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
