6009 c3bearing applications  

6009 c3 bearing can be used for: refining equipment, flash drying machine, calender, knitting machine, pressing machine, handle, iron machine, pre-treatment equipment, metal welding machine, dyeing and printing machinery and equipment, grinding machine, electrodialysis devices, multiple reduction machine, drying equipment, drying machine, beverage production equipment, the hybrid heat exchanger, marking a car,  And so on.  
The purpose of 6009 c3 ball bearings is to determine the relative position of two parts (usually a shaft and a bearing seat) and ensure their free rotation, while transferring the load between them.  At high speeds (as in gyro ball bearings), this use can be extended to include free rotation with almost no wear in the bearing.  To achieve this state, two parts of the bearing can be separated by an adhesive fluid film called an elastohydrodynamic lubrication film.  

Clearance control of 6009 c3 deep groove ball bearings:
Abstract: In order to solve the problem that radial clearance is usually controlled by axial clearance in the production of 6009 c3 deep groove ball bearings, and the radial clearance is out of tolerance after fitting, the radial clearance range in axial clearance is calculated by strictly controlling the accuracy of inner and outer channels and steel balls, and the lower limit value remains unchanged, and the upper limit value is reduced by 15%.  The axial clearance obtained by this method is the actual radial clearance after the reference control.
