Thomson Aerospace and Defense engineers, metallurgists, production specialists and customer service representatives provide the industry‘s most reliable repair and overhaul service. We evaluate the condition and performance characteristics of each ball screw shipped to us, including:

  • Straightness
  • Ball groove form
  • Wear
  • Metal fatigue
  • Chrome coverage
  • Bearing surfaces and attachment points

 

Once the initial inspection is complete, we provide a detailed assessment along with recommendations for repair or remanufacture. Depending on the condition, we will advise the most suitable method of repair in order to provide “like new” performance at the lowest cost. Using the latest technology, we will rebuild your assembly per the repair and overhaul manual specifications. The repair and overhaul process includes:

  • Eddy current inspection
  • Chrome strip and replate
  • Replacement of worn components
  • Efficiency testing
  • Backlash testing
  • Wiper torque testing
  • Lubricant retention

 

As a result, each ball screw assembly that leaves our repair and overhaul and repair facility meets the same stringent performance criteria as a new assembly. We are so confident in our service and quality control that each repaired assembly carries a three-year warranty covering any defects in material or workmanship.
