Pinion gears

Pinion gears for civil aviation: reliability under pressure

A three decade-long experience in producing sector gears for Boeing has inspired UMBRAGROUP to successfully apply its know-how to the making of pinion gears, to complete its offering. These gears work coupled with sectors and are traditionally made in steel that is first case-hardened and then cadmium plated. With the view to continuous improvement that distinguishes us, in 2005 we developed a dedicated technology to produce Cronidur-30 stainless steel pinion gears.

Stainless steel pinion gears: advantages

Stainless components enhance flight control systems’ performance and reduce maintenance interventions, guaranteeing:

  • Fewer chronic corrosion problems;
  • Exceptional wear resistance due to the hardening of the material.
