The NKE 22311EKC3W33 is a high-performance spherical roller bearing featuring an optimized internal design (E) for enhanced load capacity. It has a 55 mm bore diameter, a 120 mm outer diameter, and a 43 mm width. The 'K' designation indicates a 1:12 tapered bore, suitable for mounting with adapter or withdrawal sleeves. 'C3' specifies a radial internal clearance greater than normal, ideal for applications involving high temperatures or significant shaft deflection. The 'W33' feature denotes a lubrication groove and three lubrication holes in the outer ring, allowing for efficient relubrication. This NKE bearing is designed for demanding industrial applications requiring high reliability and performance.
