Impact of bearing storage for too long: the characteristics of the lubricating grease in the bearing may be affected after long-term storage of the bearing with sealing ring or dust cover.Scientific storage of imported bearings is very important. If ......
Imported bearings can be used for 2-5 years, while domestic bearings are generally more than 2-4 years. At present, the main shaft bearings are mostly unnatural damage, and most of them are premature damage caused by bearing the intrusion of foreign ......
P4 bearing has higher dimensional precision and rotation precision than P5 bearing.The grades of bearings are divided into four levels: po-p6-p5-p4-p2. Po level is the national standard and the most common standard in the bearing industry, so it is a......
The numbers on the bearing indicate the bearing model, bearing type, size, etc.Example:30206:3 represents tapered roller bearing, 0 represents width series 0, 2 represents diameter series 2, and 06 represents bearing inner diameter of 30mm.6203:6 rep......
Both are tapered roller bearings with the same inner diameter, outer diameter and width. The latter B is the "post code" of the bearing, indicating that the internal structure of this bearing is different from that of ordinary bearings. Spe......
If you want to find a good foundry, you can directly go to Baidu or other websites to inquire. Then find out the manufacturers who can visit and cooperate. If there is no location requirement, you can take a look at Hefei Quansheng machinery. Hefei Q......
One method of calculating the friction torque of rolling bearings is to divide the friction torque into independent parts, including the torque M0 which is not affected by the load and the torque M1 which depends on the load, and then add the two tog......
(1) The application scope of GCr15 steel has been expanded. Generally, the effective wall thickness of the ferrule when GCr15 steel m is quenched is less than 12mm, but due to the strong cooling capacity of nitrate salt during BL quenching, if measur......
