Abstract
A linear motion rolling contact guide unit includes a guide rail, a slider and a plurality of rolling members interposed between the guide rail and the slider. The guide rail is formed with a pair of upper inner guide grooves and a pair of lower inner guide grooves and the slider is formed with a pair of upper outer guide grooves and a pair of lower outer guide grooves correspondingly. The guide grooves are arranged such that two contact points between a rolling member and an associated upper pair of inner and outer guide grooves and two contact points between a rolling member and an associated lower pair of inner and outer guide grooves define a straight line. Preferably, the center of each of the rolling members also lies on the straight line.
