In addition to their main function of sealing and protecting machinery, rotary shaft oil seals also play a crucial role in improving the efficiency and longevity of the equipment

rotary shaft oil seals. By reducing the amount of oil leakage and contamination, oil seals help to maintain the optimal performance of the machine and extend its service life. This, in turn, leads to cost savings for the operator by reducing maintenance and repair costs.

This particular oil seal is designed to accommodate a shaft diameter of 50mm while sealing against a housing with an outer diameter of 90mm, ensuring tight closure and effective sealing. The 10mm width is optimal for creating a sufficient sealing surface to prevent leakage while maintaining a low profile in installations.

70 90 10 oil seal. Advanced materials and refined designs have led to the development of oil seals that approach the 70% efficiency threshold under extreme conditions, marking a notable achievement in mechanical seal technology.


One of the main signs that a wheel hub seal needs to be replaced is the presence of grease around the wheel hub. If you notice grease leaking from the wheel hub area, it is likely that the seal is worn out and needs to be replaced. Another common indication that the wheel hub seal is damaged is the presence of a grinding or squeaking noise when driving

wheel hub seal. This noise is caused by the lack of lubrication in the wheel hub, which can lead to metal-on-metal contact and damage.
