SKF HMSA10 RG Radial Shaft Seal

SKF 100X120X10 HMSA10 RG radial shaft seal is a metric oil seal designed to seal rotating shafts against oil or grease in equipment using a 100 mm shaft and 120 mm housing bore. The RG execution indicates a rubber outer diameter, and the seal uses a single sealing lip made from acrylonitrile-butadiene rubber (NBR) developed by SKF for HMSA10 designs. Its dimensions are 100 mm inside diameter, 120 mm outside diameter, and 10 mm width, matching the 100×120×10 size commonly used in metric shaft-seal configurations. This configuration provides lubricant-retention performance for rotating assemblies in hydraulic and mechanical systems that require a compact, oil- or grease-resistant seal.
