LMK6UU Square Flange Linear Ball Bearing Smooth As Butter Gliding Action Six Millimeter Inner Diameter And Twelve Millimeter Outer Diameter Heavy Duty Carbon Steel Four Row Design Pro Builder Choice For CNC Routers And 3D Printers Pair Of Two

Low friction slide bearings for cnc tools and 3d printer axes
✔️ six mm (.24 in) bore by twelve mm (.47 in) OD slide bearing pair

These square flange ball bearings provide consistent straight travel on cylindrical rods. You will find this pack of two working inside cnc router tables, 3d printer frames, and automated electronics where repeated sliding moves matter. The sealed side shields keep dust out while the pre lubricated rollers reduce drag during fast passes.

✅ Twelve mm (.47 inch) outer ring mounts securely on rods
✅ Six mm (.24 inch) inner hole aligns perfectly with guide shafts
✅ Nineteen mm (.75 inch) total length reaches deep mounting slots
✅ Carbon steel construction supports two hundred newton dynamic loads
✅ Dual sealed lips trap grease and keep abrasive dust off tracks

💡 What keeps linear slide units running trouble free on cnc equipment?
You get reliable axis tracking when you install components built around four row ball circuits. These mechanisms handle side loads without binding.
The tight clearance reduces play for cleaner cut lines
Sealed contacts trap lubrication while blocking shop dust
Heavy carbon steel housings resist warping under heat
Swapping them out stays handy when upgrading old tooling kits.
