The NTN KR series cam roller is a roller bearing with an integrated stud, designed to withstand radial loads and transmit motion in cams, linear guides and lifting systems. Its robust construction and sealing make it suitable for demanding applications in industrial machinery, where high load capacity and resistance to contamination are required. MR Accesorios Industriales sells this series for the Argentine market.

The KR series designation is interpreted as follows: the letters KR identify a cam roller with a stud. The numbers that follow indicate the outside diameter in millimeters; for example, KR16 corresponds to an outside diameter of 16 mm. The FLL suffix indicates a special double-lip seal, which improves lubricant retention and contaminant exclusion. The /3AS ending refers to an NTN internal designation for the surface treatment or the stud tolerance. Thus, KR16FLL/3AS, KR19FLL/3AS, KR22FLL/3AS and KR26FLL/3AS are examples of this series in different sizes.

These cam rollers are used in a wide variety of industrial applications in Argentina: machine tools, packaging equipment, conveying systems, presses, cranes and lifting equipment. They are also found in the automotive industry, on assembly lines and in cam mechanisms for motion control. Their ability to withstand high radial loads and their resistance to contamination make them suitable for environments with dust, chips or moisture, provided the appropriate seal is selected.

To correctly select a KR series cam roller, take into account the required outside diameter, the type of seal (FLL for double lip), the radial load and the environmental conditions. Installation must ensure precise alignment with the raceway; excessive misalignment can reduce service life. Lubrication is critical: these rollers usually come pre-lubricated, but in severe applications relubrication may be necessary. The FLL seal helps maintain lubrication and exclude particles, although in very aggressive environments additional protection should be evaluated.

Regarding equivalents and interchangeability, NTN KR series cam rollers can be interchanged with products from other brands that follow similar designations, such as the INA or SKF KR series, as long as the main dimensions and the type of seal match. It is essential to verify the outside diameter, width, stud diameter and load capacity before replacing a unit. For an exact equivalent, the best approach is to provide the complete part number of the original part and the critical dimensions.
