The 69 series features a greater width and cross-sectional thickness than the 68 series, delivering superior rigidity and service life within its class. Its flanged design further enhances performance in environments characterized by high speeds and high-frequency vibrations. Favored in applications such as light industrial automation, high-end fitness equipment, and bicycle bottom brackets, the 69 series is prized for its excellent resistance to bending moments.
Bearing Features
The high elastic modulus of the bearing steel ensures consistent rotational accuracy even under alternating loads. By saving radial installation space and simplifying axial retention through its flange, this bearing series offers an ideal solution for industrial designs that prioritize both high performance and lightweight construction.
