HMS5 and HMSA10 seals
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)
Material
The optimized nitrile rubber compound used for the HMS5 and HSMA10 seals has the designation suffix RG. The compound is the result of long experience and the latest findings from the SKF seal material developments. Advantages of this material include:
- good resistance to ageing
- very good pumping ability
- good wear resistance
Applications and operating conditions
HMS5 and HMSA10 seals are designed for oil or grease lubricated applications with operating temperatures ranging from –40 to +100 °C (–40 to +210 °F), short-term up to 120 °C (250 °F). These seals are also appropriate for sealing lubricants within a wide range of viscosities.
