Features and benefits Large radial load capacity. Easy to install, it can be directly installed or installed on the cylindrical shaft by using an adapter sleeve or an assembly cylinder.
It can bear a certain axial load. The outer ring raceway of this type of bearing is spherical and can bear larger radial loads. Therefore, it has self-aligning performance and is not affected by the misalignment of the shaft and the bearing housing or the deformation and deflection of the shaft, and can compensate the coaxiality error.
There are two rows of spherical rollers, the outer ring has a common concave spherical raceway, the inner ring has two concave raceways inclined at an angle to the bearing axis, and the curvature center of the outer ring raceway is consistent with the bearing center.
In addition to bearing radial load, it can also bear bidirectional axial load and its combined load. The bearing capacity is large, and it has good anti-vibration and impact resistance.
Application Cylindrical roller bearings for generators, or single row angular contact ball bearings for high frequency motors. When selecting bearings
papermaking machinery,
various industrial reducers
reduction gears,
railway vehicle axles,
crushers
vibrating screens
printing machinery,
woodworking machinery,
