Deep groove ball bearing axial load calculation，Deep groove ball bearing theory does not derive axial force, but the actual application process will be subject to a slight axial force, because it has a certain alignment effect, after the axial force disappears, will return to the original position.
Deep groove ball bearing axial load calculation，The size of the axial force to have a connection with the actual working environment, by the axial force after the force of the ball bearing equivalent to a contact angle, into a similar angular contact ball bearing, this axial force also and the bearing itself clearance, groove rate radius has a great relationship.
Especially the clearance, the larger the clearance, the greater the range of movement of the steel ball in the axial position, that is, the larger the axial clearance, the greater the axial force that can be withstood, but the clearance can not be blindly large.
Deep groove ball bearing axial load calculation，Axial force should be much smaller than radial force, as for how to calculate the specific, because the contact angle can not be predicted, so there is no way to know.
If the bearing by radial load at the same time also need to continue to be axial load, deep groove ball bearing selection is unreasonable, because the continuous axial force will reduce the life of deep groove ball bearing, according to the speed and other industrial and mining can choose angular contact ball bearing or tapered roller bearing, if need two-way by axial force can also choose four-point contact ball bearing, double row tapered roller bearing or double row angular contact ball bearing.
If it is pure axial load, then the co of the bearing should be greater than 2x300nxs (safety factor), if it is compound load, to see the relationship between fa/fr, calculate the equivalent load, according to the equivalent load to choose bearings.
If the axial load is really 30n, that is very light, choose the inner diameter is 3 dgbb can, you instead have to pay attention to the minimum load of the bearing.
