Lip seal HMS series

spring-loadedrubberCR

SKF metric rubber outside diameter radial shaft seals, HMS5 and HMSA10, also called SKF Edge seals as part of the CR Seals assortment, are designed in accordance with ISO 6194-1 and DIN 3760 for use in a wide range of industrial applications. The available size range of HMS5 and HMSA10 seals includes a full coverage of the ISO 6194-1 and DIN 3760 dimensions for shaft diameters up to 250 mm (9.842 in.) as well as an extensive range of dimensions commonly used in the market. New dimensions are continually added. Main features include: Optimized sealing lip material Spring-loaded sealing lip Optimally balanced sealing lip and flex section Beaded outside diameter Auxiliary lip (HMSA10 seals only) Design The rubber outside diameter provides optimized sealing ability in the housing, also at considerable surface roughness or in split housings. The beads on the outside diameter provide improved sealing ability and retention in the bore. They also prevent spring-back during installation. The spring-loaded sealing lip contributes to a quick response in handling dynamic runout and maintaining the sealing performance, even when sealing lip wear is excessive. Sealing lip and flex section are optimally balanced to withstand both high dynamic runout and shaft-to-bore misalignment. The auxiliary lip on HMSA10 seals is non-contacting, which means that the seals normally can operate at the same speeds as the single-lip HMS5 seals.
