spherical roller bearings

Description

Spherical roller bearing has two columns of roller, mainly bear radial load, but also can 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. Has two columns symmetric spherical roller type, there is a share of the spherical raceway outer ring, inner ring has two tilted to the bearing axis Angle of the race, 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 self-aligning 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, two-way role has good shock resistance, typically spherical roller bearing is allowed to work speed is low.
