NNU 4164 F

The NNU 4164 F Double Row Cylindrical Roller Bearing is an exceptional choice for industrial applications requiring outstanding radial load capacity combined with the ability to operate at high speeds. With a significant 320mm bore diameter, 540mm outer diameter, and 218mm width, this robust bearing features two rows of precision-engineered cylindrical rollers. Its "NNU" design denotes an outer ring with three integral flanges and an inner ring without flanges, allowing for essential axial displacement in both directions relative to the shaft.

This separable design greatly simplifies mounting and dismounting, enabling easier maintenance and component interchangeability, which translates to reduced downtime in critical machinery. Engineered from advanced materials and utilizing precise manufacturing techniques, the NNU 4164 F minimizes friction and heat generation, contributing to an extended service life even under demanding conditions. It delivers superior stability and rigidity, preventing unwanted twisting or bending in applications that demand high accuracy. Common applications include precision machinery, heavy industrial gearboxes, wind turbines, aerospace components, high-performance automotive systems, and other equipment where high radial loads, rotational precision, and reliable performance are paramount.
