SKF 135X170X12 HMS5 RG Radial Shaft Seal

SKF 135X170X12 HMS5 RG is a metric radial shaft seal engineered for general industrial applications, featuring a 135 mm bore, 170 mm outside diameter, and 12 mm width, designed to sit between rotating shafts and stationary housings while preserving lubrication and preventing contaminants from entering the sealed interface. It uses a rubber outer diameter (RG) and a single sealing lip in the HMS5 configuration, with a nitrile rubber (NBR) lip material optimized for oil- or grease-lubricated systems. The RG designation denotes the rubber outer diameter feature, a common SKF seal design element that helps match shaft-housing clearances, while HMS5 lip geometry provides reliable leakage protection under typical industrial operating conditions. This seal is intended for general industrial equipment where maintaining lubrication and exclusion of contaminants are critical.
