23176CA/W33 Mud Pump Bearings, Brass Cage
The 23176CA/W33 Mud pump bearings are suitable for high-load, high-impact applications such as oil and gas drilling, mining and metallurgy, geological exploration, and dredging projects. Classic applications include mainstream mud pumps such as NOV, Emsco F series, Gardner Denver, and BOMCO, as well as key support components in horizontal directional drilling rigs and slurry transfer pumps.
The 23176CA/W33 bearing is a Spherical roller bearings, double row with an inner diameter of 360 mm , an outer diameter of 620 mm, a width of 194 mm. High-carbon chromium steel rings, High-carbon chromium steel rolling mlement. Its dynamic radial rated load is approximately 4560784 N, its static radial rated load is approximately 7099873 N. It uses Normal standard radial clearance, open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
23176CA/W33 bearings ( 360 mm x 620 mm x 194 mm) have the advantages of High load, strong impact, and are therefore widely used in the Drilling pumps for oil and gas drilling.

Mud pump bearings are designed for extreme operating conditions. Key advantages include extremely high combined load capacity to withstand high impact and pulsating loads, as well as excellent contamination resistance and self-sealing performance. Multi-layer labyrinth seals and corrosion-resistant materials effectively prevent the intrusion of abrasive mud. They also possess excellent self-aligning capabilities and high-temperature resistance, ensuring high reliability in harsh environments with heavy pollution and continuous operation.
