Ball Screws Overhauled, Manufactured and Distributed by Skytronics

For more than 40 years, Skytronics has provided aftermarket support for Boeing horizontal stabilizer ball screw assemblies to a broad spectrum of aircraft. Since 1985, Skytronics has been manufacturing these assemblies in support of the commercial aircraft aftermarket, having gained manufacturing approval from Boeing and the Federal Aviation Administration (FAA).

All ball screw parts and assemblies meet Skytronics' rigid quality control standards and are approved by both Boeing and the FAA. In addition, all ball screws are placed onto an assembly before shipment, guaranteeing both fit and function, as well as 100% dimensionally inspected using original prints, test fixtures and tooling. Best of all, we ensure the lowest price, fastest delivery and highest quality.
