Spherical roller bearing is in the two race between inner ring and groove for spherical outer ring, assembly cylindrical roller bearing.
Spherical roller bearings are divided into: cylindrical inner hole and cone inner hole. Cone inner hole of rear taper 1:12 respectively, codenamed K of spherical roller bearing type (153000 or 113000) and 1:30 rear codenamed K30 spherical roller bearing. This kind of bearing with conical shaft timing, inner ring moving along the axial radial clearance of the bearing can be adjusted.
Two columns of symmetrical spherical roller, there's a share of the spherical outer ring raceway, the inner ring has two the tilt Angle of a race to the bearing axis, has a good heart performance, when the axial stress bending or install different heart bearings can still be used normally, so vary with different bearing size series, generally allowed by the selfaligning Angle from 1 to 2.5 degrees, the type of bearing load capacity is larger, besides can bear radial load bearing can withstand the axial load, twoway role has good impact resistance, typically spherical roller bearing is allowed to work speed is low.
