Product History

The DriTran concept evolved when increased production needs of industrial equipment began resulting in ball screw drive failures. As ball bearing based devices were exposed to increasingly extreme environmental conditions and performance expectations, sudden catastrophic failures began to occur more frequently. To avoid down time of entire production lines, application engineers began removing the ball bearings from damaged drives, placing the screw inside the nut housing and filling the thread path with an off-the-shelf epoxy. Once cured, the configuration allowed a machine to perform production tasks at reduced speeds, while a replacement drive system was in transit. To improve on this simple idea, TranTek tested countless combinations of epoxy formulas, lubrication materials, thread configurations,
and production techniques. The results are an ideal industrial drive system incorporating a DriTran trade-secret-composite nut mated to a multi-start high-lead screw. With an efficiency of 80%, excellent wear characteristics and extraordinary strength, this configuration provides an extremely reliable drive method.
