advantage of deep groove ball bearings industry 双列角接触球轴承|3056轴承-pg电子官方网站

1, under normal conditions, the efficiency of the hydrodynamic lubrication of rolling bearings and bearing equivalent, but higher than the number of hybrid-lubricating bearing;
2, radial clearance is relatively small, angular contact bearings are available to the heart of available preload preload to eliminate backlash, high running accuracy;
3, for the same size shaft, the rolling bearing width smaller than the sliding bearings, can axially compact structure of the machine;
4, most of the rolling bearing can be simultaneously subject to radial and axial load bearing composite structure so simple;
5, consume less lubricant, easy to seal, easy to maintain;
6, no useful for non-ferrous metals;
7, the high degree of standardization, mass production, low cost;
