The NJ2311-E-M1A-C3 is an X-life type cylindrical roller bearing. X-life bearings provide better performance than normal cylindrical roller bearings due to a special internal construction. Contact surfaces, steel grade and rolling bodies are of a higher quality. X-life bearings combine a higher load capacity with a longer service life. The bearings generate less heat and allow for higher speeds. Finally, X-life bearings allow for longer maintenance intervals compared to normal cylindrical roller bearings.
E: Increased Load Capacity
M1: Solid Brass Cage, Two Piece, Roller Guided
