ABSTRACT:
This is a multirow bearing for supporting a work or back-up roll of a rolling mill. A seal case is fitted within the annulus between the inner races and outer races. The seal case is configured to fit entirely within the annulus. The seal cases have elastromeric portions which cooperate with an inner race to form barriers at the ends of the bearing.
The inner races may comprise a pair of inner races separated by a sealed spacer.
