterior (type R or RST) are easier to fit. Type MST is similar to M and commonly used. The difference is the dust lip in the MST oil seal that prevents dust and dirt reaching the sealing lip, and extends its service life in dusty environments.


In conclusion, the 38x52x7 oil seal is an essential component in many types of machinery, providing reliable protection against oil leakage and helping to extend the life of mechanical components. By selecting the right seal for the application and ensuring proper installation and maintenance, you can help to ensure the efficient and reliable operation of your machinery.
When it involves a repair, you must first remove the old oil seal. To remove an oil seal, it is important to use the right tools to avoid damaging the shaft and bore. The best solution is therefore to pull out the oil seal without having to completely dismantle the shaft. This can be done by making a few holes in the oil seal with an awl and a hammer. You can then use a hook to pull the oil seal out of its seat. You could also screw some screws into the holes and then slowly pull out the screws to extract the oil seal from its housing. Be careful not to damage the shaft or housing in the process.
