1. The bearing capacity of the rolling bearing is much smaller than that of the sliding bearing of the same volume; therefore, the radial dimension of the rolling bearing is large. Therefore, in the case of accepting a large load and the case where the radial dimension is small and the layout demand is compact (such as the crankshaft bearing of the internal combustion engine) ; use more sliding bearings,
2. The rolling bearing has large oscillation and noise; the uniqueness is especially obvious in the later stage of operation; therefore; the need for precision is high, and there is no possibility of oscillation; the rolling bearing is difficult to serve; usually the sliding bearing is better.
3. Rolling bearings are uniquely sensitive to foreign objects such as metal chips; once they enter foreign bodies in the bearing; they will have intermittent large oscillations and noise; they will also cause early damage. In addition, rolling bearings are prone to early damage due to metal clip impurities. Even if there is no early damage; the life of the rolling bearing has a certain limit. Therefore, the life of the rolling bearing is shorter than that of the sliding bearing.
