Metric Size Standard Miniature Ball Bearings 626

The 626 is a compact miniature ball bearing with a 6mm bore and 19mm outer diameter, crafted from sturdy chrome steel. Its slim 6mm width makes it ideal for tight spaces while handling radial loads up to 447 lbf.

With a maximum speed of 32,000 RPM, it spins smoothly for small, fast-moving applications. The open design allows easy lubrication, and the stainless steel cage ensures durability.

This single-row bearing suits general-purpose use where moderate loads are expected. It works reliably in temperatures from -30°C to 110°C.

Weighing just 8.12g, it’s a lightweight choice for devices like small motors or precision instruments. Compliant with RoHS and REACH standards for safe operation.
