Ball Cage Linear Guideway

``1. The BC series contains BALL CAGE in each block so that the steel balls will not touch and even clash with each other, and this application is suitable in high-speed linear motion. 2. In the BC series, contact angles between steel balls and retainer are smaller. Hence, by means of the sufficient use of lubricant, constant lubricity is utilized and eliminates frequent maintenance and oil pumping work. 3. Due to the BALL CAGE, which is made from macropolymer, the lubricant membrane exists among the retainer and steel balls, decreases friction coefficient and lowers the noise dramatically. This advantage is especially fitting and favorable to precision equipments, such as semi-conductor appliance, medical equipments, and optical instruments, which advocate strict requirement against noise. 4. Since the BALL CAGE keeps identical intervals between steel balls, the mass load is shared equally that the blocks life extends.``
