Metric Size Miniature Flanged Ball Bearings SMF115

Metric Size Miniature Flanged Ball Bearings SMF115

The SMF115 is a small radial ball bearing with a 5mm bore and 11mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 123 lbf and spins at speeds up to 40,500 RPM, making it suitable for high-speed applications.

Its open design requires lubrication but allows for easy maintenance, while the stainless steel cage ensures smooth operation. The bearing works in temperatures from -30°C to 110°C, fitting various environments.

With a compact width of just 4mm and a lightweight 0.81g build, it’s ideal for small machinery or precision instruments. The flange adds stability, helping it stay securely in place during operation.

Compliant with RoHS and REACH standards, it’s a reliable choice for replacements or new designs. Perfect for uses like small motors or delicate devices where space and speed matter.
