Bearing - Standard Deep Groove Ball Steel Bearing ABEC-5

A ball bearing is a small, round object that helps things move smoothly. It is important for 3D printers, because it helps the x, y, and z axes move smoothly. Most ball bearings are ABEC-5, which is good enough for 3D printing. Lubricating oil inside the bearing also protects it from over spinning. A small piece of plastazote, plastic foam, is used to make the bearing more accurate. The foam acts as a “spacer”, helping the inner race and outer race stay together.

All in all, it is a very complex mechanism with many moving parts that are precisely machined. If a ball bearing goes bad, or breaks, your printer will be very loud, the z axis will move up and down erratically, and prints will fail.
