Inch Size Miniature Flanged Ball Bearings FR4zz

The FR4zz is a miniature flanged ball bearing with a 0.25″ bore and 0.625″ outer diameter, made from sturdy chrome steel. It handles radial loads up to 283 lbf and spins smoothly at speeds up to 38,000 RPM.

Its shielded design keeps dirt out while the stainless steel cage ensures durability. The flange adds stability, making it easier to mount in tight spaces.

This bearing works in temperatures from -86°F to 230°F and requires lubrication for optimal performance. Ideal for small motors, medical devices, or precision instruments where space is limited.

Weighing just 4.9g, it’s lightweight yet robust. Compliant with RoHS and REACH standards for safe use.
