Product Description

Spherical roller bearing is in the two race between inner ring and groove for spherical outer ring, assembly cylindrical roller bearing. Roller, spherical roller bearing has two columns of major diameter under a load, at the same time can also carry axial load in either direction. Have high radial load capacity, especially suitable for overloading or under vibration loading work, but can't afford to pure axial load. This kind of bearing outer ring raceway is spherical shape, so the self-aligning performance is good, can compensate the alignment error. Self-aligning roller bearing type spherical roller bearing is divided into: cylindrical inner hole and cone inner hole.
