The NTN NATR series cam follower is a cylindrical roller bearing with a cylindrical outer surface, designed to withstand high radial loads in cam and support applications. Its robust construction and LL seal make it suitable for operation as a cam follower in disk cams, linear guides and lifting mechanisms. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.

The NATR series designation reads as follows: the letters NATR identify a cylindrical roller cam follower with a cylindrical outer surface. The number that follows indicates the outside diameter in millimeters; for example, NATR5LL/3AS has a 5 mm outside diameter, while NATR25LL/3AS reaches 25 mm. The LL suffix indicates that the roller incorporates contact seals on both sides, which retain the lubricant and block contaminants. The /3AS combination corresponds to an NTN internal designation that may indicate a steel cage, a surface treatment or a specific tolerance; to interpret it precisely, it is advisable to consult the NTN 2203/E catalog or write to us with the full part number.

In Argentine industry, NATR series cam followers are used in a wide variety of applications. They are found in machine tool cams, in guiding systems on packaging lines, in presses, in lifting equipment and in transmission mechanisms. They are also common in the food industry, where the LL seal helps maintain lubrication against frequent washdowns, and in the metallurgical sector, where radial loads are high. Their compact design allows them to be mounted directly on a shaft and act as a cam follower or support roller in reciprocating motion.

To correctly select an NATR cam follower, take into account the outside diameter you need, the type of load (predominantly radial), the rotational speed and the environmental conditions. The LL seal is suitable for environments with dust, moisture or liquid splashes; if the roller will be submerged or exposed to extreme temperatures, ask us about other seal variants. Mounting requires a shaft surface with the appropriate tolerance and careful alignment to avoid parasitic axial loads. The initial lubrication comes from the factory, but in severe applications relubrication through the provided hole may be necessary.

As for equivalents and interchangeability, cam followers from different brands may differ in dimensions, load capacity and type of seal. If you are replacing a roller from another brand, the safest approach is to compare the outside diameter, the overall width, the bore diameter and the type of seal. The NTN NATR series is a well-established reference, but not all brands use the same nomenclature. If you send us the part number of the original part or the dimensions, we will tell you the compatible alternative or quote the exact part number you need.
