Metric Size Miniature Flanged Ball Bearings SF683zz

The SF683zz is a small, shielded ball bearing with a 3mm bore and 7mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 54 lbf and spins at speeds up to 56,700 RPM, making it suitable for high-speed applications.

Its shielded design helps keep dust out while maintaining smooth operation, and the stainless steel cage ensures long-term reliability. The bearing requires lubrication for optimal performance and works in temperatures from -30°C to 110°C.

With a compact width of just 3mm and a lightweight 0.53g build, it’s ideal for small devices like precision instruments or miniature motors. Compliant with RoHS and REACH standards, it’s a safe and practical choice for various uses.

The flange design adds stability, making installation easier in tight spaces. Its ABEC1 tolerance and MC3 radial clearance balance performance and affordability for everyday needs.
