SKF bearing fitted to main axial load, its wide application. Although the thrust bearing installation is relatively simple, but the actual repair common errors still occur, the bearing ring and the ring installation incorrect result, bearing no longer, journal wear very quickly. Compression ring on the inner ring and shaft for transition fit, when the shaft driven compression ring and end-face friction and static parts, when axial forces, there will be resistance moment of friction torque is greater than the minor diameter fit, cause the compression ring and shaft forces turn the mating surfaces, increasing journal wear.
Therefore, SKF bearings installation should pay attention to the following several points.
(1) distinguish between the bearing ring and the ring (based on the inner diameter of the bearing size, diameter difference of 0.1~0.5mm).
(2) still distinguish between institutions (that is, not part of the movement, mainly refers to the Assembly).
(3) no matter what, loose ring of the bearing should always be in a stationary-side surface.
