Roller Cone Bits
There are rich and diverse roller bits to meet different requirements of formations and rotary speeds. The sizes of the gage diameter and the types of bit are strictly designed in accordance with the standards API Spec.7.
There are rubber sealed bearing bits and metal face sealed bearing bits, and all bits are lubricated by new type of wear resistant grease that can sustain high temperature up to 250°C.
The surfaces of main or key parts are hardfaced and treated with friction reducing technology. They can enhance gage protection and prolong the life of bit.
