Metric Size Miniature Flanged Ball Bearings SMF52

Metric Size Miniature Flanged Ball Bearings SMF52

The SMF52 is a small radial ball bearing with a 2mm bore and 5mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 29 lbf and spins at impressive speeds up to 76,500 RPM.

Its open design and ABEC1 tolerance ensure smooth operation, while the stainless steel cage adds strength. The bearing requires lubrication for optimal performance and works in temperatures from -30°C to 110°C.

With a compact width of just 2mm and a lightweight 0.19g build, it fits snugly in tight spaces. The flange design (6.2mm outer diameter) helps keep it securely in place during high-speed use.

Ideal for precision devices like small motors or dental tools where space and speed are key. Compliant with RoHS and REACH standards for safe use in various applications.
