SKF · Seals & Gaskets · Radial Shaft Seals — Heavy Industrial
SKF 620X684X25HSS6V hdl / hds / hs radial shaft seal for heavy industrial service. SKF wide-cross-section radial shaft seal for heavy industrial shafts, generally above 200 mm bore. Wider seal face improves fatigue life on paper mills, marine deck machinery, steel mills, cement mills and mining conveyors. Standard elastomer nitrile (NBR) or hydrogenated nitrile (HNBR); FKM available. Full metal case (HS type) or rubberised outside diameter (HMS variants). Dimensioned per ISO 6194 and OEM engineering drawings. Designation follows the SKF alphanumeric identification convention where the numeric block encodes the boundary plan and the suffix declares execution options (material, sealing, cage, precision, clearance, lubricant). Genuine SKF supply carries the SKF logo etch or moulded mark and hologram-authenticated packaging.
