1206 1206K 111206 Self-aligning Ball Bearing

Self-aligning ball bearing outer raceway processed into spherical, it has self-aligning properties. Mainly used to bear radial load, in bear radial load at the same time, also can bear a small amount of axial load, but generally can't bear pure axial load, its limit rotational speed is deep groove ball bearing is low. This kind of bearing used in load more vulnerable to under the action of bending double supporting shaft, and double supporting seat hole can't guarantee strict coaxial degree components, but the inner ring of the center line and the center line of the outer of the relative gradient must not exceed 3? . This kind of bearing because the ball and roller way contact area is small, and the load capacity is low, short service life, and will be self-aligning roller bearing is replaced trend.
