How to judge INA edabearings are available
Most favorable price : sales@hellerbearings.com
First, when INA bearing a uniform and continuous "hissing" the sound by rolling in and outside the graph rotation and vibration, including metal sound with irregular and speed. ". The general performance of the bearing grease is insufficient, should be added. If the equipment down time is too long, especially in the cold winter, the edabearings running sometimes issue "hissing rustling" sound, and the bearing radial clearance becomes small, lubricating grease penetration becomes small. Should be appropriate to adjust bearing clearance, the replacement of new grease penetration point.
Second, when the INA edabearings in continuous "clang clang" sound in a homogeneous periodic "Ho," the sound is caused by the roller and the raceway scars, trench, rust spots. Cycle and the bearing is proportional to the speed of sound. Replace with INA bearing.
Third, when a INA bearing a discontinuous "Geng Geng" the sound is caused by the holder or the inner and outer rings rupture. Replace bearing down immediately.
Fourth, when the bearing from irregular, uneven "Tsatsa" the sound is caused by bearing into iron, sand and other impurities. Sound intensity is small, no contact with the revolution. Deal with the bearing cleaning, re fat or oil.
Fifth, see the INA bearing a continuous and irregular "rustling" sound the general import bearing inner ring and shaft fit too loose or outer ring and the bearing hole with too loose relationship. Sound intensity is larger, check with the relationship between coping bearing, found that the problem timely repair.
INA judgment of the edabearings is available, is mainly considered during bearing damage, mechanical properties, the importance, operating conditions, until the next maintenance decision. If you have the following defects can not use, the replacement of the new edabearings must be. The inner ring, outer ring, rolling body, cage there any cracks or gaps.
(1) ring, rolling body fault on any one.
(2) the rolling road surface, edge, scroll marked card injuries on the body.
(3) the retainer wear significant or significant relaxation of rivet.
(4) the raceway surface, rolling rust body, has the wound.
(5) the raceway surface, rolling there is serious indentation and trace.
(6) the diameter of the inner ring or outer diameter surface creep significantly.
(7) discoloration caused by the heat of the obvious.
(8) grease sealed edabearings, seals or shields damaged obviously.

Now that you know the INA edabearings under the normal state of sound, then we can according to these as standard to judge the cause of abnormal circumstances:First, when INA bearing a uniform and continuous "hissing" the sound by rolling in and outside the graph rotation and vibration, including metal sound with irregular and speed. ". The general performance of the bearing grease is insufficient, should be added. If the equipment down time is too long, especially in the cold winter, the edabearings running sometimes issue "hissing rustling" sound, and the bearing radial clearance becomes small, lubricating grease penetration becomes small.
