Basic introduction to spherical roller bearing

The core roller bearing has two rows of rollers, mainly bearing radial load, but also bearing axial load in either direction.It has high radial load capacity, especially suitable for working under heavy load or vibration load, but can't bear pure axial load.The raceway of the outer ring of this kind of bearing is spherical, so it has good centering performance and can compensate the coaxial error.

Has two columns symmetric spherical roller type, 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 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.

spherical roller bearing

Self-aligning roller bearing press roller cross section shape is divided into symmetric form spherical roller and asymmetric form spherical roller two kinds of different structure, asymmetric spherical roller bearings belong to the early products, primarily for the host service at present, the new design when the host is rarely choose symmetric spherical roller bearing, the internal structure after comprehensive improvement design and parameter optimization, compared with the early production of spherical roller bearings, able to bear a greater axial load, the bearing operating temperature is low, so it can adapt to the requirement of high speed.According to with or without inner ring guard and retainers used different can be divided into two kinds of, C model and CA model, the characteristics of C type bearing inner ring is no guard and USES the steel plate stamping cage, the CA model.
