Metric Size Miniature Flanged Ball Bearings SMF63 2rs

Metric Size Miniature Flanged Ball Bearings SMF63 2rs

The SMF63 2RS is a compact radial ball bearing with a 3mm bore and 6mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 36 lbf and spins remarkably fast, reaching speeds of 63,900 RPM.

Its sealed design with nitrile rubber shields keeps dirt out and grease in, making it low-maintenance. The stainless steel cage ensures smooth operation even at high speeds.

This bearing is ideal for small, high-speed devices like miniature motors or precision instruments. Its lightweight design (just 0.26g) makes it perfect for applications where every gram counts.

Operating smoothly from -30°C to 110°C, it meets RoHS and REACH standards for safe use. The flange adds stability, making installation easier in tight spaces.
