Angular Contact Ball Bearings On The Use Of The Check
Machine shaft parts, especially spindles, are generally thrust ball bearings assembled into one, and a high rotational speed, and sometimes will produce a very high heat. This phenomenon if not removed, will result in angular contact ball bearings overheat, and the corresponding parts of the machine temperature and thermal deformation, serious cause spindle and tailstock is not high, which not only affects the precision and accuracy of the machine itself and bearings will burn out.
Rated fatigue life, refers to a group of the same type of bearing, running under the same conditions, 90% of the angular contact ball bearings from total number of revolutions of rolling contact fatigue spalling due to appear. At constant speed, more than the rated fatigue life of the total running time.
