1, ntn bearing nature of the noise datantn bearing nature of noise is the use of modern processing technology made bearings will occur,NTN Bearing determined the structure of the noise itself.Nature of acoustic noise can be divided into roller, ball impact and jarring sound of three kinds of sound, are as follows:(1) ntn roller bearings roller sound and control noise when running NTN Bearing imports,

1, ntn bearing heat knowledge  ntn bearing the core component, the spindle cell component usually μm-level precision, such as the beating is generally 1 ~ 3μm, spindle stiffness generally 100-300N/μm, therefore, spindle precision of the various parts and their deformation is small. However, the high-speed operation, the bearings much heat, resulting in a high bearing temperature rise and cause thermal deformation.

ntn rolling bearings is the mass production of machine parts, and manufacture of precision is very strict for a high degree of technical specialization, thus readily available for most bearing varieties, should be purchased more cost-effective than repair, and only in the following situations Next, before considering the repair bearings, namely:1.ntn bearing a slight injury, such as inventory

Identification of the Quality of the sound description:Irregular use of hearing to identify the operation is a very common method. For example: With the electronic stethoscope to check does not feel a part of the normal noise often experienced operators to use the method.ntn bearings are well connected to the switch if the state will issue a muffled whining sound. If issued a sharp hissing sound,

Ntn roller bearings on the metal shavings and other foreign bodies are particularly sensitive, ntn bearing Once foreign body, will result in large intermittent vibration and noise, will lead to early damage. In addition, ntn roller bearings impurities due to metal clips, also prone to the possibility of early damage. Even if the damage does not occur early, rolling ntn bearing life there are certain limits. In short, ntn roller bearings life shorter than the slide ntn bearing

More top tight radial method used in radial load bearing tapered hole, the typical example is the double row precision cylindrical roller bearings, using nuts to adjust the tapered journal bearing relative to the axial position, so that within circle have the right volume by radial expansion of the negative clearance, the method for machine tool spindle and multi-jet engine.Axial preload law tightening and positioning in general can be divided into two constant pressure preload.
