Metric Size Miniature Flanged Ball Bearings SF679zz

Metric Size Miniature Flanged Ball Bearings SF679zz

The SF679zz is a small, shielded ball bearing with a 9mm bore and 14mm outer diameter, crafted entirely from stainless steel for durability. It handles radial loads up to 158 lbf and spins smoothly at speeds up to 32,400 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 compact width of just 4.5mm and a lightweight 2.2g design, it fits neatly in tight spaces. Ideal for small motors, dental tools, or precision instruments where reliability matters.

Operates in temperatures from -30°C to 110°C and meets RoHS/REACH standards. Requires lubrication for optimal performance.
