Product Description

The NTN 22311K/W33 Spherical Roller Bearing is designed for heavy-duty industrial applications where high load capacity, secure shaft mounting, and reliable lubrication are essential. 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 efficient grease flow, reduced heat generation, and extended service life. Its double-row spherical roller design provides excellent performance under very heavy radial loads and significant 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.
