As of powder metallurgy technology matures, China''s oil bearing has a lot of use of powder metallurgy technology, which the oil bearing must be stored in non-absorbent containers, because its precision is very high,the daily storage process should also be good pollution prevention work. Made by powder metallurgy oil bearing its precision is very high in production after the completion of the supplier and the purchaser should develop some protocols can not be used before oil immersion chlorinating agent to degreasing or cleaning the bearing surface stains. Because the residual solvent tend to form weak acid, it is possible to make the bearing wear.
Oil bearing due to some uncertainty factors in the production process may result in the bearing surface is very rough to deal with the roughness of the surface using a technique called a time the tapered control pin measuring instrument measurements undetectable real rough degrees, it shows the surface of the interconnected porosity than the metal surface of uneven depth. Encounter this situation, can not ignore the impact of the oil bearing surface roughness produce finished it, this time should be to stop production, careful analysis of failures in what? Find out why.
