NSK angular contact ball bearing characteristics: this type NSK ball bearings can bear radial load and axial load.The peed is high will be; contact angle has 15 degrees, 25 degrthe , 40 degrees three types, the larger the contact angle, the higher the axial bearing capacity. The high precision bearing and high speed bearings typically take 15 contact angle. And under the action of axial force, the contact angle will increase; generally the inner ring or outer ring have lock, and the inner, outer ring can not be separated. When outer ring be heated expansion, the angular contact ball bearings will assemled with the inner ring,the rolling body,and the cage. The ball capability of angular contact ball bearing is larger than deep groove ball bearings.The NSK bearing load ratings is the largest in all ball bearings, strong rigidity, steady operation; The bearing can use mutual displacement of the inner, outer ring to adjust the radial clearance. Often bring a preload, in order to improve the rigidity of the bearing.
