1. A linear motion bearing assembly comprising:
a rolling element retainer structure, the rolling element retainer structure including a plurality of rolling element retainer segments, each of the rolling element retainer segments including
an inner portion defining at least one rolling element track having an open load bearing portion, an open return portion, and turnarounds interconnecting the load bearing and return portions,a plurality of bearing rolling elements disposed in the rolling element tracks, the rolling elements effective to transmit a load from a shaft to load bearing plates and to facilitate a movement of the linear motion bearing assembly along the shaft, and the load bearing plates positioned axially positioned adjacent to each rolling element retainer structure, the load bearing plates effective to receive a bad from the rolling elements disposed in the load bearing portion of the rolling element tracks; an outer housing sleeve enclosing substantially all of an exposed exterior surface of the rolling element retainer structure, the outer housing sleeve having an inner surface in direct contact with the load bearing plates, the outer housing sleeve being configured and dimensioned to maintain the load bearing plates in position and effective to receive load from the load bearing plates, the outer housing sleeve including
a first sleeve portion including a first number of the rolling element retainer segments; anda second sleeve portion including a second number of the rolling element retainer segments; wherein the first sleeve portion is effective to mate with the second sleeve portion to form the outer housing sleeve, and
the first sleeve portion is mated with the second portion through a protuberance and a hole. |
