The NTN NATR series is a cylindrical roller cam follower with a cylindrical outer surface, built to handle high radial loads in cam and support positions. The LL seal makes it a practical choice for disk cams, linear guides and lifting mechanisms where lubricant retention and contaminant exclusion matter.

Reading the NATR code helps you confirm you are specifying the right roller. NATR identifies a cylindrical roller cam follower with a cylindrical outside surface. The number that follows is the outside diameter in millimeters: NATR5LL/3AS has a 5 mm outside diameter, and NATR25LL/3AS goes up to 25 mm. The LL suffix means contact seals are fitted on both sides, keeping grease in and dirt out. The /3AS segment is an NTN internal designation that can refer to a steel cage, a surface treatment or a specific tolerance. For a precise interpretation, check the NTN 2203/E catalog or send us the complete part number.

These cam followers show up in machine tool cams, packaging line guides, presses, lifting equipment and transmission mechanisms. The LL seal is useful in food processing, where washdowns are frequent, and in metalworking, where radial loads run high. The compact body mounts directly on a shaft and works as a cam follower or support roller in reciprocating motion.

When selecting an NATR cam follower, start with the outside diameter you need, then confirm the load is mainly radial, the rotational speed and the operating environment. The LL seal suits dusty, damp or splash-exposed areas; for submerged service or extreme temperatures, ask about other seal options. Mounting calls for a shaft surface with the correct tolerance and careful alignment to avoid parasitic axial loads. Factory lubrication is applied, but severe duty may require relubrication through the provided hole.

Cam followers from different brands can vary in dimensions, load capacity and seal type. If you are replacing a roller from another make, compare the outside diameter, overall width, bore diameter and seal type. The NTN NATR series is a well-known reference, but nomenclature is not universal. Send us the original part number or the dimensions and we will identify a compatible alternative or quote the exact part number you need.
