IG-IGA Series Roller Gear Indexers are developed combining roller gear cam input shaft and turret of output shaft, which are placed at right angles. In this industrial machine, preloading of two cam followers in taper rib is done to receive backlash even for holding load. These machines are best characterized for their little friction loss, minimal motor loss and great resistance from abrasion, all of which are the result of the fact that loads are received by rolling contact. In comparison to other similar machines, our IG-IGA Series Roller Gear Indexers are appreciated for their stability, reliability, ease of use and great speed.
