Product Description
Spherical Roller Bearing.
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'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.
Chinese factory alibaba sale Low price spherical roller 22230 bearing 22230cc/w33 22230ca bearings with competitive quality
Application:
For mounting wherever axial and radial loads are expected
For most parts for torque transmission
Home appliances, electric motors, automotive components
Feature of Spherical Roller Bearing
1) The outer ring receway is the part of the spherical surface, and this type bearing has the internal self-aligning performance, to adapt the relative deviation of the shaft and hole.
2) It can bear the radial load and the impact load, also can bear a certain amount of two-way axial load.
3) Have same width as that of the traditional bearings, yet can carry heavy loads
4) Fit for two-way axial force and upsetting moment
5) Excellent quality (be compatible with leading brands)
6) Special treatment steel (can bear higher temperature)
