Spherical roller bearings, thrust bearing load in a certain Angle SKF axis from a way to another roll. Spherical roller thrust bearing of another major characteristic is its ability to be adjustable, allows certain shaft bending and axial bearing and the error in between. Although it's basic properties and deep groove ball bearing should be similar, but because the bearing of rough mostly used in machinery, installation location is not very precise, axial and seat to neutral axis holes, or axial length and large deflection of the situation, but also not high precision bearings itself, and some structure is coarser, therefore the actual performance is common to the same specifications of deep groove ball bearings to play in discount. Therefore, in radial load bearing outside, still can withstand the role and axial load.
