1. Bearing type notation: code name (the fourth digit from the right) 0: deep groove ball bearing 1: aligning ball bearing 2: cylindrical roller bearing 3: aligning roller bearing 4: needle roller bearing 5: spiral roller bearing 6: angular contact ball bearing 7: tapered roller bearing 8: thrust ball bearing Thrust angular contact ball bearing 9: thrust cylindrical roller bearing thrust aligning roller bearing thrust needle roller bearing thrust tapered roller bearing 2. Bearing size representation Diameter series, code name (third digit from right) Ultra light: 7 cases: 1000700 Ultra light: 8, 9 cases: 7000800, 7000900 Extra light: 17 cases: 7000100 7002700 Light: 2 cases: 3056200 Medium: 3 cases: 300 Weight: 4 cases: 2086400 Width series, code name (seventh digit from right) Narrow: 7 cases: 7000800 Normal: 1 case: 1000700 Width: 2 cases: 2007900 Extra width: 3 cases: 3000700 Example: 4774900 Height series, code name (seventh digit from right) Extra low: 7 cases: 7589900 Low: 9 cases: 9008900 Normal: 1 example: 1008900 3, bearing inner diameter representation Bearing standard inner diameter: 10 01 Inner diameter: 12 02 Inner diameter: 15 03 Inner diameter: 17 Code 04-99 Code number *5= ID Example: 205: ID 25, 206, ID 30 Bearing code is pronounced as: Front code: bearing clearance, bearing tolerance class Right digit of code number: 7: Width series 6. 5: bearing structure form Type 4: 3: Diameter series 2,1: bearing inner diameter Example: 3G3053220, that is, radial clearance according to the third group, G tolerance level, tolerance level according to the letter B, C, D, E, G, in order to represent the tolerance level from high to low. Class G is generally omitted from bearing codes 6305,6 for thrust angular contact ball bearings, 3 for medium series, 05 for inner diameter, 5 times 5 for inner diameter of 25

According to your description, it should be tapered roller bearing with outer diameter of 80, height of 25, inner diameter of 40 and height of 32. The bearing type is 33208

1.the difference between models With the advent of the international tide, the domestic bearing code is gradually in line with the imported bearing code. The latest published national standards show that the domestic bearing code is basically consistent with the international ISO standard. Bearing signs, such as domestic bearings famous is generally Luoyang shaft code is (LUO) and Harbin bearing code is (HA) is basically this, each bearing out a number code indicates that the bearing model outside the pinyin logo on behalf of the origin, if you are the mechanical industry should know. 2. Other aspects Compared with domestic bearings, imported bearings are generally better than domestic bearings, with advanced heat treatment process, high manufacturing accuracy, more reasonable manufacturing and assembly process, and long service life, of course, the price is higher. And imported bearings are generally authentic, the most important is...... The imported bearings are all made in foreign countries. Ha ha, you can understand that without saying. For the life, although the service life of imported bearings is longer than that of domestic bearings, if the ordinary machine is not very high in the case of precision requirements, the domestic can completely. Now domestic such as HRB,ZWZ and other large manufacturers of bearing quality are very good. The price is right, and it's affordable. But in the requirements of precision or imported point.
