Hey! more details of bearing ntn you want
Regarding the choice of bearing ntn structure, I will continue to introduce you.
1. Limit speed and bearing ntn structure
The allowable limiting speed of the rolling bearing, in addition to the bearing structure, also varies depending on the cage structure, material, bearing load, lubrication method, and cooling status. Generally, the oil bath lubrication condition arranges the bearing structure in the order of maximum rotational speed.

2. The inclination of the inner and outer rings and the bearing ntn structure
The deflection of the shaft due to the load, poor accuracy of the shaft or housing, installation errors, etc., cause tilting between the inner ring and the outer ring of the bearing ntn. The allowable tilt angle of the bearing. Due to the use of bearing structure conditions vary. However, it is usually the smallest value below 0.0012 radians (4').
When it is expected that the inner ring and the outer ring will have large tilt, automatic self-aligning ball bearings, self-aligning roller bearings, and spherical bearings with seats are used
Bearing structure.
The allowable tilt angle of the bearing is described in the small preamble of the various bearing ntn size tables.

3. Rigidity and bearing ntn structure
After the rolling bearing ntn receives the load, the contact portion of the rolling element and the raceway is elastically deformed. The rigidity of the bearing, from the bearing load, the inner ring, the outer ring, and the rolling elements.  The ratio of elastic deformation is determined.
The spindle of the machine tool, etc., in combination with the rigidity of the bearing, also increases the rigidity of the bearing ntn. Therefore, the roller bearings ntn that have less deformation than the ball bearings under load are selected.
In addition, the preloading method is used in advance, so that the clearance of the bearing is used in a negative state and the rigidity of the bearing can be improved. Suitable for radial thrust ball bearings, tapered roller bearings.
