Compared with sliding bearings, compared to the advantages of deep groove ball bearings and sliding bearing, deep groove ball bearings in the inferior one, under normal conditions, the efficiency and fluid power lubrication of rolling bearings bearing considerable but more mixed lubrication of bearings to be higher; a poor payload capacity to withstand shockschina bearing supplier; 2, the radial clearance is relatively small, radial angular contact bearings available preload preload available to eliminate the clearance, high running accuracy;, high-speed heavy load bearing lower life; 3 , for the same size shaft diameter, the width of the rolling bearing slide bearing, the axial structure of the machine can compact; bearing factory3, vibration and noise; 4, most of the rolling bearing can be subject to both radial and axial load, so the bearing combination of simple structure; 4, the radial size than plain bearings;, consume less lubricant ease of sealing, easy to maintain; do not need a usef ul non-ferrous metals; 7, the high degree of standardization, mass production, low cost; bearing factory in china
