News of how to choose roller bearing in INA bearings catalogue

Introduction of basic elements of INA rolling bearing in INA bearings catalogue.
In the design of the new spindle, before selecting the INA bearing in INA bearings catalogue, consider the main shaft performance parameters, determine the most critical performance, and then enter the further probe. (including spindle speed, spindle precision, spindle rigidity, spindle life, main shaft heating, spindle reliability)
After determining the main shaft parameters, the actual size of the main shaft (axial diameter, length, bearing span) is determined.
According to the bearing form (ball or roller bearing), go (to match the number of columns), drive mode (belt) within, gears, motors, motor, lubrication, grease, oil and gas, oil mist, spray) set of parameters such as spindle to determine its structure.

1. Bearing radial load.
The main bearing of the radial load of INA bearing is the centripetal bearing. The nominal contact Angle of such bearing is a0<=450. The same roller bearing can bear more radial load than ball bearing.
The N and NU cylindrical roller bearings can only bear radial load, while other types of radial load can withstand radial load and axial load.
2. Axial load of bearing.
Main bearing axial load bearing generally is thrust bearing, its nominal contact corner a0>450. Thrust bearings and thrust angular contact ball bearings can withstand one or both directions at the same time depending on the structure. The thrust roller bearing and thrust aligning roller bearings are preferred when the bearing capacity is particularly high.
Thrust aligning roller bearing and one-way thrust Angle contact ball bearing can withstand axial load and radial load at the same time. Other thrust bearings can only bear axial load.
3. The bearing's own length compensation.
Bearing a shaft and bearing usually adopt a combination of fixed bearing and moving bearing. The length error and thermal expansion of the offset shaft of the floating INA bearing.
The NU and n-type cylindrical roller bearings are ideal for moving bearings, which can compensate for the length. The inner and outer rings of the bearing can be used tightly.
4. Length compensation of sliding fit.
Non-separable bearings can also be used as moving bearings. This type of bearing is used in one of two rings, with no axial fixed surface. Therefore, a ring of the bearing can be operated on its supporting surface.
After determining the size and type of precision bearings, consider the specific design of bearing.
Considering the bearing fatigue life, rigidity, heat and other factors, select the most suitable bearing clearance (preload).
Because of the bearing clearance and preload, the performance of INA bearing is the most critical, and the more high-speed operation, the more critical, so it must be considered carefully. Choose not at that time, there will also be early damage or sintering problems. It is necessary to go from step 4 to step 3, or from step 4 to step 2.
After determining the main shaft structure design, consider the necessary conditions for the actual installation.
The mounting shaft of the high precision bearing and the precision of the bearing pedestal, the tolerance, the tightening force required for fixing the fixed nut, the pre-load of INA bearing after the actual installation and the confirmation of the internal clearance.
