✔️ Single Rail Pack Plus Dual Slider Set Meets Heavy Duty Needs

This handy linear slide unit set gives your machine steady tracking for heavy cuts. You will get one single rail pack and a dual block pack ready to mount. It handles dusty shop floors without jamming or slowing down your workflow.

✅ One 2900mm and 114 inch carbon steel rod covers long travel stretches smoothly
✅ Two 40mm and 1 point 57 inch open alloy slider blocks handle weight without wobbling
✅ Built in polymer guides replace loose steel balls to stop sudden drops completely
✅ Tight dust and waterproof rings keep sawdust out while you tackle rough cutting sessions

💡 Why pick sealed linear slide units for cnc router assemblies instead of traditional steel bearings?
Standard tracks trap grit and wear out fast on tough jobs. Here is how this setup keeps things running smooth.
- Open runner designs drain chips fast so your table never hits a snag during deep milling runs
- Polymer inner sleeves lower friction and keep motion quiet under constant axis acceleration
- Hard anodized alloy casings transfer motor heat away quickly and hold precise alignment all day
