💡 Why are case hardened chrome linear shafts used in linear bearing systems?
Case hardened chrome shafts are made to deliver smooth travel while resisting wear under constant motion.

• Hardened outer layer reduces friction and wear from linear bearings

• Chrome plating improves surface smoothness and corrosion resistance

• Maintains accuracy and straightness during repeated sliding cycles

• Ideal for linear guides in CNC, printers, and automated equipment

A handy choice when you need strong, smooth, and reliable linear shafting for precision motion and bearing-guided setups.
