The core feature of this product series is an integral flange on the outer ring. This design effectively resolves the issue of axial positioning within the mounting bore. Manufactured from high-quality bearing steel, the flange ensures resistance to deformation under axial thrust loads. The material provides exceptional hardness, maintaining high bearing rigidity even in miniaturized designs. Precise calibration of the perpendicularity between the flange face and the outer diameter ensures that the bearing's centerline remains perfectly perpendicular to the mounting surface after installation, thereby minimizing eccentric wear.
Bearing Features
These miniature flanged bearings are particularly well-suited for precision devices featuring thin-walled housings or space constraints; by reducing the number of auxiliary positioning components, they not only shorten assembly times on the production line but also lower the overall Bill of Materials (BOM) cost.
