💡 What is an inner ring used for with machined type needle roller bearings? It provides a hardened running surface when shaft hardening or finishing is impractical. - Provides a hard inner raceway so rollers run on a proper surface rather than wearing the shaft - Prevents premature shaft wear and pairs well with sealed ball bearing housings or linear slide unit installs - Eliminates additional shaft machining, handy for maintenance, rebuilds, and field service
