Abstract:
1. A linear motion bearing assembly, comprising: a) first and second interlocking bearing blocks, each having an inner wall which together define an axial space; b) a load bearing assembly disposed within the axial space of the interlocking bearing blocks, said load bearing assembly including (i) first and second joinable sleeves, (ii) two first load bearing structures disposed within the joined sleeves and each including an inner surface and tracks for ball bearings, and (iii) two second load bearing structures disposed within the joined sleeves and each including an inner low friction surface material which includes one or more of polytetrafluoroethylene, acetal resin, a metal with a dry lubricant selected from graphite, hexagonal boron nitride, and molybdenum disulfide, or a fluid lubricant which comprises a mineral oil, synthetic oil or silicone, said second load bearing structures in sliding contact with a circular shaft, the inner surfaces of said first and second load bearing structures together defining an axial circular channel through which the circular shaft is disposed and linearly and/or rotatably movable therein, with the individual first and second load bearing structures together defining a polygonally-shaped load bearing structure having a circular bore therethrough for receiving the shaft, the first load bearing structures ( the second load bearing structures (
