The Vector™ Series 55RS drilling motor is designed specifically for RSS motor assist applications. The driveline incorporates a bearing mandrel made of high-strength alloy steel that is designed to withstand extreme bending stresses and provide exceptional torque handling capability. The extended mud lubricated thrust stack supports the mandrel over its length and enables the bearing assembly in handling high axial loads. The assembly also features upper and extended lower radial bearing sections significantly enhancing the motor’s capacity to absorb and manage sideloading when compared to conventional designs.
Coupled with the hybrid flex shaft, which facilitates torque transfer to the bearing mandrel via. flat faces at the pivot joint on one end and with the other end connected directly to the rotor - the Series 55RS drilling motor provides superior torsional load capability and increased motor reliability. The ability to run in high temperature and varied mud system applications makes this tool robust and compatible for extended drilling hours. With a robust mandrel catch system that greatly minimizes the possibility of LIH scenario, the Series 55RS bearing pack technology encompasses all the features needed making it an ideal choice for RSS assist motor applications.
