128709K 45*77*180mm high precision bi-directional angular contact bearing pack

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.

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.

Down hole motor or drilling motor for the oil drilling industry

Bearing Assembly of Downhole Motor is used to transmit motor rotary dynamic force to the bit, meanwhile to withstand axial and radial load from drilling weight. Inside of the Bearing Assembly,Monton uses TC Radial Bearing and a stacked thrust bearings. The thrust bearings support the downward force resulting from the “weight on bit” (WOB) and the loads from the combination of hydraulic thrust and weight loads from internal components.Monton provides different bearing assemblies, designed to meet the diverse requirements of the drilling industry.
