The SKF NNU4924BSPC3W33 is a high-precision double row cylindrical roller bearing designed for demanding applications. It features a tapered bore (120 mm) and a C3 radial internal clearance, allowing for axial displacement of the shaft relative to the housing. This bearing is part of the NNU 49 series, known for its high rigidity and load-carrying capacity. The 'B' suffix indicates a modified internal design, 'SP' denotes special precision (P5 tolerance class or better), 'C3' signifies a radial clearance greater than normal, and 'W33' indicates a lubrication groove and three lubrication holes in the outer ring. It has an outer diameter of 180 mm and a width of 46 mm, making it suitable for machinery requiring high rotational accuracy and stability.
