Linear Rail HGR30 100mm For CNC DIY Projects Premium Linear Guideway Rail Support For 30mm Slotted Bearings Rust Resistant Steel No Slider Included Extend Length By Ordering Multiples

High-Precision HGR30 100mm Linear Rail for CNC Builds
✔️ Rust-resistant steel rail supports 30mm slotted bearings, no slider

The HGR30 100mm linear rail is designed for CNC DIY projects, providing a smooth guiding surface for precision motion. It uses rust-resistant steel and features pre-drilled holes for easy mounting. The slider is not included, and you extend length by ordering multiples.

✅ Steel material: bearing steel used for linear bearings.
✅ Surface treatment: anti-rust finish enhances durability and hardness.
✅ Linear guiding system: smooth, precise motion with low friction.
✅ Mounting: steel support rail with pre-drilled holes for easy installation.
✅ Length extension: extend length by ordering multiples (200mm -> *2, 300mm -> *3, max *10).

💡 What is a CNC linear rail used for and how should you size it for a DIY project?

A properly sized rail keeps motion smooth and repeatable. - For compact builds, use 100mm length and extend with multiples as needed. - Align mounting holes with the frame for rigidity and accurate travel. - Use compatible 30mm slotted bearings with the rail for best results.✝️
