Product features:
The MH-P16 ACB4052 headset bowl ball bearing, tailored for bicycle headsets, adopts small-outer-diameter steel balls to achieve low friction torque—ensuring
smooth, effortless steering during rides. It also boasts high rigidity, capable of withstanding the combined radial and axial loads from steering operations and
road impacts, while delivering excellent rotation accuracy for stable performance even after long-term use.
Optimized for bicycle headset layouts, this bearing features a thin-walled structure that creates an extremely slim bearing section. This design not only fits
seamlessly into the compact space of bicycle headsets but also contributes to the miniaturization of the headset system and the overall lightweighting of
the bike, enhancing riding efficiency and comfort.
