Bearing 22317 W33 NTN

Product Description

The NTN 22317W33 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 withstand very heavy radial loads and significant axial loads in both directions. The self-aligning feature compensates for angular misalignment, shaft deflection, and mounting inaccuracies, ensuring smooth and stable operation. The “W33” suffix indicates an annular lubrication groove with three lubrication holes in the outer ring, enhancing grease circulation, reducing friction, maintaining lower operating temperatures, and extending bearing service life. It is widely used in mining, cement, steel, and other heavy machinery industries.
