NNF 5048 ADA-2LSV 240x360x160 Bearing
Double Row Full Complement Cylindrical Roller Bearing
The NNF 5048 ADA-2LSV Double Row Full Complement Cylindrical Roller Bearings are designed to handle heavy radial loads and operate under tough conditions. These bearings feature two rows of cylindrical rollers, offering high load capacity and stiffness. They are sealed with two contact seals, ensuring protection from contaminants and reliable lubrication retention. Suitable for applications like gearboxes, rolling mills, and heavy machinery, the full complement design eliminates the need for a cage, optimizing load distribution across the rollers. This makes them ideal for slow-moving or oscillating machinery where high load support is essential.
