Find a combination of dimensions and lubricant parameters suitable for this conveyor application.

1.A hydrodynamically lubricated plain bearing is to be designed for a conveyor-roller support application in which the rotating cold-rolled steel shaft must be at least 100 mm nominal diameter and the bushing is to be made of poured babbitt, reamed to size. The radial bearing load is to be 18.7 kN. The desired ratio of length to diameter is 1.0. The shaft is to rotate continuously at a speed of 1000 rpm. Low friction drag is regarded as more important than high load-carrying capacity. Find a combination of dimensions and lubricant parameters suitable for this conveyor application.
