● Introduction
6218 2RS bearing belongs to single row deep groove bearings. The bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cage. 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 material of the bearings is GCr15, which is in accordance with ISO 683-17:2014, quenched (oil quenching) at 830~860°C and tempered at 150~180°C (2~4h). Bearings are widely used in industrial pumps, motors, construction machinery, agriculture, machinery industry, machine tools and other fields.
● Production Details
If the inner diameter size is too small and the outer diameter size is too large, it will increase the grinding volume and reduce the productivity: on the contrary, it will affect the grinding quality or leave the black skin of turning. The different width sizes of bearing rings also affect the grinding quality, productivity and service life of grinding wheels. If the width size is small, the end face will not be ground and will be scrapped.

● Precision Standards
In order to meet the support accuracy, bearing performance and life requirements, the standard also specifies the mating parts of the mating parts of the form tolerance and surface roughness. Select with, can be based on the standard recommended selection, can also use the method of estimation to calculate the required minimum interference, and then according to the minimum interference with the corresponding selection. When the interference fit on the clearance is relatively large, should estimate the impact on the clearance range.

● Noise and Vibration
Vibration caused by rolling surface roughness of bearing parts. The roughness of rolling surface of bearing parts also affects the vibration of finished bearings. When the rolling surface roughness Ra value is greater than a certain value, the vibration value of the finished bearing will rise significantly. If there are irregular grinding marks on the rolling surface, the vibration of the finished bearing will be more influenced.
