● Introduction
6211 high precision bearing is single row deep groove bearing. The bearing is characterized by high precision, high speed, low noise and long life. The steel balls conform to standard GB/T 308.1-2013, steel balls are made of GCr15. The great contact stress is generated between balls and rings when bearings are subjected to large local alternating loads during operation, so the bearing steel is required to have high hardness, wear resistance, sufficient fatigue strength, certain toughness and corrosion resistance, good dimensional stability, etc. The material of the bearings is GCr15, which is in accordance with ISO 683-17:2014, quenched (oil quenching) at 830~860°C and tempered at 150~180°C (2~4h). Bearings are widely used in instruments and meters, automobiles, internal combustion engines, motorcycles, agricultural machinery, automated office machinery and other fields.
● Production Details
Steel shear off the weight of the material section must be controlled in a certain range, under the material tolerance is about 2% to 3% of the weight of the material, the material diameter is small, take the large value. When the diameter of the material is less than 30mm, the material tolerance should be enlarged. The punching process for press forging rings involves punching away the core of the formed material, or cutting the inner and outer rings of the pylon billet, or punching a through hole in the center of the upset billet. This reduces the wall thickness of the blank while expanding its inner and outer diameter dimensions and changing the shape of the forging cross section. The upsetting of the material section is free upsetting. Due to the existence of section inclination and collapse angle of the material section, there is a big difference between the uniform deformation of the material section upsetting and the ideal member column upsetting. Since the collapsed angle is produced by the spherical deformation, the spherical deformation must produce strong hardening, so the hardness outside the collapsed angle increases and the deformation resistance increases.

● Precision Standards
The fit of bearing outer ring and housing hole is different from that of GB/T1801-1999 with the same name in the base shaft system although the code of dimensional tolerance is the same, but the nature of the fit is different.

● Bearing Inspection
Because the inner ring and outer ring of rolling bearing are thin-walled parts, in the manufacturing and storage process is very easy to deformation (such as become oval), but when the bearing inner ring and shaft or outer ring and shell hole assembly, if this deformation is not large, very easy to be corrected.
