Why Use Linear Guides and Ball Screws with Ball Chains?
One of the differences between radial ball bearings and recirculating ball linear guides has historically been that radial bearings typically use a cage to separate the balls and control their movement, whereas profiled rail guides did not. But in the early 2000's, manufacturers of profiled rail
