FAQ

What does ‘without inner ring’ mean for the RNA3035 installation?

The RNA3035 is designed to run directly on a hardened and ground shaft. The shaft itself acts as the inner raceway. Ensure the shaft has a surface hardness of 58-64 HRC and a fine ground surface finish for optimal performance and lifespan.

What type of lubrication is recommended for this bearing?

This bearing is typically lubricated with grease or oil. The choice depends on the operating speed, temperature, and load. For most general applications, a high-quality lithium-based grease is suitable. For high-speed applications, oil lubrication via the groove and hole in the outer ring is recommended.

Can this RNA3035 bearing be used as a direct replacement for an INA RNA4906?

Yes, the Nadella RNA3035 and the INA RNA4906 share the same principal dimensions (35x45x16 mm) and are functionally interchangeable in most applications. However, always consult the machine’s technical manual to confirm that load ratings and speed limits of the replacement bearing meet or exceed the original specifications.
