precision bearings precision angular contact ball bearing According to the ISO classification standard, precision bearings are divided into: P0, P6, P5, P4, P2. The grades increase in turn, among which P0 is ordinary precision, and other grades are precision grades. Of course, different classification standards and different types of bearings have different classification methods, but the meaning is the same. In terms of the performance of precision bearings, the rotating body is required to have high runout accuracy, high-speed rotation, and small friction and friction changes.
