Internal and deep groove ball bearings used in conjunction with the thrust ball bearings play what role, can not that thrust ball bearings?
If the axial force is large, the angular contact ball bearing or tapered roller bearing shall be subjected to axial force in the invisible position
Because it is not cancelled support bearings.The shaft may be vertical, and if the axial force is small, it can be carried by a deep groove ball bearing.
You can't cancel the drawings from your drawings. The larger ones are invisibleDeep groove ball bearings are capable of bearing both radial and axial forces in two directions, but the axial forces can not be very largeFrom the above figure it is impossible to determine whether there are two directions of axial forceThat from the above structure (that can't see all drawings), deep groove ball bearing is to support the shaft rotation, but thrust ball bearings may be supporting parts (the large shadow) and axis rotate 90 degrees.
