What are the differences between tapered roller bearings U and V?
In the domestic new model, I look like this:/U - represents dimensional accuracy equal to P4V - means to fill a scroll (without a cage)/V - indicates that the maximum speed range of bearing vibration speed class and vibration speed level meet the standard V1 group, V2 group and V3 group respectively.If you take a closer look at the subject, you can't let it go.
At the end of the rolling bearing type may have the letter "U" or "V" and other letters, they are complementary code bearing types, said change technical conditions of bearing material and structure design, according to the provisions of the marked code.U - indicates that the clearance of the bearing is different from the current standard.V - rings and rolls are made of materials not often used in plastics.
You should be referring to imported tapered roller bearingsU: figures in the rear indicate tolerances for the total width of the narrowed bearingsV: optimize internal structure upgrades
