💡 What is an inner ring used for in roller bearing assemblies? An inner ring provides the raceway and ensures correct roller alignment for a rotating shaft. Quick intro sentence: - Provides a hardened raceway for needle roller and sealed ball bearing setups - Helps control shaft fit, preload, and smooth rotation in linear slide unit and transmission parts - Works with tapered bores and housings to simplify installation and extend bearing life
