Universal Shaft Assembly

Our range of Universal Shaft Assembly is the main component of the Downhole Motor. The function of cardan shaft is to convert planetary motion into fixed constant rotation of drive shaft, to transmit torque and speed from motor on the drive shaft, and to the bit. Cardan shaft mostly use flat shaft. But some are flexible shafts. Our flat type shaft used on our downhole motor is made by linear cutting technology, it has longer running life and less mechanical loss.
Downhole motor shall be disassemblied as quickly as possible after use to examine cardan shaft, if it is found out that wear degree is over maintenance standard, relevant consumable components shall be changed promptly. If it is not, downhole motor can not be running normally due to over run time of cardan shaft.
