INA RNA NA 6905 Needle Bearing 30x42x30 mm RNA-NA -6905

The INA RNA/NA 6905 is a high-performance needle bearing developed for high radial loads and compact installation conditions. With its needle-shaped rolling elements, it offers high load capacity in a minimal space, making it ideal for heavily loaded, dynamic applications. The bearing has a design without an inner ring (RNA) or can be used with an inner ring (NA), providing flexible mounting options. Made of high-quality bearing steel, it ensures excellent wear resistance, dimensional accuracy, and a long service life - even at high speeds and demanding operating conditions. Typical applications are gearboxes, machine tools, automation systems, textile machines, and various drive and lifting systems. The robust design ensures smooth, efficient operation and reliable performance in continuous operation.
