✅ Tough Gcr15 steel handles side pressure without bending the tracks
✅ Tight five millimeter bore clears cramped mounting spots easily

💡 Why pick sealed groove bearings for linear motion setups?
The V channel forces the balls into a fixed path to stop wandering during quick cycles.
- Dual metal covers trap the grease inside while blocking shop dirt completely.
- Hardened alloy rings grip the balls firmly to deliver dead smooth rolling motion.
