SKF 125X150X12 HMSA10 RG is a radial shaft seal designed for oil- or grease-lubricated rotating shafts, built around a 125 mm shaft diameter, a 150 mm housing bore, and a 12 mm cross-section. The HMSA10 design uses RG lip material, acrylonitrile-butadiene rubber (NBR) developed by SKF for this seal family. This variant is described as a double-lip oil seal with a nitrile rubber lip, optimized for reliable sealing in medium-sized machinery. It is marketed for general industrial applications, including pumps and gearboxes, where a 125×150×12 seal is required.
