● Introduction

6220 ZZ bearing is single row deep groove bearing. The bearing is characterized by high precision, high speed, low noise and long life. Bearing clearance is an important technical parameter, such as if clearance is too small, it will cause heat heating problem, and even cause the bearing in operation "bite" phenomenon. Therefore, according to the type of bearings and working conditions to choose different levels of bearing clearance is very important. 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 agricultural machinery, household appliances, engineering machinery, automated office machinery, automobiles, internal combustion engines and other fields.

● Production Details

The quality of the raceway processing (such as surface roughness, size and geometric shape accuracy) will directly affect the performance and life of the bearing. If the surface roughness is poor, will increase the friction torque of the bearing, causing vibration and noise of the bearing. The shape of the raceway surface and raceway position error will affect the placement accuracy of the bearing. Therefore, raceway grinding is an important process to improve the quality of bearing products. Bearing steel annealing diffusion annealing, stress relief annealing and spheroid annealing and other types. The annealing of bearing ring forgings should be spheroidized. Spheroidizing annealing changes the organization into a uniformly distributed fine-grained pearlite, providing the most dwelling original organization for quenching, improves the solubility, reduces the hardness, and facilitates the cutting process later. According to the bearing ring blank forging metal temperature, forging is divided into executive forging, cold forging and warm forging three categories, the metal plus executive to the recrystallization temperature above the forging process called hot forging, metal deformation at room temperature called cold forging, and between the two metal deformation called warm forging. Now a large number of processing methods used or hot forging.
