The measuring gears are designed individually and translate into fast or slow depending on the requirements of the application. KBK manufactures the gear units in the VGA and VGB series: While the VGA gear units enable a rotary encoder to be attached directly via a pinion, the VGB version is connected to the gear unit via an assembly bell and a coupling.

Both series of measuring gears are available in five standard sizes with outside diameters of 65, 90, 120, 150 and 180 mm.
