Aftermarket Hub Bearing Kit 498 625 B/4e0 407 625b Wheel Hub Bearing A6 A8 (4F2/4D2/4F8) Good Quality

Durability & Material

#55 carbon steel offers reliable durability with its medium-carbon composition (0.52-0.60% C), providing excellent wear resistance and structural stability.

Through proper quenching and tempering treatment, it achieves an optimal balance of hardness (HRC 52-55) and toughness, making it particularly suitable for automotive bearing applications where consistent performance under moderate loads is required.

The material maintains its mechanical properties through extended service life while remaining cost-effective for mass production.

Precision machining adaptability

CNC grinding ensures that the roundness error of the inner and outer rings of the bearing is small, matching the tolerance of the hub groove of mainstream models.

Dynamic balancing correction to reduce high-speed driving vibration.

Cost-effectiveness

The material cost is 30%~40% lower than that of bearing steel (such as GCr15), which is suitable for mid-end aftermarket and bulk purchasing needs.

The rust resistance can be improved by zinc-nickel plating (10μm) or phosphating treatment, balancing performance and price.

Traceabilit

Compatible with ISO 9001 and IATF 16949 systems, meeting the requirements of second-tier suppliers of mainstream OEMs.
