Symmetric design of key components with high rigidity gives the high precision measuring capabilities for the very large and heavy gears. Newly developed measuring system “NDG” reduced the tangential motion drastically. This method gives the accurate and consistent results as all measurements are done at the center of bed. This tester measures large gears and still saves much floor space with its compact body. It also has automatic alignment system, which macks it easier and faster to align the pose of large gears. This function contributed to shortening of measuring time including the gear alignment. Please feel free to contact us for large gears with outer diameters exceeding φ2000 mm.
