The roller path of the outer ring is spherical and self-aligning , which can compensate for the tolerance caused by different concentricity and rotor eccentricity monitor. However, the comparative angularity of its inner and outer rings can not exceed 3°.

    1. The roller path of outer ring is part of the spherical surface, bearing has the inner self-aligning performance, so that it can adapt to the relative deflection between shaft and pillow block bore.

2. It can undertake radial heavy load and pressing load, also can undertake double-direction axial load.

3. This kind of bearing can restrict the shaft or housings axial displacement in the range of bearings axial windage.

4. The structure principle and characteristic of this bearing is the same with self-aligning bearing, with the permission of the load capacity and limiting speed, they can be inter-changed.

5. The taper pore bearing is convenient for the shafts fold and pack by using fasteners and withdraw.
