Analysis on preload target and precautions of deep groove ball bearing

It is not allowed to punch with force, directly knock the bearing with a hammer, and transfer pressure through the rolling element.
Try to use special tools and try to avoid using cloth and short fiber.
Even if the invisible smile dust enters the bearing, it will increase the wear, vibration and noise of the bearing.
When taking the deep groove ball bearing directly by hand, fully wash the sweat from your hands and apply high-quality mineral oil before operation. Pay special attention to rust prevention in rainy season and summer.
Under some special operating conditions, the service life of deep groove ball bearing can be longer than that of traditional calculation, especially under light load. These special operating conditions are the surface damage that may be caused when the rolling surface (track and rolling parts) is effectively separated and limited by a lubricating oil film. In fact, under ideal conditions, the service life of the so-called permanent deep groove ball bearing is not impossible.
(1) While accurately determining the positioning of the radial target and axial target of the shaft, lift and stop the runout of the shaft.
(2) Improve the rigidity of the bearing. The slave shaft bearing of the machine tool and the deep groove ball bearing for the pinion of the bicycle differential mechanism.
(3) The purpose of preventing the axial mark from vibration and homophony due to resonance. Bearings for small motors.
(4) Lift and stop the torsional sliding, revolution sliding and rotation sliding of the rolling element. High speed torsion centripetal thrust bearing, thrust ball bearing.
(5) Take the ferrule and connect the accurate position of the rolling element. When the thrust ball bearing and thrust self-aligning roller bearing are used as the shaft.
