Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.The symmetrical barrel rollers freely align themselves to the concave outer ring raceway. As a result, shaft deflections and misalignments of the bearing seats are compensated.
Spherical roller bearing
can support so much radial load .It can also accommodate correct
axial load. Its outer ring raceway is spherical. So it owns the
aligning feature. It still works regularly, when the relative
incline angle between inner ring and outer ring is in the range of
1-2.5
