Bearing configuration

In general, the shaft is supported by two rolling bearings. When considering the deep groove ball bearing configuration, the following items must be studied.
(1) The expansion and contraction of the bearing due to temperature changes.
(2) Ease of installation and disassembly of bearings.
(3) Tilting of inner and outer rings due to shaft deflection and mounting errors.
(4) Rigidity and preloading methods that include the entire rotating system of the bearing.
(5) Load and conduct in the most suitable position.

deep groove ball bearing
Fixed end bearing and free end bearing
When configuring the deep groove ball bearing, use one as a fixed-end bearing. In the fixed end of the bearing to choose affordably. Radial load and axial load bearing. Bearings other than fixed-end bearings that can withstand radial loads. Free end bearings. Bearings other than fixed-end bearings are used as free-end bearings that are subjected to radial loads. In this way, the expansion and contraction of the bearing due to the temperature change are solved. Moreover, it is also possible to use axial direction installation adjustment of location.
If there is no sufficient solution to the shaft expansion and contraction due to temperature changes, the bearing will be abnormal. The axial load becomes the cause of the early damage of the bearing.
Free end bearings, cylindrical roller bearings with an inner ring and outer ring that can be separated and axially movable (NU, N-type, etc.) radial needle roller bearings. This type of bearing is easy to install and remove. Use non-separable bearings for self.
From the end, usually, the outer ring and the bearing box fit as a clearance fit to eliminate the expansion of the shaft during operation. Can be excluded from the inner ring and bearing mating surface.
In the case of short deep groove ball bearing intervals and little shaft telescoping effect, the bearing will only bear the load in one direction. Thrust ball bearings, tapered roller bearings, and other two use. Axial clearance after installation (looseness in the axial direction). Adjusted by nuts and washers.
