Bearing temperature.
Installed SKF bearing parts allow operation of the agency, a certain temperature is normal when stroking institutions housing should not feel hot, otherwise the bearing temperature.
Bearing temperature: the lubricant quality does not meet the requirements or deterioration, lubricant viscosity is too high; institutions assembly too tight (lack of space); tight bearing assembly; rotation of the bearing seat on the shaft or shell; overload large; bearing retainer or rolling body fragmentation.
Bearing noise
Rolling bearings allow minor operation sound work, if the noise is too large or unusual noise or crash, SKF bearings failed.
Rolling bearing noise is more complex, one of the bearing inner and outer mating surface wear. This kind of wear and tear, with the relationship of the destruction of the bearings and housings, bearings and shaft axis deviation from the correct position to produce abnormal noise in high-speed movement in the shaft. When SKF bearing fatigue, surface metal flaking, also cause bearing radial clearance increased abnormal sound. In addition, insufficient bearing lubrication, a dry friction bearings broken will produce an unusual sound. The retainer loose damage, bearing wear Songkuang, will produce abnormal noise bearing damage.
