The NA 4834 RICH is a needle roller bearing with an inner ring (170x215x45 mm) for high radial loads and use with unhardened shafts.
The NA 4834 RICH is a heavy-duty needle roller bearing with an inner ring, manufactured by RICH with robust metric dimensions of 170 x 215 x 45 mm.
Needle roller bearings are characterized by their very high radial load carrying capacity and their small cross-section. The inclusion of the inner ring in the NA 4834 RICH model simplifies mounting, as the bearing can be fitted onto a standard shaft without requiring the shaft surface to be hardened and ground to serve as a raceway. The precise guidance of the needle rollers is ensured by a robust steel cage, which provides stability and durability under demanding operating conditions. This design is exceptionally stiff and suitable for applications in heavy machinery, large gearboxes, and industrial equipment where high load support and compact installation are critical.
