Aligning ball bearings: two raceways in the inner and outer ring raceways between spherical, equipped with a spherical ball bearings. Outer ring raceway curvature center and bearing center line, the
 
To have a self-aligning ball bearing with the same self-aligning feature. In the axis, deflection occurs when the shell can be automatically adjusted without increasing the burden bearing. Spherical roller bearings can bear radial load and axial load in two directions. Radial load capacity, suitable for a heavy load, impact load conditions. Inner diameter is tapered bore bearings can be installed directly. Or using an adapter sleeve, remove tube installed in the cylinder axis. Cage with steel stamping cage, forming polyamide cage and copper alloy machined cage.
Aligning ball bearings with cylindrical bore and tapered bore two structures, and retainers made of steel sheet or synthetic resin. Which is characterized by the outer ring raceway spherical shape, with auto-Mind, can compensate for misalignment and shaft deflection aligning ball bearings into making errors, but the inner and outer rings relative inclination of not more than 3 degrees.
[1] can withstand higher radial load, but also bear certain axial load. This kind of bearing outer ring raceway is spherical shape, aligning it with the performance, when the axial force leaving the inner bend or tilt tilted relative to the center line and the center line of the outer ring does not exceed 1 ° ~ 2.5 °, the bearing can still work .
Aligning ball bearings with cylindrical and conical bore two kinds. Conical bore taper 1:1 2 or 1:30. In order to enhance the lubrication properties of the bearing outer ring on the processing tank, and three hole.
