    Alignment of bores and other circular machine elements.

    CENTRALIGN Ultra is a laser alignment system designed for the measurement and alignment of bores and internal elements of rotating machines such as bearing rings, diaphragms, nozzles, inner shells and turbine casings with upper halves installed or off. It offers a far more convenient and accurate alternative to the traditional methods using piano wires, micrometers and cumbersome theodolite telescopes.
