China imported bearings and bearing how to distinguish

Bearing with everyone from bearing material, production technology, service life, bearing type, etc. , analysis how to quickly accurately distinguish imported bearing or domestic bearing is a bearing? 1, bearing material and process compared with domestic bearing, the general material is better than the domestic import bearing, heat treatment process is advanced, high precision manufacturing, manufacturing and assembly process more reasonable service life is long, and of course the price also will be higher. 2, bearing service life for life, although the imported bearing's service life is longer than domestic, but if the ordinary machine under the condition of the precision required degree is not high domestic can completely. Now some big domestic manufacturers of bearing quality is very good, the price is appropriate, but at the time of required precision may be imported bearing performance is more outstanding. Bearings specializing in the production of high precision stainless steel bearing, the need to control the cost of high precision bearing demanders can give priority to the bearing. 3, bearing type with the advent of the internationalization tide, the difference between the domestic bearing code with imported bearing code world gradually, the latest issue of the national standard, according to the domestic code consistent with the international ISO standard. This method can distinguish between a small part of the code have no consistent bearing. 4, bearing the brand code on the bearing as well as digital code said on the identity of the bearing type and some letters, these are generally brand code, often contact bearing users should have a look at will understand. After years of unremitting efforts, the domestic bearing production technology has been very mature, some large manufacturers can also be customized according to customer demand for bearings, relatively more cost-effective compared with imported bearing, is a very good choice.
