Spherical roller bearings

Key Attributes.

Spherical roller bearing have two raceways on inner ring, spherical raceway on outer ring and spherical rollers. Since the center of the arc raceway on the outer ring is the same as the center of the whole bearing arrangement, so these bearings are self-aligned and automatically adjust the eccentricity arose from the error of mounting bearings or from the bending of the shafts. The bearings can normally run when the acute angle between the centric lines of outer ring and inner ring ranges within 1°-2.5°.The bearing can accommodate radial load and axial load in double directions. The especial radial load carrying capability makes bearings suitable for heavy load and shock load carrying. These bearings have forms of cylindrical bore and tapered bore. The tapered bore bearings are fixed on the shafts by adapter sleeves or withdrawal sleeves, the mounting and dismounting are quite convenient. Applications of these bearings are found in metallurgy, mining, heavy-load machines, oil, chemistry, papermaking and construction and construction industries etc.
