Abstract
A roller assembly having modular replaceable and interchangeable components for use in agricultural machines having endless conveyors with edges which pass over or under roller assemblies. The roller assembly has a long wearing resilient outer tire which is secured to a hub assembly. The hub assembly is comprised of two hub members having central bores forming a cavity within which resides bearings. The bearings are selectively sealed with a resilient washer element. A spacer on each respective end of the roller assembly is optionally added to accommodate mounting to a machine frame and for repair. An optional flange attaches on one side of the roller to help align the conveyor. The modular components may be packaged to provide a kit of parts usable for modular assembly, repair, or replacement purposes.
