Self-aligning ball bearing

Self-aligning ball bearing is two race between inner ring and groove for spherical outer ring, equipped with balls of ball bearings.
On the surface of the outer ring raceway curvature center and bearing center consistent, so with automatic self-aligning ball bearing the same tone heart function. In there was a deflection axis, a hood, can automatically adjust, not to increase the bearing burden. Spherical roller bearings can withstand radial load and two direction axial load. Large radial load capacity, suitable for heavy load and impact load. Inner circle diameter is tapered bore the bearing, it can be installed directly. Or the use of set cover, remove the cylinder installed on the cylinder axis. Keep rack stamping steel cage, polyamide forming keep frame and copper alloy car cage.
Self-aligning ball bearing with two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins. Characterized by outer ring raceway is spherical shape, have so can compensate concentricity and deflection built into the error of the self-aligning ball bearing, but it shall not exceed 3 degrees between inner ring and outer.
May withstand the bigger radial load, and at the same time also can absorb a certain amount of axial load. This kind of bearing outer ring raceway is spherical shape, so has a self-aligning performance, when the axial stress bending or leaning and make the center line of the center line of the inner ring and outer ring relative tilt is not more than 1 ° ~ 2.5 °, bearing can still work.
Self-aligning ball bearing inner hole has two kinds of cylindrical and conical. Conical taper of inner hole of 1:1 2 or 1:30. In order to strengthen the bearing lubrication performance in annular groove on the bearing outer ring and three oil hole.
