It is certainly possible to extend bearing life by using cylindrical and/or tapered roller bearings in many pump models. Figures 3-63 and 3-64 illustrate this for bearings that can be used in the same bearing bracket. Note that this manufacturer uses the oil ring (Figure 3-61) only to maintain a uniform oil temperature throughout the entire sump.

Bearing rating life | SKF

For modern high-quality bearings, the calculated basic rating life can deviate significantly from the actual service life in a given appliion. Service life in a particular appliion depends not only on load and bearing size, but also on a variety of influencing factors including lubriion, degree of contamination, proper mounting and other environmental conditions.
