Product Description

The NTN 22318K/W33 Spherical Roller Bearing is engineered for heavy-duty industrial applications requiring high load capacity, secure shaft mounting, and efficient lubrication. The “K” suffix denotes a tapered bore (1:12), allowing precise and firm mounting on tapered shafts or adapter sleeves. The “W33” suffix indicates an annular lubrication groove with three lubrication holes in the outer ring, ensuring effective grease distribution, reduced heat generation, and extended bearing service life. Its double-row spherical roller construction provides excellent performance under very heavy radial loads and substantial axial loads in both directions. The self-aligning feature compensates for shaft deflection, angular misalignment, and installation inaccuracies, making it suitable for demanding industrial environments.
