Linear motion guide unit having a synchronized retainer

摘要

A linear motion guide unit includes a pair of guide members each formed with a guide groove and provided to be relatively movable parallel with a longitudinal axis of the unit. A plurality of rolling members are provided in rolling contact with the guide grooves of the guide members. A retainer assembly, including a retainer plate formed with a plurality of windows and at least one grooved wheel mounted at one end of the retainer plate, is disposed in a space defined between the guide grooves. A wire is passed around the grooved wheel and fixedly attached to the guide members. The total length of the retainer assembly is shorter than either of the guide members.
