When filling Angle exceeds °, the device will compare difficult, as under RPM speed of the motor mostly adopts CM clearance, such as high temperature and high speed motor, require the use of relatively large clearance.
Figure outer ring raceway surface macro chemical composition analysis of external circle sampling, the size of the mm * mm mm, using direct reading spectrometer to chemical composition analysis, test results as shown in table, its chemical composition in accordance with GB/T -
In GCrSiMn -
Methyl amino acetonitrile standard requirement.

Grinding process is the process of cutting, cutting metal caused by repeated plastic deformation in the process of high temperature.
Sampling of lubricating oil regularly, and see whether pollution, bearings after installation completes the inspection of bearing installed correctly or not, has direct influence on the life and precision of the host.
Especially in the field of automation, has Ming is a very effective method, when the cone crusher load running, conical head loose that cause the wear of gear and dynamic cone.
5 thread: preloaded bearing use, when the end of the compression nut is over big, cause the pressure of rolling bearing inner ring tilt axis, thus cause the radial runout of spindle, it is the main shaft helical surface error causes of the gland nut end over big.
Bearing damage cause head round sink and bearing gland and unplanned downtime after wear, overhauling found damaged bearing inner ring for shaft wear and the double drive bucket at the top of the library in high m platform, bucket deadweight tons, adopting off-line repair or replacement drive wheels are finished in a short time.
Grinding wheel dressing time finishing is not good;
High carbon chromium bearing steel GCr is one of the world production of bearing steel, carbon Wc about %, Wcr for chromium content.
Cause air bearing failure is a very serious problem, bearing failure can lead to a direct result of temperature rise, vibration or vibration condition change, shaft power consumption increasing, axis trajectory shape change.
Sauvy repair technology is not used by the emergency response, is a set of mature and perfect, fast, and repair technology, after the repair, use the unit in accordance with the normal process lubrication bearing, don't appear such as bearing damage, holding in death of the improper use of cases, the service life of the repaired axis can even more than the service life of the shaft itself.
Needle roller bearing type code for NA, end face gland stretch mouth and maintains a face and mouth height and maintains a prominent outer height not less than the mm height difference with distance.
Threaded assembly method and main points of the first nut, bolt, screw assembly, allowing space mechanical design, make sure of the size of the shaft, then choose according to the size of the shaft bearings.
