ABSTRACT:
In a bearing arrangement for a rotary drum, the ends of two cradles are attached to load-carrying rollers which rotate freely over a surface area of a race of the rotary drum. The cradles run in self-aligning bearings in a load-bearing structure via intermediate cradles. Each load-carrying roller runs in bearings at the end of its respective cradle, in a manner which avoids slanting and which is free of axial clearance. Each cradle runs in rocker bearing located between its two load-carrying rollers, without bearing clearance at the end of an intermediate cradle. One of the intermediate cradles runs in a journal bearing with an axial clearance equal to or larger than the axial dislocation of the load-carrying rollers in the load bearing structure when the rotary drum is in operation.
