ABSTRACT:
A track system for roller-equipped carriers to run along a straight and/or curving guide rail, which includes two pairs of opposed parallel plain lanes, a pair of oppositely directed parallel V edges intermediate the two pairs of plain lanes, and narrow lubricating grooves along each V edge. Each carrier has a frame and roller assemblies, each having a pair of ball bearings mounted on a journal, spaced apart from each other and beveled oppositely on their adjacent outer race corners, so that the base areas of V edges engage between the beveled corners, and the top areas of V edges remain free within the space between the outer races in each pair, the outer races mostly rolling on the plain lanes. Each curving rail segment is provided with straight extensions formed on both ends to be connected to straight rail segments.
