The new new Scotseal X-Treme wheel-end seal for trucks and trailers developed by SKF is being touted to offer “superior reliability and high temperature performance,” in addition to its extended five-year/500,000-mile warranty on trucks and 7 years on trailers.
Scotseal X-Treme is the latest addition to SKF's well established line of wheel-end seals for drive, steer and trailer axles: Scotseal Classic, Scotseal Long Life, Scotseal Pro and Scotseal Plus XL. The company said the new seal offers the vehicle service market and OE truck and trailer manufacturers reliability and long life in the harshest of operating conditions.
Scotseal X-Treme offers an extension of the current three-year full parts and labor warranty provided by Scotseal Plus XL to five years for truck and years for trailer applications for the new product under the SKF Trouble Free Operation coverage plans TFO 5 and TFO7 respectively. SKF is able to offer what it calls this “generous guarantee” thanks to new design features that include optimized primary and axial lip profiles, new metal “unitizer geometry” and the use of an upgraded HNBR lip material which enhances the performance of SKF’s unique “wave” lip design.
Collectively, those new features deliver unrivalled under-lip temperatures, lower running friction, improved contamination exclusion and longer seal life, SKF noted.
With a wheel-end seal replacement and hub re-lube taking around two hours, vehicle downtime costs can quickly soar, SKF stressed, but thanks to its new design, Scotseal X-Treme has the potential to cut unscheduled downtime events by half and could drastically reduce wheel-end failure events due to seal problems. The new seal is also designed to cope with the higher temperatures generated by braking systems that are compliant with reduced stopping distance (RSD) rules, the company added, pointing out those seals are available for most standard axle types in a variety of sizes.
