Linear bearing is a linear motion system with high precision, low cost and low friction resistance. The linear bearing is a direct acting system combined with the guide shaft to realize infinite linear motion by using the rolling motion of the ball. The linear bearing is equipped with a steel ball cage in the outer ring, the cage is equipped with multiple rolling balls, and the ball makes infinite circular motion. Both ends of the cage are fixed with sealing gasket retaining rings, and notch windows are set in the linear track direction of each steel ball under force. This part makes the loaded steel ball make rolling contact with the shaft and move relatively with a very low friction coefficient.
Therefore, linear ball bearing is the most suitable bearing for mechanical equipment, automation equipment, energy-saving equipment and so on
