SKF 150X180X15 HMS5 RG Radial Shaft Seal

SKF 150X180X15 HMS5 RG is a radial shaft seal designed for general industrial applications, delivering a compact, robust barrier for rotating shafts in gearboxes, pumps, and other machinery where reliable lubrication retention and contamination exclusion are essential. In the HMS5 RG family, the seal uses nitrile rubber (NBR) as the lip material and is built with a rubber outside diameter, featuring a single sealing lip and no auxiliary lip, which simplifies installation while providing dependable dynamic sealing. Its precise dimensions are 150 mm shaft diameter (ID), 180 mm outer diameter (OD), and 15 mm nominal width, classifying it as a standard HMS5 RG size and aligning with SKF's cataloged offerings for large-diameter sealing needs. The RG designation indicates the rubber-outside-diameter construction, a common configuration for oil-seal variants intended to seal on rotating shafts against oil or grease in lubricated systems. SKF and major distributors list this model among their radial shaft seals for general industrial use, making it a widely-available option when a straightforward, economical, large-diameter seal is required.
