The raceways in the outer ring of this type bearing are designed with a spherical surface whose center coincides with the bearing centerline.The bearings are of an improved design which incorporates a modified line contact between the raceways and rollers.This construction allows the bearing to have a very heavy radial load.In addition to its excellent radial capacity,this bearing can also accept a relatively large amount of bidirectional axial loading.Spherical roller bearings can also accommodate some angular misalignment,which makes them excellent choices where shaft deflection or housing alignment is existing.
