💡 What is an inner ring used for in needle roller bearings and linear slide units? An inner ring provides the hardened raceway and accurate bore so rollers run true and assemblies stay aligned. - Supports needle rollers and keeps smooth linear slide unit motion with low friction. - Creates a precise raceway for long wear life in sealed ball bearing or open needle roller applications. - Handy for retrofit or OEM assembly when pairing with corresponding rollers like RNA4905 and RNAF304017.
