NB’s regular slide bushes. But between the ball retainer and the outer casing, there are rotational ball circuits as well that allow the entire retainer and shaft to rotate within the stroke bush unit. This is just one example of the various types of bearings that can combine rotational and linear motion. Allowing for this motion though often requires a larger unit than other bearings relative to the size of the shaft. (read more)
