NNTR Series

The NNTR Roller have an outer ring of great thickness necessary to guarantee the mechanical resistance suitable for limiting deformations under load to a minimum and withstanding shocks in the best possible way. The rounded external profile allows to compensate for possible misalignments present in the parts surrounding the bearing, to reduce the Hertzian contact pressure and therefore to guarantee less wear and a longer life of the counter track. The full complement of rollers execution allows these support rollers to withstand high loads, while keeping the overall dimensions reduced. The presence of integrated and grinded flanges in the outer ring allow these bearings to be used in applications where there is the presence of axial loads. They are mainly used on camshaft, as pressure rollers and as wheels in conveyors
