1、Adjustable Bend Housing
In the special processes of directional well, horizontal well and extended reach well, the adjustable angle drilling tools adopt the new type cardan shaft housing design, able to meet 19 different angle adjustment ranging 0-4°

2、New type oil sealed
Changing the common mud- lubricated drive shaft to oil-lubricated drive shaft, improves the working environment of the thrust bearings and radial bearings, increasing the life time of the complete downhole motor.

3、Connecting Rod Assembly(Ball)
Ball drive universal shaft adopts the ball, rod and hinge link to transmit the torque, using high temperature grease to lubricate friction,sealing the steel ball motion parts with rubber sleeves, isolating sharpening drilling fluid. The working surface of ball drive universal shaft is processed with special surface treatment, for a relative increase of its surface hardness and high temperature resistance,hence the wear resistance and the reliability can be further improved and the service life is prolonged correspondingly.

4、 High temperature resistant motor。
The stator rubber of high temperature resistant motor is synthesized by a special technology, assuring the motor can work
normally under 150 C high temperature. It is suitable for the drilling operation of high temperature well and ultra deep well.

5、 Rotor surface treatment
Special chromium coating technics can control the thickness ratio of chrome coating apex and trough to 1: 2 Tungsten carbide spray coated rotor can make the rotor work normally under the working condition of saturated saltwater mud, successfully solving the corrosion problem of the chrome plated rotor by the saturated brine.

6、Replaceable stab|zer
In order to meet the need of drilling the housing of the downholemotor drive shaft as sembly is equipped with different kinds of stabilizers, with the fixed type and the replaceable type. The stabilizing forms of the stabilizer are various and the customers can make selection according to the requirement of the drilling technology.
