STEMCO Introduces Trifecta™ Pre-Adjusted Hub Assembly

STEMCO, an EnPro Industries company (NYSE: NPO) and leading manufacturer of heavy-duty components and solutions for commercial vehicles, is pleased to introduce the Trifecta™ Pre-Adjusted Hub Assembly. The new wheel end system was developed in partnership with Webb Wheel Products, a technological leader in quality wheel end hubs and drums.

Designed for safety, performance and confidence, the STEMCO Trifecta Pre-Adjusted Hub Assembly features the industry-first Discover® XR (extreme runtime) wheel seal with GlideLock™ technology. The seal glides on and is self-locking, reducing installation force by 50%, with no prelube required—a first of its kind in the industry. The combination of the Discover XR wheel seal, Webb Wheel’s hub and the Defender composite hub cap provides the industry’s best contamination and corrosion resistance.

The Trifecta assembly also features STEMCO’s Zip-Torq® fully unitized axle spindle nut, increasing simplicity and safety for end users. There are no additional clips, keepers, snap rings or screws to install. The self-ratcheting locking feature prevents inadvertent back-offs.

Additionally, installation of the new hub assembly requires no bearing adjustment, ensuring the hub is installed correctly, quickly and easily. STEMCO manufactured components ensure simpler, faster wheel end maintenance.

“Trifecta is the latest innovation to combine safety, performance and confidence into one complete package,” explained Mark Holley, segment business leader of wheel end products for STEMCO. “By combining STEMCO manufactured products with patented technology, the assembly is uniquely developed to extend wheel end life while providing unmatched contamination prevention. Matched by a long-life, five-year/500,000-mile warranty for on highway applications, Trifecta is a solution that meets the increasing performance expectations of today’s fleets.”
