Product introduction: structure characteristics:

 

1.Using floating bearing structure, the floating element made of new materials with high strength, high elasticity, high temperature resistance, high wear resistance characteristics and surface bear solid lubricants treatment. While lower side relative linear velocity bearing, reduce the friction surface temperature rise, thus can effectively improve the high pressure or high speed drill bearing life and reliability of bearing hole conditions.

2.It uses precision metal seal. Metal sealing ring is the bearing axial dynamic seal, Tricone bit using the basic conditions which consists of a pair of elaborate design and processing of metal. Two high elastic rubber ring are respectively located in the energy supply tusks and cone sealing area as a static seal, seal compression ensures that the two metal ring sealing surface always maintain good contact optimization.
