INTRODUCTION OF BEARINGS STACKS
Our main bearings products including bearings of petroleum screw drilling tools,equal-wall-thickness rubber stator of petroleum screw drilling tools,roller bearings(bearing roll),55SiMoVa or 8620 steel ball of three-roller rock bit,roller,thrust block and pad as well as hobbing cutter shaft of coal mine development,and main and supporting components and parts of construction machinery.The bearings for petroleum screw drilling tools(multi-row thrust ball bearings)are our leading products developed and filled the gap of China in 1980s.Up to now,there are more than 20 series including over 200 models.
Downhole drilling motor bearings
Whether you’re drilling for oil or gas, the bearings in a mud motor at the end of a drill string have a direct impact on productivity and reliability.These mud motor bearings have to endure extreme operating conditions. 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.
How the new bearing works ?
The typical mud motor bearing contains between 8 and 12 rows for design optimization. When the bearing is new, the majority of the load is accommodated by the first four or five rows. As each row starts to wear, the load is shifted to the next row and the next until all the rows are worn equally. Then, the load is shifted back to the first row and the process is repeated. This unique Monton design enables the bearing to last significantly longer than previous bearing designs.
About the redesign process
To significantly improve bearing performance and reliability,Monton engineers used proprietary Monton design and simulation tools to
• accurately define the behaviour of a bearing stack
• redesign the bearing to minimize stresses and optimise load carrying capacity
• test new designs and materials. With the Monton virtual test rig, engineers were able to identify and correct the problem of cracked rings and sheared balls – two common problems with these bearing
• Special steel for all bearing components
• Full complement bearing
• Precision matched rings
• Unique bearing design to support heavy axial drilling loads
• Improved wear-resistance
• Increased load carrying capacity
• Optimized load distribution
• Increased robustness
• Improved reliability
• Customized design
