Discern between true and false high temperature resistant bearing

High temperature bearing discern between true and false methods: 1, high temperature resistant bearing identification, some normal parts with some mark on, than zhi assembly symbols, such as gear mark symbol at the top of the part to ensure that the correct device and not can't buy. 2, the high temperature resistant bearing color, some original parts surface to specify a certain color, if encounter other colors, it is fake and inferior parts. 3, the high temperature resistant bearing surface, the original factory accessories surface printing or hand type and symbols clear formal, rough but pretend to product appearance. 4, watching paint, unscrupulous businessmen will waste parts by a brief processing, such as the disassembly and assembly, to spell, gather together, paint and other processing, impersonating products sell, illegal access to high profits. 5, the high temperature resistant bearing quality, original accessories data according to the design requirements are qualified, posing as the product is to use the cheap substitute defect data. 6, see the gaps, the regular assembly components necessary to completely in good condition, to ensure smooth installation and normal operation. Some small parts assembly on a single packing, is generally 'gray', these difficult to device formation. Often because of a single small parts missing, form the whole assembly parts. 7, high temperature resistant bearing storage, auto parts if appear weather-shack, oxidation, discoloration or aging problems, may be in hosting a temporary environment, long storage time, data reason formed its own character. 8, the high temperature resistant bearing joint, if produce clutch plate rivet joint loose, brake hoses are degumming, electrical parts to take off the welding seams, paper filter off wait for a phenomenon, cannot use. 9, the high temperature resistant bearing packing, the original factory accessories packaging is compared commonly specification, unified standards, the printing handwriting clear formal, and pretend to be the product packaging and printing is poor, often can simply identify vulnerabilities in packaging. 10, the high temperature resistant bearing technology, the defect product appearance although on occasion, but due to poor workmanship, simple appear crack, sand holes, slag inclusion, burr or bruised. Cylinder pad kneading deformation, when using simple cause untight seal and ablation, lead to the oil, gas leakage and leakage phenomenon; Piston and piston ring surface has burr simple cylinder.
