Seals for large size bearings in rolling mills

SKF has introduced HSS radial shaft seals for the metals processing industry. Offering rolling mills a reliable and easy-to-install product for mill stand chocks, this seal range features a new concept of seal reinforcement.

HSS seals are available in nitrile rubber (NBR) and the two SKF developed materials SKF Duratemp (HNBR) and SKF Duralife (FKM), which have been successfully used for decades in demanding applications.

The standard grade of these high-performance materials is used for the sealing lip, while the part of the seal body contacting the housing bore is made from a harder grade to provide improved stability in operation and during installation.

This concept of reinforcing the seals allows split designs, which facilitates installation and replacement. The smooth outside diameter provides excellent static sealing and there is no risk of dimensional changes to the seals when exposed to moisture.

HSS seals also feature optional grease ports in the back that allow re-greasing between the sealing lips in back-to-back or tandem installations of two HSS seals in the application. They can be customised to match specific shaft and seal housing dimensions without additional costs or extended delivery times.
