💡 What is an inner race for needle roller bearings used for in linear slide units? An inner race provides the hardened running surface that needle rollers bear against, supporting shafts and enabling smooth linear motion. Quick overview: - Supports compact needle roller bearing assemblies in linear slide unit and shaft-mounted setups - Provides precise bore fit and hardened surface for long wear life and low friction - Helps maintain alignment in high-load, low-profile applications and can replace worn races in sealed ball bearing or linear guide systems
