MF Series Flanged Miniature Bearings

The MF Series (Metric Flanged) is a specialized range of ultra-small bearings designed for applications with extremely limited space. Despite their diminutive size, these bearings maintain high precision and low torque. The integrated flange allows for stable mounting in thin-walled housings, making them the preferred choice for micro-electronics, precision sensors, and advanced micro-mechanical assemblies.
