Of course, screw drives are subject to wear when they are dynamically stressed.

In order to minimize wear in an application, many basic considerations are first necessary:

  • How much wear and tear occurs?
  • How much wear is actually permissible in the application?
  • In which component (spindle or nut) will wear arise or become problematic?

Once these questions have been clarified, optimizations can be aimed for:

  • Increase in the area bearing share (e.g. longer nut)
  • Protection of the thread against external influences (e.g. wipers or bellows)
  • Improvement of the lubrication (e.g. different lubricant or different maintenance intervals)
  • Optimization of the sliding partners (e.g. change of materials)
  • Change of thread geometry (e.g. trapezoidal thread instead of metric thread)
  • Improvement of the surface (e.g. sliding coating or heat treatment of the spindle)

Junaspin is happy to help with the design. Thousands of test results are documented in our database. In addition to the pure calculation, experience from “real applications” and tests can also be incorporated.
