Frequently Asked Questions

Let's face it, Sometimes it happens, That's why we're here to make them Last Longer & Better!!

 

Ballscrews fail in machine tools due to one or more of these conditions…

  1. Normal wear, contamination, corrosion, brinelling, galling
  2. Poor maintenance (lack or excess of lubrication)
  3. Accidents resulting from electronic malfunctions
  4. Poor design-under capacity
  5. Overloaded or too high of a preload
  6. Bent O.D. of Shaft or Broken bearing journals
  7. Vibration or Misalignment (due to improper installation)
  8. Environmental
  9. Operator error
  10. Spalling / Flaking

Solution -

Ball & leadscrews are machined from top quality material, hardened and ground to super-precision tolerances. They usually do not need replacing when worn. As a result, it is economically feasible to service all types of ball screws by,

  • Regrinding O.D. of the screw

  • Regrinding I.D. or replacing ball/ballnuts

  • Resetting preload back to OEM specifications by replacing balls

  • Full torque testing
