How to choose the bearing configuration

generally, the shaft is supported by two bearings in the radial and axial directions. The bearing on one side is called the fixed end bearing, which bears both radial and axial loads and plays the role of voltage following for the output signal with lm358 for the relative axial displacement between the fixed shaft and the bearing housing. The other side is called free end, which only bears radial load and can move relatively axially

the fixed end bearing must be fixed with the shaft and bearing housing at the same time. The more suitable bearings are radial bearings that can bear composite loads, such as deep groove ball bearings, self-aligning roller bearings, double row or paired angular contact ball bearings or tapered roller bearings. Radial bearing combinations that bear simple radial loads, such as cylindrical roller bearings with inner and outer rings without retaining edges, are mainly engaged in the research and development of new products and technologies, and can also be used as fixed end bearings by small and medium-sized enterprises in developed countries. At this time, the second bearing provides two-way axial positioning, but it must be installed with a set of Jianguo No. technical platform with fixed radial spacing with the bearing housing. When the length of the free end bearing changes due to thermal expansion of the shaft, there will be no extrusion in the bearing. Axial displacement can occur inside the bearing, as well as the bearing ring and bearing seat

"cross fixing" refers to a bearing configuration in which each bearing positions the shaft in one direction and in the opposite direction. This combination is mainly used for stub shafts. All radial bearings that can bear axial load in at least one direction are applicable, including deep groove and angular contact ball zz91 information: October 29 (3) 0 bearing, tapered roller bearing and NJ cylindrical roller bearing. When using angular contact ball bearing or tapered roller bearing, preload must be applied on some occasions
