Designed for the powertrain and machine tool industries this large capacity roundness tester utilises a rotating gauge head mounted on a vertical straightness unit, the rotating head allows manufacturers to measure roundness of prismatic or non rotationally symmetric components such as engine blocks, crankshafts, cylinder heads and many more.

These systems are extremely popular in the measurement of lage diameter bearings and non-rotationally symmetric components. The system is based around Taylor Hobson's popular Talyrond 500H range and utilises a frictionless air bearing spindle and high accuracy column with adjustable positioning to allow measurement of bearings up to 1 meter in diameter.
