Liner hanger bearings are mainly used in the field of petroleum cementing. The bearing adopts full complement conical convex roller bearings, and uses finite element analysis to optimize the structure and main parameters of the bearing body, reduce stress concentration, improve bearing capacity. The bearing uses special sealing device to prevent mud from entering the bearing, and fills high temperature grease to ensure high temperature lubrication.
The bearing can prevent the influence of uneven bearing load and overturning load, and it has higher axial load capacity and working ability in high temperature mud environment, lower rotating torque in harsh environment of high temperature and high load, and longer service life. It provides a guarantee for the reliability of the use of the rotary liner hanger.
