Precision bearing

Precision bearing

Precision bearings are classified according to ISO grading standards: P0, P6, P5, P4, P2. The grades are increased sequentially, of which P0 is ordinary precision, and other grades are precision grades. Of course, different grading standards, different types of bearings, their grading methods are different, but the meaning is consistent. The performance of precision bearings requires that the rotating body has high runout precision, high speed rotation and small friction and friction changes.

Precision bearings and ordinary bearings should be distinguished from the following points:

1. The dimensional requirements are different. The product with high precision grade has different dimensional deviation (inner diameter, outer diameter, ellipse, etc.).

Products with low grades require a small value;
2. The required value of the rotation accuracy is different. The rotation accuracy (inner radial runout, outer radial runout, end face to raceway runout, etc.) of the product with high accuracy level is stricter than the value required by the product with low accuracy level;
3. The surface shape and surface quality are different. The surface shape and surface quality (surface roughness, circular deviation, groove deviation, etc. of the raceway or channel) are lower than the accuracy grade. The value required by the product is strict;
4. Products with particularly high precision grades are more advantageous than those of general precision grades.

In general, the accuracy grade of the rolling bearing finished product is divided into the following six grades (low to high): 0; 6; 6X; 5; 4; 2.

Delivery/Shipping:
1. FedEx, UPS, DHL, TNT ( The most fastest shipping methods for small packages, usually it takes 3-6 days for shipping );
2. China Post EMS ( Slow, usually it takes 15 working days for shipping );
3. By Air ( Usually more than 150-200kg and it takes about 5-7 woking days for shipping, fast but expensive);
4. By Sea ( Usually more than 100kg and it usually takes 25-30 working days for shipping, slow but cheap ).
