M4 Ball Bearings
A ball bearing is a type of rolling-element bearing that uses spherical balls to maintain separation between two concentric rings, called races, allowing for smooth relative motion between machine parts while minimizing friction. The primary function of a ball bearing is to reduce rotational friction and support both radial (perpendicular to the shaft) and axial (along the shaft) loads. It achieves this by using at least two races to contain the balls and transmit the loads through them: typically, one race is fixed while the other rotates with the shaft or hub
