    The reinforced, all-rubber HSS seals offer mills a high-performance solution that increases reliability and productivity.

    Gothenburg, 7 October 2013: SKF is launching the HSS seals for the metals industry, the company's most recent addition to its line of industrial radial shaft seals. HSS seals offer rolling mills a reliable and easy-to-install solution for mill stand chocks. This seal range features a new concept of seal reinforcement and is SKF’s new preferred offer for large size bearing protection in metal-making assets.

    “Seals are often perceived as commodity items. In reality, they are essential system components that help to ensure bearing and system performance, reliability and efficiency. When installed as part of an optimized bearing arrangement, HSS seals offer mills a solution to upgrade asset performance, boost overall mill reliability and productivity, and cut costs per tonne”, says Robert Blachfellner, SKF Global Product Manager Industrial Seals Segment.

    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. 

    HSS seals can be customized to match specific shaft and seal housing dimensions without additional costs or extended delivery times.
