Precessing is a Shafer patented design that takes a full complement of
rollers, and continuously distributes lubrication in an oscillatory application.
By creating a slightly different friction factor from one direction to the
other, the rollers slowly ratchet around the race distributing the lubrication
and reducing wear and fretting.
