PreSet Plus hub assemblies from Consolidated Metco (ConMet) will be standard on all Peterbilt Class 8 trucks manufactured at its Denton, TX, plant, beginning in July.

“Peterbilt trucks have always been at the forefront of product technology and innovation,” explains Bill Kozek, Peterbilt general manager. “ConMet’s PreSet Plus hub assemblies support that tradition by insuring our trucks are equipped with the most advanced wheel ends on the market.”

PreSet Plus hub assemblies feature ConMet Premium bearings, which offer:

  • A 40% improvement in surface finish that results in superior rolling contact, reduced friction, lower operating temperatures and increased lubrication.
  • Precisely engineered profiles minimize raceway and roller stresses under heavy loads and better utilize the roller length under light loads
  • Increased bearing life even when used in demanding conditions such as wide-base single wheels and misalignment due to spindle wear.

PreSet Plus hubs offer an integrated spindle nut that simplifies installation, protects components during installation and removal, and aids in removal of the assembly during service. They also have a patented nut system that increases clamp to improve safety and eliminate adjustments required to engage a locking ring, and a new bearing spacer that has been optimized for the PreSet Plus system to accommodate higher clamp loads.

“We wanted to set the bar even higher when it comes to wheel hub technology,” explained Mark Wagner, VP of Wheel Ends for ConMet. “PreSet Plus provides Peterbilt with a product that is easier to install than conventional hubs and is easier for technicians to service.”

All components are field serviceable, the bearings are pre-adjusted, and they include a long life oil seal and magnetic fill plug on drive and trailer hubs for inspection of metal particles in lubricant.
