The Limberoller Troughing Idler consists of a steel wire rope that is completely encapsulated in rubber. The elastomer is molded to the rope, under heat and pressure, so that a virtually impervious sheath of rubber completely covers the rope. This basic design varies depending on belt width, by configuration of the molded rubber jacket. There are four series of Limberoller troughing idler assemblies 100, 150, 300 and 350. Troughing idlers consist of LR-100 and LR-150 Series troughing idlers with double row ball bearings and slotted to fit into a rigid mounting. LR-300 and LR-350 Series troughing idlers with tapered roller bearing in a trunnion type housing that fits into an oarlock type support. This design gives the idler freedom of motion in the direction of belt loading and travel. Troughing brackets feature steel standard, special and training troughing styles.
