Hubs & Bearings, found under Suspension & Steering, are critical components within a vehicle's wheel assembly, connecting the wheel to the axle and allowing for smooth rotation. These parts facilitate both steering and weight support, and are essential for safe and reliable vehicle operation in passenger cars and commercial vehicles. Hub assemblies typically integrate the wheel hub, wheel bearing, and sometimes the ABS wheel speed sensor. Bearings reduce friction between rotating parts, ensuring efficient power transfer and minimizing wear. Examples in this category include Scania hub assemblies (MPN 1856660), MAN wheel hub components (MPN 81.41722-6090 & 85.43715-6013), and Febi wheel bearing kits (MPN 06161). Proper hub and bearing function is vital for maintaining vehicle stability and preventing excessive vibration.
