Abstract
An improved stationary roller shaft of a gear assembly for an air turbine starter is provided. The air turbine starter may be used to start a gas turbine engine, such as may be found in aircraft, ships and military vehicles. The stationary roller shaft is formed of a material having a hardness of at least 66 Rockwell C and having a low inclusion content rating, thereby providing improved wear and/or fatigue properties.
