💡 What is an inner ring used for in a linear slide unit? An inner ring provides the precision raceway on shafts so balls roll smoothly and motion stays accurate. - Ensures consistent contact in sealed ball bearing and linear slide unit assemblies - Compatible with steel or ceramic balls in sealed bearing applications for improved wear life - Helps maintain preload, limit creep, and is handy for replacing worn raceways during service
