Mud pump bearings are a type of bearing specifically designed for use in mud pump equipment and are capable of withstanding radial and axial loads and media impacts generated during high-pressure transportation. When operating, the mud pump converts mechanical energy into hydraulic energy through the reciprocating motion of the crankshaft, piston, or plunger, allowing mud containing solid particles such as sand and gravel to flow at high speed under high pressure. This mode of operation requires the bearings to withstand continuous alternating loads, erosion and wear from solid particles in the mud, and potential corrosion from the media. Furthermore, they must adapt to vibrations and certain temperature increases during equipment operation. Therefore, mud pump bearings are specifically designed in terms of structural strength, material wear resistance, and sealing performance. Their core characteristics are excellent wear resistance, impact resistance, and sealing reliability, enabling long-term stable operation under high-pressure transportation conditions of media containing impurities.
