Mud motor bearing

Mud motor bearing are special bearings that transmit downhole power and torque and bear axial forces in oil screw drilling. This type of bearing is mainly composed of multiple rows of thrust balls and is mainly used for downhole power drilling tools and maintenance. In terms of design and production, the outer diameter of Mud motor bearing can be designed and produced according to user requirements, generally size from Φ50 to Φ290mm. In order to improve the wear resistance, service life, corrosion resistance, impact resistance and load bearing capacity of the bearings, the bearings will use a carbide layer, a supersonic thermal spray layer, and an internal thread and keyway for easy installation and positioning. The material of oil screw drill bearings is usually 55SiMoVa or 8620 carburizing steel, which has high hardness and wear resistance and impact resistance, and can meet the working requirements of complex downhole environments.

Mud motor bearing are often made of 55SiMoVa or 8620 carburized steel, and the bearing design service life around 300 hours. It is mainly used in the motor part of the oil drilling screw motor. Mud motor bearing are one of the important components of oil drilling rigs, used to support the drill pipe and provide axial load support. It can effectively reduce the impact of friction during drilling, improve drilling efficiency and extend the life of the drill bit. Mud motor bearing can withstand huge axial loads also have good wear resistance and fatigue resistance. Mud motor bearing is composed of multiple sets of ball bearings and can withstand greater axial loads. When rotating, the mud motor bearing is generally equipped with oil lubrication to make the operation smoother. Mud motor bearing can withstand greater axial loads, and can also withstand a small part of the reciprocating load and radial load. Mud motor bearing are assembled by professional thrust bearing assembly machines, and the manufacturing precision of each part is very high, making it more stable under low speed and high pressure. Mud motor bearing for drilling rigs are widely used in the field of oil machinery, providing customers with convenient installation and low-cost maintenance.
