Hendrickson unveiled new wheel-end systems including the first new trailer hub/spindle design in more than 40 years — the HNP hub and P90 spindle.
Hendrickson said its HNP and HUS wheel-end systems are designed to launch a new era of suspension assemblies when combined as an option with INTRAAX primary and VANTRAAX slider systems. HNP comes with a five-year limited warranty and HUS provides a seven-year limited warranty.
“In addition to delivering weight savings, durability and outstanding performance, HNP and HUS wheel-end systems provide complete system integration from axle through wheel end and feature the advantage of a single warranty source,” said Jeff Shahan, program manager, Hendrickson Trailer Suspension Systems. “With today’s haulers striving for minimal maintenance in wheel ends, Hendrickson continues to develop solutions to meet their needs for improving performance and minimizing operating costs.”
The HNP wheel end utilizes ADI (Dura-Light) material, designed to be durable and lightweight. Installed by Hendrickson’s factory-trained technicians, HNP incorporates twin “N” inner bearings, an “R” seal, a patent-pending spindle nut system and a patent-pending self-centering hubcap for a complete rebuildable wheel end.
The tapped hole in the hubcap allows attachment of an alignment tool or hubodometer without jeopardizing the integrity of the hubcap seal, the company said. The wheel end reduces maintenance and helps increase uptime by eliminating seal and bearing replacement every 250,000 or 500,000 miles.
Factory installation of both HNP and HUS systems achieves an advanced bearing setting and locks out contaminates from the assembly process to increase bearing life and help reduce bearing maintenance, the company said. Hendrickson’s patented axle filter is designed to provide additional protection from contaminates.
For haulers adopting today’s wide-base tire configurations, the P90 spindle gives fleets the choice to use either wide-base or dual tires. This 90mm parallel spindle also promotes even lubrication for the bearings.
The HNP and HUS systems accommodate both the zero-offset and two-inch outset wheel-end applications for wide-base tires as well as duals, the company said.
