Squishworx Carbon Fiber Rods are specially manufactured for 3D printer environment. Perfect match with Vesconite bushings.
Bearing noise will be gone and you will only hear the motors and fans. No lubing required so low maintenance is another benefit. But the best of all is the appreciable print surface quality due to smooth sliding on the axises.
Carbon Fiber rods are NOT suitable for ball bearings.
You can use Igus Drylin bushings or Vesconite Bushings and Carbon Fiber rods together.
Sold individually, you need 2 (two) for your Prusa MK Series Z-Axis.
16 grams per rod.
