Checking spherical roller bearings
Before fitting the bearing, the internal radial clearance above the roller located in the highest position must
be checked with a feeler gauge (see Fig. 8-1 Checking radial clearance on bearings).
During fitting, check the reduction of internal clearance beneath the lowest roller several times.
Correct fitting is obtained with a reduction of internal clearance and minimum residual clearance
corresponding to the indications given in Chart 8-3 Checking radial clearance on bearings
