SKF Automotive has announced the industry adaptation of its new Hub Bearing Unit (HBU) wheel bearing. This new HBU has a blend of two different types of rolling bearings in one unit, a unique combination of ball and tapered roller elements.
The design provides increased strength and is 10 percent lighter than conventional wheel bearings. In addition, the HBU Ball/Taper Wheel Bearing features low friction capabilities that deliver a 30 percent reduction in friction compared to current competitive offerings for the same vehicle category. In serial production since 2022, the volume of these ball-taper bearings is moving toward 1 million per year and growing.
The HBU Ball/Taper Wheel Bearing is designed to support the demands of electric vehicle (EV) pick-up trucks and vans, which require low friction and high-speed capabilities. The hybrid nature of this bearing, combining taper bearing and ball bearing elements, allows it to handle increased running milers per battery charge, which aligns with SKF's commitment to environmental sustainability.
SKF Automotive's approach has led to business awards for the new HBU, including a contract in the USA with an initial volume of 1.5 million bearings per year. Additionally, another project has been awarded in Europe for light commercial vehicle applications. The new bearing concept is also gaining substantial traction in the rapidly expanding EV market.
