688zz bearing Mini Metal Double Shielded Flanged Ball Bearing For 3D Printer Parts-PC Friend 688zz 5*16*5 mm. The main purpose of the ball bearing is to reduce the rotational friction and support radial and axial. It is because of the smaller contact area between the balls and racesBall bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings . However, they can tolerate some misalignment of the inner and outer loads.
