Precision bearings distinguish

Edit: Rihoo Industry (Hongkong) Co.,Limited    Date: May 19, 2016

Bearings, precision bearings and plain from the following are distinguished:

1, size values are not the same, high precision product dimensions (inner diameter, outer diameter, ellipse, and so forth) than white

Precision bearings

Precision bearings (10)

Low grade of less value to product requirements;

2, running accuracy requirements are not the same, products with high precision rotation precision (radial runout, outer diameter to the beat, end face roller conveyer's jumping and so on) are lower than the accuracy value of strict requirements for products;

3, surface and surface quality of the requested value is not the same shape, high accuracy surface quality of product shape and its surface (roller or Raceway surface roughness, rounded shape deviation deviation, ditch, etc) are lower than the accuracy value of strict requirements for products;

4, high accuracy grade of the product and its materials than the average grades of the material properties of the products is desirable.

Under normal circumstances, rolling bearing accuracy of the finished product is divided into the following six levels (from low to high): 0;6;6X;5;4;2.
