SKF CRW1-H 550989 is a metal-cased rotary shaft seal sized 70 mm inside diameter, 90 mm outside diameter, and 10 mm wide, engineered to seal oil or grease between a rotating shaft and its housing. This CRW1-H variant uses a Hydrogenated Nitrile Rubber (HNBR) lip and a Wave lip design inside a metal housing with a sealant-coated finish for durability in demanding environments. It is intended for oil and grease sealing between rotating and stationary machine components in relative motion, with typical applications in pumps, gearboxes, and other power-transmission assemblies where a rotating shaft passes through a housing.
