● Introduction
6204 2RS haigh quality Bearing belongs to single row deep groove bearings. It is produced by our company in accordance with the national standard GB/T 276-2013, and the bearing‘s groove is super-finished. The company is committed to providing customers with stable and competitively priced high quality bearing products. Bearings are mainly subjected to pure radial load, and can also be subjected to radial load and axial load at the same time. The load is mainly carried from one ring to another by the rolling element. The bearing's load capacity is determined by the load capacity of the rolling element. The material of bearing cage is 08Al. The cage is generally made of steel plate by stamping at normal temperature with the use of mold, and the shape, dimensional accuracy and surface quality of the cage can be guaranteed by stamping molding processing. Bearings are widely used in industrial pumps, pumps, transportation vehicles, tractors, roller skates, automated office machinery and other fields.
● Production Details
Will workpiece quenching cold using cold treatment process, it can reduce the organization of the residual austenite, slightly improve the hardness of the parts. But also pay attention to the amount of austenite is not too small, otherwise it is not conducive to the improvement of bearing life. The worst quality of the turning process will be detrimental to the subsequent processes, causing different degrees of reimage errors, which will affect the machining accuracy and productivity, and some errors cannot be repaired, resulting in waste of manpower, material and working hours and economic losses. Steel blue brittle fracture under the temperature of the material according to the color of the material section fracture to judge, when the temperature is low dry 280 ℃, the mouth is white or yellow, 280 ℃ is purple, 300 ℃ is dark blue, 330 ℃ is light blue, higher than 330 ℃ is gray.

● Bearing Quality
Bearing maximum radial clearance measurement value and the minimum radial clearance measurement value determination method: use the stopper piece along the roller and raceway circumference measurement, rotate the collar and roller cage assembly a week, in three consecutive rollers can pass the stopper piece of the maximum thickness for the maximum radial clearance measurement value. In three consecutive rollers can not pass the minimum thickness of the plug gauge piece for the minimum radial clearance measurement value. Take the arithmetic average of the maximum and minimum radial clearance measurement value as the radial clearance value of the bearing.

● Bearing Inspection
Rolling bearing noise generated by the reason is more complex, one is the bearing inner and outer ring with surface wear. Due to this wear, the destruction of the bearing and shell, bearing and shaft fit relationship, resulting in the axis deviated from the correct position, in the shaft in high-speed movement to produce a strange. When the bearing fatigue, its surface metal flaking, will also make the bearing radial clearance increases to produce strange noise. In addition, bearing lubrication is insufficient, forming dry friction, as well as bearing broken will produce abnormal sound. Bearing wear loose, cage loose damage, will also produce abnormal noise.
