[Application Features] FZH copper base ball cage, is a copper alloy matrix, and on its outer surface, processed orderly, proper size, shape, special hole in its cavities insert Ball Rolling . Circumferential grooves orifice using the latest technology lock ball, effectively solves the traditional ball-point lock and lock the ball indentation can not completely prevent the ball off the problem. Bottom of the hole machined 90 ° spigot makes copper ball in the hole to rotate freely without falling. Since the ball diameter is greater than the wall thickness of the retaining ring, so when using the ball above the holding circle, the outer peripheral surface, in direct contact with the mating bore and the shaft, the base member (retainer) floating in the middle, and Matching the difference is less than the radius of the hole and shaft diameter steel balls, which co-ordinated with the ball for the interference fit, with high accuracy, flexible shaft and bore relative motion. A retaining ring replacements. 1. Bushing: material GCrl5, YB9, heat treatment, hardness HRC62 ~ 66, according to technical conditions GB / T12446 and the shaft with 0.01 to 0.02 should have radial interference, the surface roughness of 2 axes: material GCrl5, YB9, heat treatment, hardness HRC62 ~ 66, according to technical conditions GB / T12446, tolerance of the shaft using h5, surface roughness 3. Measure: Use common measurement tools (pneumatic measuring instrument, dry-foot outside diameter, inside diameter dial gauge, etc.) size deviation measurement axis bushings and ball, and you can find the amount of interference fit after that Ymax = dmax + 2d'-Dmin, require the amount of interference is 0.01 ~ 0.02mm.
