Metric Size Miniature Flanged Ball Bearings SMF137zz

Metric Size Miniature Flanged Ball Bearings SMF137zz

The SMF137zz is a small, shielded ball bearing with a 7mm bore and 13mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 93 lbf and spins at speeds up to 36,000 RPM, making it suitable for high-speed applications.

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

With a compact width of just 4mm and a lightweight 2.17g design, it’s ideal for small machinery or precision instruments like dental tools or miniature motors. The flange adds extra stability during installation.

Compliant with RoHS and REACH standards, this bearing is a reliable choice for environments where corrosion resistance and cleanliness are important. Its ABEC1 tolerance ensures consistent performance for everyday industrial needs.
