NNU 4940 Cylindrical Roller Bearing | FAG Double Row High Precision | 200x280x80 mm
The FAG NNU 4940 is a high-precision, double-row cylindrical roller bearing engineered for demanding industrial applications requiring exceptional rigidity and dynamic load capacity. Featuring a precision-machined brass cage and hardened steel rollers, this configuration ensures optimal roller alignment and reduced friction under heavy radial loads. The separable design, characteristic of the NNU series, simplifies installation and maintenance, allowing for independent mounting of the inner ring assembly and the outer ring. With robust construction and tight manufacturing tolerances, the NNU 4940 is ideally suited for environments where reliability and long service life are critical.
Designed primarily for use in critical rotating equipment such as high-speed machine tool spindles, large industrial gearboxes, rolling mills, and heavy-duty compressors, the NNU 4940 provides superior performance characteristics. Its substantial static and dynamic load ratings guarantee operational stability even in shock-loaded or heavily pre-loaded systems. By utilizing this FAG original component, industrial operators can achieve optimized machine uptime, minimal energy consumption due to reduced internal friction, and unparalleled operational security, making it a cost-effective solution for maximizing machinery investment.
