ArvinMeritor introduces TRIAD wheel-end system
ArvinMeritor
ArvinMeritor’s latest trailer wheel-end system, called TRIAD, is designed to be maintenance-free for three years/300,000 miles in on-highway applications. The TRIAD system — available on TN, TQ and TP trailer axle models with both ferrous and aluminum hubs, and with various lubricants including standard grease and semi-fluid grease — enables the wheel-end system to achieve proper bearing preload, vent internal wheel-end pressures, and reduce wheel-end contaminant ingress, the company says.
The system has the Controlled Position Axle Nut System (C-PAN), supplied by the Hub Nut Corp., which prevents interactive bearing/nut abrasion; extends oil seal and roller bearing life; reduces maintenance time; and assures improved tire wear.
TRIAD will be supplied to original equipment trailer manufacturers in North America. The maintenance-free claim is incremental to the premium TB trailer axle series unitized wheel-end program, which provides a five-year/500,000-mile warranty.
