Powertrain & Gear Testing

The GTR line - general purpose gear and powertrain test rigs

Overview

The GTR series is a highly adaptable and powerful gear train testing platform that enables testing of all commonly used types of gear pairs and complete multi-stage gear transmissions and actuators. The range of currently available torques, running speeds and sample temperatures is suitable for testing the vast majority of polymer and composite gear pairs and gear trains, as well as lower-to-intermediate power metal gearings.
