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.
Shaft Speed - Considering the speed that the shaft will be moving, the runout, the housing bore and the type of oil being sealed is vital to making sure you select an oil seal that will not suffer from abrasions or spiralling.

Hub oil seals are essential components in automotive and industrial systems, serving to maintain the integrity of the wheel hub assembly. These seals prevent the leakage of lubricating oil and the entry of contaminants, safeguarding the wheel bearings and other internal components. In industrial applications, hub oil seals contribute to the smooth operation and reliability of machinery, ensuring optimal performance and safety.
■Viscosity-index improvers: These additives help your engine oil perform as intended despite temperature fluctuations.

Indeed, when installing this oil seal, the oil sump must be installed using silicone seal. Removal of the old seal and oil sump is necessary, otherwise the oil seal cannot be fitted properly either. If these steps are not followed, leakage is inevitable.
