SKF CR 28x40x7 HMS5 V Radial Shaft Seal

SKF CR 28x40x7 HMS5 V is a metric radial shaft seal with a rubber outer diameter and a single sealing lip, designed to seal oil or grease between rotating and stationary components. It measures 28 mm on the shaft bore, 40 mm on the outside diameter, and 7 mm in width, with a fluoroelastomer (FKM) lip material for enhanced chemical resistance and high-temperature performance. The seal’s outer diameter is rubber rather than a metal shell, making it suitable for housings that specify a rubber OD in the HMS5 design family. This configuration is commonly employed in small gearboxes, pumps, and other rotating equipment where a compact, oil- or grease-sealed interface is required to prevent leakage while permitting shaft rotation.
