精密轴承按照ISO的分级标准分为：P0,P6,P5,P4,P2.等级依

Precision bearings in accordance with ISO standard classification is divided into:. P0, P6, P5, P4, P2 level progressively increased, which is normal precision P0, other grades are precision level. Of course, different grading standards, different types of bearings, their grading methods are different, but the meaning is the same. Precision rotary bearings having a high performance requirements on the runout accuracy, high-speed rotation and a change in friction and a small friction.

Precision bearings are divided into: P0, P6, P5, P4, P2. grade in turn, where P0 is ordinary precision, the other grades are precision levels. Of course, different grading standards, different types of bearings, their grading methods are different, but the meaning is the same. Precision bearing performance requires the rotating body with high beat accuracy, high-speed rotation and requires friction and friction change is small.

Precision bearings are divided into: P0, P6, P5, P4, P2 according to the ISO classification standard. The grades are increased successively, in which P0 is the common precision, and other grades are precision grades. Of course, different classification standards, different types of bearings, their classification methods are different, but the meaning is the same. On the performance of precision bearing, it is required that the rotating body has high runout accuracy, high-speed rotation and small friction and friction change.<br>
