Drive shaft is to transmit motor rotary dynamic force onto the bit, meanwhile to withstand axial and radial load from drilling weight. We have the following two types of drive shafts:
1) Bit nozzle pressure loss is 7.0Mpa, Using hard alloy radial bearing and Drive Shaft Assembly with thrust bearings.
2)Bit nozzle pressure loss is 14.0 Mps, using hard alloy radial bearing and PDC cutter flat thrust bearing. It has longer lasting life and higher bearing capacity.
