High Precision Corrosion Resistant Steel-Ball Retainer Cage Bushing For Punching Machine
Product Description:
ABC-BSB. steel balls are held in place. Copper alloys, hard aluminum alloys, and POM resins are used as substrates, and they are arranged on the outer surface of the steel balls in an orderly manner. The appropriate size and shape of the special hole, in its hole embedded in the rolling bearing steel ball. The use of the latest groove circumferential locking ball technology effectively solves the problem that the traditional lock ball and the indented lock ball cannot completely prevent the ball from falling off. The bottom of the hole is machined 90° the stop allows the steel ball to rotate freely within the hole without falling off. Since the diameter of the steel ball is larger than the wall thickness of the retaining ring, the steel ball is used to maintain the inner and outer circle surfaces of the ring when in use, and directly contacts the matching hole and the shaft, so that the substrate (holding ring) floats in the middle, and the matched The difference between the hole and the shaft radius is smaller than the diameter of the steel ball, that is, the steel ball cooperates with it to be an interference fit, and the matching accuracy is high, and the relative movement of the shaft and the hole is flexible. Is to keep the circle of replacement products.
Advantage
The traditional hole and shaft with relative movement have a certain gap, and the coefficient of friction between the hole and the shaft is large. After the steel ball is used to hold the ring, the shaft and the hole are not in direct contact with each other; Steel ball, so high movement accuracy, rolling friction instead of dynamic friction, rolling flexibility, low friction coefficient, long service life, in the case of both rotating and moving, with oil-free or refueling shaft sleeve and shaft, although Satisfy, but the movement accuracy is low, with rolling bearings, can only meet the relative rotation of the shaft, and the ball to maintain the circle, the above two conditions are met, has been widely used in cold die rolling mold, high-precision machine tools, Machine accessories and high-precision axial or axial simultaneous radial movements.
