Bearing 22312 W33 K NTN

Product Description

The NTN 22312K/W33 Spherical Roller Bearing is engineered for heavy-duty industrial applications where high load capacity, secure shaft mounting, and efficient lubrication are essential. The “K” suffix indicates a tapered bore (1:12), allowing for precise and firm installation on tapered shafts or adapter sleeves. The “W33” suffix denotes an annular lubrication groove with three lubrication holes in the outer ring, which ensures effective grease distribution, reduces operating temperatures, and extends 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 environments.
