The original Self Contained Oil Type Seal, Scotseal Classic has become the trucking industry standard and the best value for more than 30 years. With literally trillions of road miles to its credit, Scotseal Classic has proven to be a solid choice for dependable, long lasting service. Time and again, field studies show that when properly installed, using SKF tools and procedures, Scotseal Classic is a reliable performer for meeting the sealing requirements between brake maintenance intervals.
SKF Scotseal® Classic is a unitized, one-piece design consisting of a sealing element (packing) that is assembled between a metal outer and inner case. The packing consists of three sealing lips; a spring-loaded primary sealing lip that is factory pre-lubed, a dirt exclusion lip, and an outer bumper lip that acts as a preliminary dirt excluder. The three-lip sealing element is designed to form a reliable seal against the axle. There's no avenue for oil to get out nor for contamination to get in. The seal is press fit into the hub bore using Scotseal Installation Tools. The Scotseal Classic maintains a metal-to-metal contact between the seal O.D. and the hub bore surface as well as a metal-to-metal contact between the packing I.D. and the spindle. The seal O.D. is coated with Bore Tite, which provides a better seal than a simple metal-to-metal press fit.
