Bearing Units with Integrated Flanges, A Contribution to Modern Commercial Vehicles

Flange Bearing Units increasingly become interesting as wheel bearings of truck front axles, as wheel bearings of trailer axles, as final drive pinion bearings. These Bearing Units integrate the functions of

• 2 pre-adjusted single bearings
• the seal package
• the lubrication system
• the attachment flanges
• the pulse ring, if ABS is applied.

Dependent on the dimensions, 2 designs of Flange Bearing Units have been developed for trucks, the Fully Integrated Unit and the Insert Unit.

This paper itemizes the advantages to the user of these Flange Bearing Units, advantages concerning the assembly line, the service life, the maintenance of the component or of the vehicle.
