The protector is set between separator or intake and motor in ESP unit. Except for the connection function, the following is the main feature;
1. Seal the power output of the motor to prevent well fluid from entering into the motor;
2. Balance the pressure between the tube annular room and the inside of motor.
3. Balance the axial force of the shaft and separator shaft.
4. Meet the need of expanding and contracting in motor.

No.1 Needle Roller Bearing Description:
Needle roller bearing of Linqing City GaoYuan Bearing Co.,Ltd is a bearing which uses small cylindrical rollers.
They are used to reduce friction of a rotating surface.
Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of the shaft and the diameter of the bearing) so they are much more compact.
The typical structure consists of a needle cage which orients and contains the needle rollers, the needle rollers themselves, and an outer race (sometimes the housing itself).
Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.
Full complement bearings have solid inner and outer rings and rib-guided cylindrical rollers. Since these bearings have the largest possible number of rolling elements, they have extremely high radial load carrying capacity and are suitable for particularly compact designs.
