Metric Size Miniature Flanged Ball Bearings SF627zz

Metric Size Miniature Flanged Ball Bearings SF627zz

The SF627zz is a compact, shielded ball bearing with a 7mm bore and 22mm outer diameter, crafted entirely from stainless steel for durability. It supports radial loads up to 566 lbf and spins smoothly at speeds up to 27,000 RPM.

Its shielded design helps keep dirt out while retaining lubrication, making it low-maintenance. The stainless steel cage and balls ensure long life even in demanding conditions.

With a flange outer diameter of 25mm, it stays securely in place during operation. Ideal for small motors, fans, or precision instruments where space is limited.

Weighing just 14.4g, it’s lightweight yet robust. Suitable for temperatures from -30°C to 110°C and compliant with RoHS and REACH standards.
