Abstract

A lubrication block, with or without a cavity, or a lubrication bag, for lubricating an ID surface of a tire and an OD surface of a plurality of pads of rotary trunnion supported equipment, such as a kiln, cooler, dryer, reactor, granulator and ball mill operating at temperatures from 100.degree. F. to 500.degree. F. or higher. The tire has inner and outer faces, and the inner face of the tire is slipped over the plurality of pads or filler bars welded to an outer shell of the rotary equipment.
