SKF 61740 cr / hms / hmsa radial shaft seal. SKF radial shaft seal for rotating-shaft primary containment against dust, splash and low-head oil pressure. Designation CR / HMS5 / HMSA10 / HMSA10RG (single lip, single lip with dust lip, double lip with garter spring). Elastomer standard nitrile (NBR) to ISO 6194-1 with metal case; hydrogenated nitrile (HNBR), fluoroelastomer (FKM / Viton), silicone (VMQ) and polyacrylate (ACM) available by suffix. Bore, outside diameter and width follow ISO 6194 / DIN 3760.
