Bearing 22318 W33 NTN

Product Description

The NTN 22318W33 Spherical Roller Bearing is designed for heavy-duty industrial applications requiring high load capacity, durability, and reliable lubrication. Its double-row spherical roller design allows it to carry very heavy radial loads and significant axial loads in both directions. The self-aligning feature enables compensation for angular misalignment, shaft deflection, and mounting inaccuracies, ensuring stable and smooth operation. The “W33” suffix indicates an annular lubrication groove with three lubrication holes in the outer ring, improving grease distribution, reducing friction, maintaining lower operating temperatures, and extending bearing service life. This bearing is commonly used in mining, cement, steel, and other heavy machinery industries.
