XMK Non-sealed Roller Air Bearing Mining Roller Cone Bits
The XMK series bits are non-sealed roller bearing bits that are cooled and cleaned by air with fast drilling speed and good strength which are used for the development of open-pit coal mines,iron mines,and non-ferrous metal mines
The thrust bearing is made of materials with high wear resistance,high hardness,and high tem-perature resistance to improve its load-bearing capacity.
The air-cooling system can improve the air circulation conditions in the bearing cavity and reduce the temperature inside the bearing cavity.
The cutting structure adopts circular arc hard alloy ball teeth to improve compressive strength and wear resistance and reduce tooth breakage rate.
The palm back is equipped with hard alloy teeth and welded with wear-resistant alloy to reduce wear on the palm back and extend bearing life.
