SKF 401991 — V-Ring axial seal
SKF · Seals & Gaskets · V-Ring Seals
SKF 401991 v-ring axial seal. All-rubber axial seal (V-ring) that rotates with the shaft and seals against a stationary counterface, protecting the primary shaft seal against splash water, dust and mud on marine deck machinery, agriculture and construction equipment. Stretch-mount over the shaft — no housing bore required. Standard nitrile (NBR); FKM for high temperature. 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.
