FAQ

What is the required surface hardness for the shaft if not using this inner ring?

Typically, a shaft used as a direct raceway for needle rollers should be hardened to 58-64 HRC. Using this IR 140x155x35 inner ring eliminates the need for shaft hardening.

Is this inner ring pre-lubricated?

No, inner rings are typically supplied with a rust-preventive coating but are not pre-lubricated. The lubrication is provided by the system the bearing is installed in, along with the outer race and needle roller assembly.

Can this inner ring be used with bearing assemblies from other manufacturers?

Yes, this inner ring is manufactured to ISO standards and can generally be used with corresponding needle roller and cage assemblies from other manufacturers, provided the dimensional tolerances are compatible. Always verify the specific requirements of your application.
