Bearing fit is governed by the selection tolerances for bearing shaft diameters and housing bore diameters. Widely used fits for 0 Class tolerance bearings and various shaft and housing bore diameter tolerances are shown in Fig. 7.1. Generally-used, standard fits for most types of bearings and operating conditions are shown in Tables 7.2- 7.7.

As both bearing bore size and O.D. increase, their Normal tolerances increase as does the absolute tolerances for the shaft O.D.s and housing bores. Figure 2 is a graphic representation of the relationship to the various fits with the bearing bore and O.D. tolerances. Shaft fits represented above the bearing bore indicate an interference fit.

Machining tolerances The bearings are mounted on the shaft with adapter sleeves FAG H3260HGJ and FAG H3176HGJ, re-spectively. The bearing seats on the shaft are machined to h7 with a cylindricity tolerance IT5/2 (DIN ISO 1101), and the bores of housing and pitman to H7.

Roller Mils are directly driven bevel-wheel planetary gears or bevel cylindrical gear units. The gear unit represents an almost integral component of the mill. The output flange of the gear unit is rigidly connected with the grinding table. In addition to transmitting the torque,the gear unit also has capability to take up the reaction forces from the the griding force of the mils rollers.
