Abstract
An oil film bearing for rotatably supporting the journal surface of a rolling mill roll neck on a hydrodynamically maintained oil film. The bearing includes a bushing having outlets adapted to axially interrupt the load carrying continuity of the oil film by draining oil from the load zone at locations intermediate to the ends of the bushing, thereby subdividing the load zone into at least two axially separated pressure zones. Position sensors are located between the pressure zones to monitor the spatial relationship or oil film thickness between the bushing and the journal surface. The journal surface is defined by at least two sleeve segments received on and fixed relative to the roll neck. Adjacent ends of the sleeve segments are aligned radially or in a coplanar relationship with the axial separation between the pressure zones. Temperature sensors monitor the temperature of the oil being drained through the aforesaid outlets.
