Spherical Roller Bearing for Heavy Machiner

Description

Spherical roller bearings operate in arduous conditions. The spherical rollers can be symmetrical or unsym-metrical and are self-aligning in the outer ring sphered raceway. Thus, the possible coaxiality deviations of the supporting bearings as well as shaft bending can be compensated.

Spherical roller bearings are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling.

It have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions

Spherical roller bearings are designed with double-row raceway inner ring, spherical raceway outer ring and the convex symmetrical rollers. With the same center as the bearings, the spherically formed outer ring raceway can make self alignment, which can adapt the deflection between axis and housing bore.This kind of bearings can take great radial load, suitable for heavy machines used in paper-making, mining, vibration sieve, rolling mill and so on.

 Feaures:

•Excellent alignment compensation

•Suitable for large radial loads

•Low to medium speed ratings

Application :

heavy machinery (e.g. construction and mining machines), rolling mills, gear boxes, shaker screens, etc.
