The first generation of hub bearing units have been delivering top performance and earning top market share for decades. HBU1 was actually developed in the late ¡®60s in response to automotive industry interest in pre-adjusted wheel bearing assemblies.
Today, HBU1 remains our most widely used hub bearing units worldwide. Historically the preferred choice for small-medium car driven wheel applications, Hub Ones are also found in integral drum designs on the non-driven wheels of smaller cars.
Hub bearing unit 1 features a double row angular contact ball bearing with matched rings and ball-sets to provide the required axial clearance. Contact angles are optimized to provide specific preload and withstand specific wheel load condition. Key features include:
Optimized to handle moment loads applied to the bearing during cornering
Cages made from glass fibre reinforced polyamide
Sealed for life with high performance, application-specific grease
Different seal designs available for different wheel bearing arrangements
Available with ABS impulse ring mounted on the rotating ring¡£
