SKF
Scotseals for Truck Wheel Ends
SKF Scotseals are the premium, high-performance cassette seals specifically engineered for the most demanding truck, trailer, and bus wheel end applications. The Scotseal design features three sealing lips, an integrated wear sleeve, and a labyrinth passage all within a single, easy-to-install cartridge. The outer rubber element provides a tight bore seal and allows minor bore imperfections. The inner wear sleeve provides a pristine running surface, independent of the axle spindle condition. Scotseals are offered in various models (e.g., Scotseal Classic, Scotseal XL) for oil or grease lubrication, with specific compounds for high-temperature or synthetic oils. The Scotseal is the go-to seal for fleets seeking maximum wheel end protection, extended service intervals, and roadside failure reduction. Its proven track record has made it synonymous with reliable truck wheel sealing.

Why Scotseal Long‑Life Is the Standard for Extended Service
The Long‑Life version uses HNBR lips that resist the higher temperatures of disc‑brake axles and the aggressive additives in synthetic hub oils. Extended‑drain hub oils demand a seal that does not degrade over 300,000+ km. Scotseal Long‑Life meets this demand, supporting the industry trend toward fewer shop visits.
Scotseal XL: Extra Protection for Severe‑Duty Axles
Logging, mining, and heavy‑construction trucks operate in deep mud and water. The Scotseal XL adds a fourth, axial‑type lip and an enhanced labyrinth, providing a tortuous path for contaminants. Even when submerged, the seal keeps the bearing completely dry, a feat unmatched by single‑lip designs.
