How to lengthen the life of your actuator

Because roller screws have numerous contact points versus ball screws, the life of the actuators lengthen substantially. However, many things will affect the length of life for a roller screw. Here are some tips to increase roller screw life:

  • Eliminate/mitigate side load/misalignment
  • Reduce (or ideally, eliminate) hard impacts/shock loads
  • No end crashing or hard stops. Bumpers are there for accidents only (use nice and controlled deceleration)
  • Switch up the portion of the screw being used for press applications (evenly distribute the wear)
  • Make sure wear parts are replaced as necessary (Front seal bushings and other seals/o-rings etc)
