● Introduction

6219 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. The precision grade of bearings conforms to the standard GB/T 307.3-2017. The precision grade of bearing is P0,P6,P5,P4 and P2. The P0 grade bearings can meet most of the applications, the P5 grade bearings are generally precision bearings, the P4 grade bearings are high precision bearings. The P2 grade bearings are ultra-precision bearings, such as those used in machine tool spindles, disk drive spindles, precision instruments, etc. The noise of the bearing conforms to the national standard JB/T 7047-2006. The noise level of the bearings is divided into Z,Z1,Z2,Z3 and Z4. The sources of bearing noise are vibration of bearing structure, vibration caused by ripple degree of parts surface, vibration of cage and vibration caused by dust. Bearings are widely used in low-noise motors, industrial pumps, household appliances, home appliances, motorcycles, transportation vehicles and other fields.

● Production Details

Bearing steel annealing process, the cooling speed is large, carbide fine, diffuse, general hardness is high: cooling speed is small, carbide particles are coarse, hardness is low. The cooling speed required for the formation of spherical pearlite is generally controlled at 10~30℃/h. In order to ensure the quality of spheroidization, the cooling speed of 15~20℃/h can be used as the standard. In the actual production process, it is greatly influenced by the furnace insulation performance and room temperature. GCr15 bearing steel annealing, GCr15 steel at 780 ℃, the transformation of pearlite to clinopyroxene in 5 ~ 10min can be completed. Even if the forging organization has a fine mesh carbide, such as 1h below 800 ℃, can also be basically eliminated. However, taking into account the size of the part, effective wall thickness, loading method, the amount of loading and furnace power and other factors, the need to ensure that the basic transformation of the tissue required to complete the shortest time. The purpose of using graded quenching is to reduce the deformation and cracking of the part. Because the isothermal near the M point can make the center of the part and the surface temperature difference is reduced, the metal section due to shrinkage inconsistent thermal stress is greatly reduced. Bearing ring grading temperature below the M point, usually between 120 ~ 200 ℃.

● Technical Parameters
