Assembly and maintenance instruction ball bearing
spindle
Ball bearing spindle foot nuts without strippers)
The delivery of the ball bearing nut with assembly bushing (ready-for-assembly) as well as the
spindle are corrosion resistant. The ball screws are not mounted.
The ball screws are precision parts and need to be handled with cleanness and care.
The ball nut is packed ready for assembly.
Please take the ball bearing spindle off the packing only directly before assembly.
5.1
Assembly
Thoroughly clean the spindle up to the groove of the thread.
Remove the retaining ring on the side of the assembly bushing which is not displaced.
Push the nut with the assembly bushing over the treated shaft end (concentrically put on the
spindle axis, refer to the illustration) and push it carefully and completely onto the spindle.
Remove the assembly bushing only after having completed the assembly.
Adjust the clearing between the nut and the spindle with the adjusting screw (refer to the
illustration). It should be possible to move the spindle slightly into both directions. Check the
clearing at several points along the whole length of the spindle by holding the spindle and
moving the nut axially; there must be no clearance (the axial clearance will be atteined
before the radial clamping).
