The NTN NATV series cam follower is a cylindrical roller bearing built around a solid stud, intended for cam and support positions where radial loads are heavy. Because the rollers run directly on cams or raceways, no separate cage is needed. Sealing is integrated into the bearing, which makes it a practical choice for transmission, guidance and actuation systems where load capacity matters and contamination is a concern.

Reading the code helps you order the right item. NATV identifies the cam follower family: cylindrical rollers, solid stud. The figure that follows is the outside diameter in millimeters, so NATV5LL/3AS is a roller with an outside diameter of 5 mm. LL tells you the bearing has contact seals on both sides, keeping contaminants out and lubricant in. The /3AS ending marks a particular construction variant within the series.

You will find these cam followers across many kinds of industrial equipment: machine tools, automation, conveyors, cam systems and linear guides. Food, textile, packaging and metalworking operations also use them, since the design packs high radial load capacity into a compact envelope and holds precision. The sealed version suits areas with dust, chips or moderate humidity.

When selecting an NATV cam follower, confirm the outside diameter, the overall width and the stud diameter you need. This series offers high radial load capacity and works well at moderate speeds. Choosing the LL seal is what carries service life in dirty environments. On mounting, check alignment and lubrication; many of these rollers arrive from the factory already greased and sealed, so no further maintenance is normally required.

On equivalences, NTN NATV series cam followers can be swapped for products from other makers that use the same nomenclature and dimensions. Check tolerances and seal type before substituting, because small differences can change how the bearing performs. If you want help identifying a replacement, send us the original part number and we will advise.
