● Introduction
Ball bearing 6213 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, bearing radial clearance is divided into original clearance, installation clearance and working clearance. Usually, the original radial clearance of the bearing is larger than the clearance when the bearing is working. The material of the bearings is GCr15, which is in accordance with ISO 683-17:2014 and has a high elastic limit and good machinability. The bearings are normalized, annealed, quenched and tempered to the hardness of HRC60~65. Bearings are widely used in roller skates, motors, engineering machinery, machine tools, agriculture and other fields.
● Production Details
There are two main types of grinding and shaping methods for each surface of bearing rings: trajectory method and shaping method. Since the surface of the collar is a rotary body, the shape of the forming surface wire is by the trajectory method, and is a circle located in the plane of the direction of rotation of the collar. Improve the quality of forgings before rolling and expanding, so that the outer diameter surface of forgings will be filled with the cavity of rolling wheel from large end face to small end face during rolling and expanding process, and when the cavity is filled, the outer diameter size will reach the requirement and stop rolling and expanding. Improve the quality of forgings before rolling and expanding, keep certain rolling temperature, especially the temperature at the end of rolling and expanding should not be too low. Within the range of processing requirements. Improper installation of the electric spindle on the machine tool (such as loosening, unlevel axis, etc.), crashing or knocking with tools during use will cause bending and deformation of the spindle or grinding wheel joint, resulting in loss of accuracy of the electric spindle and vibration, which will affect the quality of the inner surface of the workpiece due to poor dressing of the grinding wheel, and will easily produce a variety of vibration patterns.

● Products Precision
National standard for bearing inner diameter (d) and outer diameter (D) provides two kinds of tolerance: one is the maximum value of d (or D) and the minimum value of the allowed limit deviation, its main purpose is to limit the amount of deformation. Second, the bearing collar any cross-section within the measured maximum diameter d real max or (D real min) and the minimum diameter d real min (or D real min) of the average limit deviation (that is, a single plane average internal, external diameter deviation △ dmp and △ Dmp), the purpose is to be used for the bearing fit.

● Noise and Vibration Level
Rolling bearings themselves do not produce noise. What is commonly perceived as "bearing noise" is in fact the acoustic effect of the bearing vibrating directly or indirectly with the surrounding structure. This is why in most cases, bearing noise is not just a problem of the bearing itself, but of the entire bearing application.
