Six notices of selecting NTN Bearing
Most favorable price : sales@hellerbearings.com
NTN Bearing installation space is limited, focus on the axis rigidity and strength due to the design of shaft, it is generally first determine the shaft diameter, NTN Bearing inner diameter. Scroll NTN Bearing series and types of a variety of sizes.
2, the inner and outer ring of the relative tilt
NTN Bearing inner ring and outer ring relative tilt of the factors (such as the accuracy of the load caused by shaft deflection, shaft and housing to poor or installation error), and able to adapt to the conditions of use of NTN Bearing type. If the inner ring and outer ring of the relative tilt is too large, NTN Bearing damage will generate the internal load.
3, the size of the load, the direction and nature of the consideration
NTN Bearing the load capacity of the basic rated load. NTN Bearing load varied, such as the size of the load, only the radial load, axial load is unidirectional or bidirectional, vibration, or the degree of impact. General, the same inner diameter of NTN Bearing radial load capacity is incremented in the following order: deep groove ball bearings <angular contact ball bearings <cylindrical roller bearings <taper roller bearings <Spherical Roller Bearings
4, installation and removal, the periodic inspection methods
When frequent assembly and disassembly of the frequency and disassembly of the installation and removal, periodic inspection such as assembly and disassembly, use the inner ring and outer ring separable cylindrical roller bearings, needle roller bearings and tapered roller bearing is more convenient. Roller bearings to withstand load raw deformation than ball bearings. NTN Bearing preload (negative clearance) can improve the rigidity of this method is applicable to the angular contact ball bearings and tapered roller bearings.
5. Speed
NTN Bearing speed limit value basis, the speed limit. NTN Bearing the limits of speed not only take also limited the type of NTN Bearing NTN Bearing size, to keep the aircraft type, accuracy class, load conditions and lubrication methods, the choice must take into account these factors.
6, rotation accuracy
Dimensional accuracy and rotation accuracy of the NTN Bearing NTN Bearing type standardized by the GB. Machine tool spindle, gas turbine and the control of the machine requires high rotation accuracy, high speed and low friction, should be used more than five precision NTN Bearing.
, Is very useful to fully grasp the conditions of use of the NTN Bearing NTN Bearing type is selected.
