Discussion on the structure of large rolling bearings

The intermediate rotating element on the outer ring of the bearing is usually designed to enhance the stability and load-bearing capacity of the bearing. It can distribute and balance the load on the outer ring of the bearing, effectively reducing friction and wear, and improving the bearing’s lifespan and operational efficiency. In rolling bearings, the rotating element in the middle is usually a roller or sphere, whose function is to transfer loads between the inner and outer rings of the bearing and to reduce friction. It can withstand loads from the rotating axis, as well as radial and axial loads from different directions. Furthermore, the intermediate rotating element can also balance the force distribution within the bearing, reduce vibrations and noise, and improve the smooth operation of the bearing. Therefore, the intermediate rotating element on the outer ring of the bearing plays a key role in large rolling bearing structures. .

Is this a rolling bearing or a sliding bearing?
