Ball bearings of this size are ideal for precision work and applications that require a lot of functional mechanical parts in a small space, such as 3D printer, quadcopter or model.

Features:

These miniature bearings are made of high quality bearing steel for low noise and long service life.

They are double shielded to avoid contaminants entering and save lubricant.

Bearings have a 4mm inner diameter, a 9mm outer diameter, a 4mm thickness and a 10.3mm flange.
