The BBS2001QN represents advanced wheel hub technology, available in both 2nd and 3rd generation configurations to meet diverse vehicle application requirements.
The second-generation hub unit features an outer ring with an integrated flange, eliminating the need for a separate hub . It utilizes a double-row ball bearing design and is typically used for non-driven wheel applications . The outer ring raceways are induction-hardened for improved bearing performance, and the rigid flange comes with threaded holes or studs for brake and wheel mounting . Installation is simplified—simply place it on the axle and secure with a nut.
The third-generation hub unit delivers a higher level of integration, featuring both inner and outer flanges . The inner flange bolts to the drive shaft, while the outer flange mounts the complete bearing assembly . This design is suitable for both driven and non-driven wheel applications . Key advantages include:
1.Fully integrated system that simplifies corner design and handling ,
2.Built-in ABS wheel speed sensors with the magnetic encoder sealed inside the bearing for reliable signal output ,
3.Enhanced load capacity and rigidity, making it ideal for SUVs, off-road vehicles, and 4WD applications ,
4. Modular replacement—simply remove fixing screws to replace the entire unit, reducing maintenance time by up to 60% compared to traditional designs .
The BBS2001QN series combines precision engineering with advanced integration, ensuring reliable performance, simplified maintenance, and enhanced vehicle safety across a broad range of applications.
