Aligning ball bearing inner ring generally have two raceways, installed two rows of balls, but only one bearing outer ring raceway, and the large curvature of the inner spherical center of curvature is the center of rotation of the bearing, the radius of curvature It is spherical radius, it can contain two balls and the inner ring. Therefore, the inner ring and the ball raceway in the outer ring rotates around the center of any, it has a self-aligning performance.

      Bearing cage, usually by the cold-rolled carbon steel plate stamping integral or separate daisy-shaped rosettes. Greater self-aligning ball bearings, but also useful solid drilling cage.
      These bearings allow the inner ring and the outer ring of the rotary shaft and the machine housing a certain angle at work, which ranges between 1.5 degrees -3 degrees. It can automatically compensate concentricity error due to deformation of the shaft flexing and the housing produced for bearing seat hole can not guarantee strict concentricity of the parts, such bearings are mainly used for agricultural machinery, blowers, paper machines, textile machinery , woodworking machinery, overhead crane go on wheels and drive shaft.
      Press-aligning ball bearing structure type, it is only suitable for pure radial load to bear, but sometimes it can withstand a small amount of axial load.
      Cylindrical hole aligning ball bearings 10000 type.
      Tapered bore (taper 1:12) aligning ball bearings 10000K type.
      Mounted on an adapter sleeve aligning ball bearings 10000K H type, such bearings are mainly used without shaft shoulder of the optical axis (the axis precision machining, dimensional tolerances according to h9. Shape tolerance by IT5). Installation and removal more convenient, with adapter sleeve can also adjust the bearing radial clearance.
