ArvinMeritor Inc has developed Triad, a trailer wheel-end system that features new seals and washers and a patented installation technique designed to achieve extended wheel-end life. This system eliminates maintenance for three years/300,000 miles in on-highway applications. This is incremental to the TB trailer axle series unitized wheel-end program, which provides a five-year/500,000-mile warranty.
The Triad system is offered on TN, TQ, and TP trailer axle models with both ferrous and aluminum hubs, and with lubricants including standard grease and semifluid grease. Triad enables the wheel-end system to achieve proper bearing preload, vent internal wheel-end pressures, and reduce wheel-end contaminant ingress.
This system has the Controlled Position Axle Nut system (C-PAN), supplied by Hub Nut Corp, which prevents interactive bearing/nut abrasion, extends oil seal and roller bearing life, and reduces maintenance time.
