A bearing is a machine element that constrains relative motion to only the desired motion, and In the ball bearing and roller bearing, to prevent sliding friction, rolling .. by the machines computerized control, such as PLC or CNC, as well as by manual contact, which creates faults in the outer race, inner race and ball.
Cylindrical roller bearings have moderate thrust loads and high radial-load capacity. Insert bearings and wide inner ring bearings are used for mounting on shafts A machine tool is a machine for shaping metal or other materials, usually by friction of a rotating surface without the need for an inside or outside race.
