A ball bearing is a type of bearing that uses balls to reduce friction and support radial and axial loads. Ball bearings consist of an inner ring, an outer ring, and a number of balls that are held in place by a cage. The balls are made of steel or ceramic and roll between the inner and outer rings, reducing friction and allowing the bearing to rotate smoothly. Ball bearings are used in a wide range of applications, from automobiles and machinery to household appliances and sporting equipment.
Properly installing ball bearings in a 3D printer or CNC machine is essential for ensuring smooth and precise movement, as well as prolonging the life of the bearing. Here are a few steps to help ensure proper installation of ball bearings:
