2. Mounting | NSK Global
Fitting with a press is widely used for small bearings. A mounting tool is placed on the inner ring as shown in Fig. 1 and the bearing is slowly pressed on the shaft with a press until the side of the inner ring rests against the shoulder of the shaft. The mounting tool must not be placed on the outer ring for press mounting, since

For indeterminate loads, it cannot be determined easily, but in most cases, both the inner and outer rings are mounted with an interference fit. Table 1 Rotating and stationary load of inner rings. Rotating load on inner ring. (1) When bearing load direction is constant, the inner ring rotates and the outer ring remains fixed.
