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 conformance.
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.
