FAQ

For this precision inner ring, a shaft tolerance of k5 or j5 is typically recommended to achieve the correct interference fit. Always consult the IKO engineering catalog for application-specific details.

The inner ring itself does not require lubrication, but it is a critical component of the overall bearing assembly which does. The lubrication (oil or grease) is determined by the needle roller bearing it is paired with and the application's speed, load, and temperature.

Yes, the IR series inner rings are designed to be used with shell-type needle roller bearings and machined needle roller bearings when the shaft cannot be used as a raceway. Ensure the inner ring width is appropriate for the outer bearing assembly.
