Double row cylindrical roller bearings are designed for applications requiring high radial load capacity, excellent rigidity, and precise shaft guidance. Compared with single-row designs, the two-row roller arrangement provides greater load carrying capability and improved running accuracy.
Available in NN and NNU series configurations, these bearings are widely used in machine tool spindles, rolling mills, industrial gearboxes, electric motors, mining equipment, and other heavy-duty machinery. Optional tapered bore and W33 lubrication designs are available for demanding operating conditions.
Applications
- Machine Tool Spindles
- Rolling Mills
- Industrial Gearboxes
- Electric Motors & Generators
- Mining Equipment
- Cement Machinery
- Steel Processing Equipment
- Paper Machinery
