Brief introduction of retaining ring in powder metallurgy

Powder metallurgy middle retaining ring refers to a series of middle retaining ring produced by powder metallurgy process to replace steel middle retaining ring. Its material organization u003d pearlite + graphite + cementite + pores.
The high-hard particles are distributed on the softer matrix, and together with the solid lubricant in the matrix and the lubricating oil in the pores form a special friction-reducing and wear-resistant material, and its wear-resistant life is increased by more than 9 times. Generally, the outer diameter is less than 200mm and the wall thickness is more than 2mm.
