Inspection And Repair Of Single Nut Pair

For single nut ball screws, the clearance between the screw and nut pairs cannot be adjusted. If it is detected that there is a gap in the screw nut pair. First, check whether the thread arc of the lead screw and nut has been worn. If the wear is serious, the complete set of lead screw and nut must be replaced.

If the inspection is slightly worn, it can be repaired by replacing the ball with a larger diameter. First, detect the maximum clearance of the screw nut pair, convert it into an increase in the diameter of the ball, and then select the appropriate ball to reassemble. Such maintenance is more complicated, takes a long time, and requires a high level of technology.
