Wheel bearings for heavy trucks

Hub Unit Offset Design

The Hub Unit Offset Design is used for applications with brake disks of flat design in front, rear and trailer axles. Insert bearings (as previously described) are used for this version. These insert bearings are assembled in a specially developed spheroidal graphite cast iron hub in fully-automated large hub assembly lines at FAG (locations: Berndorf, Austria and Jeonju, South Korea).

As an option, FAG can also mount the brake disk of flat design on the hub and supply the wheel end with the brake disk as a complete unit.

The units are normally also fitted with ABS pole wheels. These bearing units are greased and sealed for life and operate under preload. They are maintenance-free and have a life of over one million kilometers.
