FAG spherical roller bearings are double row , self-retaining units comprising solid outer rings with a concave raceway .

FAG Spherical roller bearings , 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 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 to 2.5 .There are two kinds of spherical roller bearings .One is cylindrical bore , the others is tapered bore .
