A recent addition to SKF’s line of industrial radial shaft seals is the range of HSS seals for the metal industry. HSS seals offer rolling mills a reliable and easy to install solution for mill stand chocks. They feature a new concept in seal reinforcement and are SKF’s preferred choice 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 optimised bearing arrangement, HSS seals offer mills a solution to upgrade asset performance, boost overall mill reliability and productivity, and cut costs per ton,” says Robert Blachfellner, SKF global product manager, industrial seals segment.
HSS seals are available in nitrile rubber and two SKF developed materials, SKF Duratemp and SKF Duralife). These have been successfully used for decades in demanding applications. The 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. The seals can be customised to match specific shaft and seal housing dimensions without additional costs or extended delivery times.
