Cup Bearing
The cup bearing is an integral part of the tapered roller bearing assembly used in mud pumps. It serves as the outer race in which the cone (inner race) and rollers rotate, enabling smooth, controlled rotation of the shaft components under heavy radial and axial loads. Its precision-fit design supports high-speed rotation and contributes to the overall mechanical efficiency and longevity of the pump.
Cup bearings used in mud pumps like those from FMC BEAN, ATLAS COPCO (Trido series), and TRIAQUA must endure extreme drilling conditions, including vibration, heavy shock loads, and high-pressure operations. Manufactured from hardened alloy steel, these components are engineered to resist fatigue and wear, ensuring reliable performance even in abrasive environments.
All cup bearings in this category are OEM-compatible and built for high durability and easy installation, making them ideal for preventive maintenance or full rebuilds of industrial mud pumps
