The spherical roller thrust bearings are basically smilar to the thrust ball bearings in structure with only differences concerning the rolling body and raceway, our factory produces spherical roller thrust bearings, cylindrical roller thrust bearings and taper roller thrust bearings.
The spherical roller thrust bearings are separate type of bearings, which can carry axial and radial loads. But the radial loads can't exceed 55% of the axial loads. The bearings owns the property of self-aligning, allowing the aligning angle to be 1.5'~2.5' acc. To the difference in the series of bearings diameters and allowing the aligning angle to derease as the bearing loads increase.
Cylindrical roller thrust bearings(type 9000)and taper roller thrust bearings(type 19000)are separate type of bearings, which can be mounted with shaft rings, seat rings and cages sparately. The inclined axiss of shaft to housings is not allowed during mounting.
The bearing is only applicable for low speed rotation and can only carry axial loads with out restriction of the radial displacement of the shaft.
In order to prevent the occurrence of relative sliding of sollers to race way caused by centrifugal during the operation of the bearings, leading to the separation of shaft and seat rings, a certain minimum amount of axial loads must be applied to the bearings.
