Linear bearing | BCN3D Sigma, Sigmax

Engineered for High-Performance Linear Motion

A high-precision miniature linear guide block designed to provide smooth, stable, and accurate movement for the BCN3D Sigma & Sigmax series, ensuring industrial-grade reliability in every print.

This linear bearing eliminates mechanical play and friction in the X and Y axes, allowing for the extreme positioning accuracy required for high-resolution 3D printing and complex geometries.

Key Features & Benefits

  • Miniature Gothic Arch Design: Absorbs loads from all directions (vertical and horizontal), ensuring high rigidity and long-term precision.

  • Industrial Durability: Manufactured from high-grade alloy steel to resist wear and maintain tight tolerances over thousands of hours of operation.

  • Frictionless Motion: Engineered with a recirculating ball system that minimizes resistance, enabling the high speeds characteristic of BCN3D printers.

  • Easy Maintenance: Features a compact design with integrated end-seals to prevent dust contamination and retain lubrication.

  • Seamless Integration: Fully compatible with the BCN3D Sigma rail system, allowing for a “drop-in” replacement that restores factory-spec performance.
