Product Description
The NTN 22211K/W33 Spherical Roller Bearing is built for heavy-duty industrial applications requiring high load capacity, misalignment tolerance, and efficient lubrication. The “K” suffix indicates a tapered bore (1:12) for secure mounting on tapered shafts or with adapter sleeves, while the “W33” suffix denotes an annular lubrication groove with three lubrication holes in the outer ring, ensuring superior grease distribution and longer service life. Its double-row spherical roller design allows it to handle high radial loads and axial loads in both directions, even under vibration and shock conditions.
