NUTR-series support rollers from INA are cylindrical roller bearings built with a thick-walled outer ring. They are made to carry high radial loads along with moderate axial forces while rolling, and they often serve as cam or support rollers in guides, cams and conveying systems where the outer ring itself acts as the running surface.

Reading the part number is straightforward: NUTR is the series prefix, and the digits that follow give the roller's outside diameter. That is why NUTR15, NUTR17, NUTR20, NUTR25, NUTR30, NUTR35, NUTR40 and NUTR45 step up in size, with the larger numbers generally offering higher load capacity. In these references there is no extra suffix; the base number already describes a support roller with a thick outer ring and no outer needle cage, ready to roll directly on a raceway.

Typical applications include linear guides, machine tool carriages, cam systems, chain conveyors, presses, packaging machines and handling equipment. The design allows a solid bushing or plain roller to be replaced by a unit with an integrated bearing, which reduces wear and sharpens motion accuracy.

When selecting a NUTR roller, match the outside diameter and overall width to your application, then confirm whether the load is mostly radial or combined with moderate axial force. Check that the raceway has adequate hardness and a good finish; a soft raceway may be marked by the roller. Mount it on the correct shaft or pin and keep alignment accurate to avoid side loads. Depending on the application, lubrication may be permanent or relubricable, and the seal keeps dust and contaminants out.

INA NUTR support rollers may have dimensional counterparts from other manufacturers using similar nomenclature, but cross-brand interchange is not automatic because tolerances, capacities and suffixes differ. When replacing an existing roller, compare the main dimensions and operating loads. If anything is unclear, send the part number stamped on the roller or the housing dimensions and we will help identify the right option in the INA line.
