摘要： A four-way linear ball sliding guide includes four rows of steel balls held in four troughs which are positioned diagonally with each other. Each trough is connected to an arched circulation path. Effective steel ball sliding guide hence has greater loading rating and stiffness. The steel balls can move smoothly in the trough and the circulation path.
