Bearing

Cylindrical Roller Bearing
Cylindrical roller bearings can be divided into single row, double row and multi row roller bearings. All of them are separated bearings, which are convenient to install and disassemble. The contact type of inner, outer rings and roller is modified linear contact, so the friction coefficient is small and the limiting speed is high. Having the advantages of compact structure, high rigidity, large bearing capacity and smooth operation, Rundong cylindrical roller bearing is suitable for all types of mud pump, winch, reduction gear, and oil pumping unit and other oil drilling equipment.

F-1600 Mud Pump Bearing
Mud pump bearing includes cylindrical roller bearing and spherical roller bearing.
