Metric Size Miniature Flanged Ball Bearings SMF105zz

Metric Size Miniature Flanged Ball Bearings SMF105zz

The SMF105zz is a small, shielded ball bearing with a 5mm bore and 10mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 74 lbf and spins smoothly at speeds up to 45,000 RPM.

Its shielded design helps keep dust out while maintaining easy access for lubrication. The stainless steel cage and balls ensure long life, even in humid or corrosive environments.

With a compact width of just 4mm and a lightweight 1.38g design, it fits neatly into tight spaces. The flange adds extra stability during installation.

Ideal for small motors, dental tools, or precision instruments where high speeds and reliability are needed. Works in temperatures from -30°C to 110°C and meets RoHS and REACH standards.
