Mud stack thrust bearings 
Mud bearings close to the drill string end have a major impact on productivity and reliability. In addition to severe axial and shock loads, these bearings are "lubricated" with highly abrasive mud, which for a bearing is the definition of an extreme operating condition. Monton's mudstack bearings are optimized for our customers' applications through rigorous finite element analysis and physical lab tests by testing the bearings with drilling mud circulating through them. 
Monton mudstack bearings provide:
• Improved wear resistance 
• Increased load-carrying capacity
• Optimized load distribution
• Increased robustness 
• Improved reliability 
• Customized design
