How do Thrust Bearings Work?
In down-hole drilling tools, large thrust loads can result from drilling and from the hydraulic loading caused by drilling mud flowing through tool components. This results in a large axial load that must be carried when mud is circulating through the tool in the off-bottom position. When the tool is drilling (on-bottom), the weight-on-bit (WOB) is transmitted to the motor drive shaft in a direction opposite to the loads resulting from the circulation of the drilling mud through the power section. Both the on-bottom and the off-bottom loads in mud motors (and other drilling tools) are taken up by thrust bearings. Why are diamond thrust bearings better than ball bearings? Conventional thrust bearing designs for down-hole drilling tools often utilize mud-lubricated or sealed ball bearings. US Synthetic PDC bearings provide a high-performance alternative to these conventional bearings. The diamond inserts in our thrust bearings are virtually impervious to abrasive particles in the drillin
