Our main railway wagon without axle box type double row circular cone roller bearings 2018 - structural type profile 09 - 13 with sliding bearing, the original railway wagon began in 1965 for the experiment of rolling bearing research, designed the 97826 and 97726 without axle box double row circular cone roller bearings. In 1973 began to study production 197726 type bearing. In the railway wagon to the beginning of the transformation of rolling bearings, sliding bearings to take a variety of models bearing loading operation test. Bearing types are divided into a short cylindrical axle box bearings, taper roller rolling bearing axle box, axle box short cylindrical roller bearing; Bearing model is divided into domestic 97720, 197720, 97726, 197726, 97730, 42726, 152726 et, et, 172726 t, 172726 yt, 172826 e, FAG NSK company of company of 197726 a, 197726 b, 172826 a, NTN NSK company the company's 197726 c, etc. By running the test, no axle box type 197726 double row circular cone roller bearings with railway wagon batch, this is our country railway freight of rolling bearing is an important turning point, from the rolling bearing in railway truck loading using a lot.
