Mounting

SKF strongly recommends the use of backing bearings belonging to the same cross-sectional height group (table 1) on any one support shaft. After removing the transport locking devices, backing bearings and support saddles should be pushed alternately onto the shaft using suitable mounting equipment. During mounting, care must be taken that, for example, the inner ring of cylindrical roller backing bearings is not pushed out of the roller complement as this will cause the rollers of full complement bearings to fall out of the bearing.
To avoid a negative effect of the wall thickness variation of the inner rings on the quality of the rolled material, all inner rings on a support shaft should be turned so that the arrows indicating the position of the maximum wall thickness all point in the same direction (fig. 1).
