Tungsten Carbide Thrust Bearings Introduction

Tungsten carbide thrust bearing alloy overcomes the deficiencies of the prior art, which can effectively solve the problem of frequent replacement of the plain bearing in the mud under downhole conditions cuttings member, work intensity, low efficiency of the work. Thrust bearing aspect of carbide is achieved by the following measures: a thrust bearing comprising carbide inner, outer, abrasion and wear of the block; the left outside of the inner ring has an annular the boss, the boss on the right side of the inner package can be relatively rotatable with the outer; the boss right, left outer respectively inner and outer cladding by welding wear-resistant layer is attached to the fixed block interval, wear block height above the weld cladding layer; through the inside of the inner weld cladding layer spacing fixed mounted wear strips; formed through the flow channel between wearable pieces, wear strips and weld cladding layer.
