● Introduction

6221 bearing is single row deep groove bearings. It is produced by our company in accordance with the national standard GB/T 276-2013. The company is equipped with advanced processing and testing equipment, equipped with professional testing department and has a perfect quality control system to ensure the material, dimensional tolerance, clearance, noise and vibration of the bearings meet the standards. Deep groove ball bearings are mainly used to bear radial load, but also commonly used to bear radial and axial combined load. Especially when the speed of mechanical equipment is very high, it is not suitable to use thrust bearing, the bearing can be used to bear double directions axial load. The precision level of bearings is in accordance with the standard GB/T 307.3-2017. The precision level of bearing is P0, P6, P5, P4 and P2. The rolling bearings are precision mechanical products, the tolerance level of P2 is relative to the standard tolerance of IT2, the tolerance level of P0 is relative to the standard tolerance of IT7~IT8. Bearings are widely used in home appliances, instruments, instruments and meters, roller skates, construction machinery and other fields.

● Production Details

1. Bearing steel annealing process, general GCr15 bearing steel blank forgings annealed hardness 88 ~ 94HRB, microstructure 2 ~ 4 levels, decarburization layer depth 0.2 ~ 0.3mm, annealed quality most can reach IB/T1255-2001 high-carbon chromium bearing steel rolling bearing parts executive processing technical conditions requirements. The bearing ring must be ground after the executive treatment, so that the working surface can get the required technical specifications. Grinding is one of the key processes in bearing production, and the main task of grinding is to complete the grinding process with high precision, high efficiency and low cost.

2. Tube material: mainly used in the large-volume production of small and medium-sized penal bearing integrated automatic line, directly with a single-axis or multi-axis automatic lathe turning, small turning volume, high production efficiency. The size of the tube material is generally 20~80mm, not more than 105mm, the small diameter of the collar choose cold steel pipe, the diameter of the large can choose hot-rolled steel pipe. Bearings made of steel pipe life than ordinary forgings made of bearings to high. The disadvantage is that the price of steel pipe is more expensive and insufficient specifications.
