Gear Units

Over 20,000 gear unit assemblies…with NO failures. ORX prides itself on having assembled new gear units for OEMs and overhauled gear units for a large number of transit authorities. Our gear units are fully tested — we have equipment for no-load spin testing and for load testing of completed units.

What’s more, ORX offers preliminary testing of separated and integrated drive units using sophisticated vibration analysis software that allows us to detect problems with gearing and bearings. This testing goes far beyond simply monitoring the gear unit's bearing temperatures. Internal problems show up clearly at unique frequencies determined by each part's geometry and the running speed of the unit.
