Linear bearings
Linear motion ball bearings are built with a retainer in the outer ring, with a holder for several steel balls, and for endless circular motion. The spring is fixed at both ends of the retainer, and a notch window is provided on the straight track of the steel ball; this is to provide for the load of the ball and the shaft for rolling contact.
With a very low coefficient of friction relative to the movement, linear motion ball bearings can be used for mechanical equipment, automation equipment, and energy-saving equipment. In these areas, they are the most suitable choice of bearings.
