Ball cages are manufactured from a heat treated aluminum alloy which provides tough,wear resistant qualities.The ball bearings are vacuum degassed quality,fatigue resistant steel and are inspected to ensure roundness,smoothness and dimensional confommance.
The ball bearings are arranged in the cage in a spiral pattern to minimize tracking or grooving and assure uniform wear.Ball cages are mounted to drilled and tapped guide posts by a special washer assembly which permits the cage to rotate freely around the guide post when not under pre-load.
