Description
Ensure flawless high-speed tracking and maximum radial load handling for your commercial car carrier with this premium replacement outer wheel bearing cone.
The Traction Part Number 28682 (interchanging with Dexter factory code 031-021-02) is a high-capacity tapered roller bearing cone engineered explicitly for maximum-duty commercial utility trailers. Manufactured from high-alloy steel, this individual inner race assembly contains precision-ground rollers and a stamped steel cage. The separable design allows for uniform distribution of massive axial and radial forces across the hub assembly, drastically minimizing structural friction, reducing operating heat, and eliminating dangerous wheel-end vibration during long-haul auto transport routes.
