精密轴承与普通轴承的区分:
Distinction between precision bearing and common bearing:
1、尺寸要求值不一样,精度等级高的产品其尺寸偏差(内径、外径、椭圆等)都比精度等级低的产品要求的值要小;
1. The size requirements are different. The size deviation (inner diameter, outer diameter, ellipse, etc.) of products with high accuracy level is smaller than that of products with low accuracy level;
2、旋转精度的要求值不一样,精度等级高的产品其旋转精度(内径向跳动、外径向跳动、端面对滚道的跳动等)都比精度等级低的产品要求的值要严;
2. The required value of rotation accuracy is different. The rotation accuracy of products with high accuracy level (i.e. internal diameter run out, external diameter run out, end-to-end run out, etc.) is stricter than that of products with low accuracy level;
3、表面形状和表面质量的要求值不一样,精度等级高的产品其表面形状和表面质量(滚道或沟道的表面粗糙度、圆形偏差、沟形偏差等)都比精度等级低的产品要求的值要严;
3. The required values of surface shape and surface quality are different. The surface shape and surface quality (surface roughness, circular deviation and groove deviation of raceway or raceway) of products with high precision level are stricter than those of products with low precision level;
4、精度等级特别高的产品其材料要比一般精度等级的产品的材料性能更为有利。
4. The material properties of products with high precision are better than those of products with general precision.
