Abstract

The present invention is an improved linear recirculating bearing assembly and method of making it. More particularly, the present invention is a linear roller bearing assembly in which the housing is manufactured of three primary parts, an upper bearing half, a race member and a lower bearing half. The race member includes one or more mounting pedestals having an upper surface finished to a high degree of flatness and parallelism with the lower surface of the race member. The upper bearing half and the lower bearing half include portions to define two recirculating bearing paths for recirculating bearing elements or rollers to recirculate about paths around the race member, with the upper and lower bearing halves being generally non-load bearings, so that they may be manufactured from low cost, low strength materials.
