TROY, Mich. — To help fleets reduce maintenance expenses and minimize vehicle downtime, ArvinMeritor has developed a new trailer wheel-end system, called TRIAD.
The system features new components such as new generation, high performance seals and washers with a patented installation technique designed to achieve extended wheel-end life.
According to the company, this cost-efficient system eliminates maintenance for three years/300,000 miles in on-highway applications. This is incremental to the premium TB trailer axle series unitized wheel-end program, which provides a five-year/500,000 mile warranty.
“This new TRIAD system is a real advancement for our customers due to its high-performance and cost-saving advantages,” says Jim Grant, chief engineer for trailer axle products.
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 system has the Controlled Position Axle Nut System (C-PAN), supplied by the Hub Nut Corporation, which prevents interactive bearing/nut abrasion; extends oil seal and roller bearing life; reduces maintenance time; and assures improved tire wear, according to ArvinMeritor.
