SKF HMSA10V Radial Shaft Seal

SKF HMSA10V Radial Shaft Seal is a 40x52x7 mm metric seal designed for use between rotating shafts and their housings, or between components in relative motion, where a compact, robust oil seal is required. It features a rubber outside diameter with a single sealing lip made from fluoro rubber (FKM), and is metal-reinforced for added rigidity, aligning with the HMSA10V specification and its variant’s design. The seal’s 40 mm inside diameter fits modest shaft sizes while its 52 mm outside diameter and 7 mm width define a compact profile suitable for tight housings, and it is described as a radial shaft seal with a rubber outer diameter and a single sealing lip. Typical applications include general industrial equipment such as gearboxes, pumps, and motors where oil containment and contaminant exclusion are critical; SKF data and retailer summaries describe HMSA10V as a seal for oil- and hydrocarbon-containing environments requiring reliable sealing at elevated speeds. Verified operating parameters reported for this seal include a maximum operating temperature up to 200 °C and a permissible rotational speed up to about 10,860 r/min, underscoring its suitability for demanding high-temperature and higher-speed applications in industrial machinery.
