💡 What is an inner ring used for in needle roller bearing assemblies and linear slide units? Short answer: it provides the hardened raceway for rollers and supports radial loads while keeping compact assemblies aligned. - Provides a precision raceway for needle rollers in compact bearing housings - Common in linear slide unit and transmission applications where space is limited - Works with shell-type needle roller bearings and can complement sealed ball bearing or ceramic setups for specific needs
