F67 Series Thin-Wall Flanged Bearings

The 67 series represents a lightweight option within the thin-section bearing category. Its cross-sectional dimensions are exceptionally small, pushing the boundaries of bearing manufacturing technology. Given the minimal wall thickness, traditional fastening methods can easily cause deformation; the integrated flange, however, provides a secure means of axial location. This series is primarily utilized in robotic joints, drone gimbals, and precision semiconductor equipment.

Bearing Features

Manufactured from high-purity bearing steel, the bearings maintain sufficient structural rigidity despite their thin-walled design. Their extremely low running resistance helps extend the battery life of the equipment. With superior precision ratings capable of achieving micron-level repeatability, they are the preferred choice for modern, compact designs.
