Bearing allows at work has a slight running sound, if the noise is too large or unusual noise or impact sound, then thrust spherical roller bearing is faulty.
1, the bearing group to produce industry at a world class level, strong bearing steel quality and life of the bearing. Ball and roller rolling elements roll in to operate also affects the quality of spherical roller thrust bearings, which cannot have a direct relationship to the proper functioning of the bearing.
2, bearing selection, influence was one of the main bearing is not operating properly, now with the metallurgical technology continues to improve, is the consummate bearing quality of bearing steel has also been greatly enhanced, now bearing due to the material causes of quality problems had been resolved. Grease selection of thrust spherical roller bearing is not operating properly, and leave anything on the market today, which includes special lubricants for bearings, it has also encouraged the bearing is not operating properly, and the bearing itself does not make much difference, so kind of brand to suffer to pay for, the culprit is the lubricant.
3, manufacture of bearings, bearing early due to selection not functioning
Bearing noise causes are complex, one is the inner and outer rings of bearing surface wear. Because of this wear, damage bearings works with shell, rolling bearings and shaft, causes the axis deviates from the correct location, the axis in abnormal sound when fast-moving. When bearings are tired, its surface metal flake, also makes thrust spherical roller bearing radial clearance increase the noise. In addition, insufficient bearing lubrication, formation of dry friction and bearings broken produces abnormal noises. After the bearing wear loose, loose cage damage, will also have an abnormal sound.
