The NTN KR series is a cam roller built as a roller bearing on an integrated stud, made to carry radial loads and transmit motion in cams, linear guides and lifting systems. Its construction and sealing suit industrial machinery where load capacity and protection from contamination matter. MR Industrial Accessories LLC supplies this series to customers in the United States and Latin America.
How to read the code: KR marks a cam roller with a stud. The digits that follow give the outside diameter in millimeters, so KR16 has a 16 mm outside diameter. FLL means a special double-lip seal that helps hold lubricant in and keep contaminants out. The /3AS ending is an NTN internal code for surface treatment or stud tolerance. Examples in this series include KR16FLL/3AS, KR19FLL/3AS, KR22FLL/3AS and KR26FLL/3AS.
These cam rollers appear in machine tools, packaging equipment, conveying systems, presses, cranes and lifting equipment, as well as on automotive assembly lines and in cam mechanisms for motion control. They handle high radial loads and resist contamination, so they work in areas with dust, chips or moisture when the correct seal is chosen.
When selecting a KR series cam roller, check the outside diameter you need, the seal type (FLL for double lip), the radial load and the operating environment. Align the roller precisely with the raceway during installation; too much misalignment shortens service life. Lubrication also matters: these rollers normally arrive pre-lubricated, but severe applications may call for relubrication. The FLL seal helps retain lubricant and block particles, though very aggressive conditions may require extra protection.
For equivalents, NTN KR series cam rollers can be interchanged with similar KR series from other brands, such as INA or SKF, provided the main dimensions and seal type match. Always confirm outside diameter, width, stud diameter and load capacity before replacing a unit. The safest way to find an exact equivalent is to send the complete part number of the original part along with the critical dimensions.
