Large 40120 C-Beam Extrusion

Introducing the Premium Large 40120 C-Beam Linear Rail Extrusion

Discover excellence with our top-tier aluminum C-track heavy-duty extrusion, meticulously engineered for the most demanding applications. This versatile profile is the ideal foundation for crafting larger CNC machines, large-format 3D printers, as well as plasma and laser cutting machines. Unlike traditional C-beam 4080 extrusions, which often suffer from excessive deflection when used in larger CNC machinery, our robust C-aluminum extrusion is here to redefine the standards.

Key Features:

  1. Tailored Accessories: We offer a comprehensive range of accessories designed exclusively for this aluminum guide rail profile, including gantry plates, end plates, nuts, and lead screws.
  2. Inspired by Excellence: Our C-section extrusion draws inspiration from the OpenBuilds original C-beam rails but stands out with its increased size, width, and weight, approximately twice the weight of a standard C-Beam.
  3. Enhanced Gantry Plate: Our gantry plate is sturdier (8mm thickness compared to the original 6mm) and more substantial (165x118mm compared to OpenBuilds’ 125x125mm Xlarge plate).
  4. Precision Engineering: The gantry plate can accommodate 8 “W” Delrin or Xtreme roller wheels, fastened to the plate with larger M6 bolts (as opposed to OpenBuilds’ M5 bolts), resulting in superior rigidity and reduced deflection. One side of the “W” wheels features eccentric spacers for precise wheel positioning and zero play.
  5. Versatile Design: Our gantry plates can also be used as double-sided plates to create a robust “closed-up” gantry system, crucial in CNC machinery environments prone to dust and milling chips. End plates are available upon request.
  6. Our Unique Design: This design is entirely our own, meticulously crafted, and manufactured in partnership with a reputable factory.

Included in this listing:

  • Large 40120 C-Beam extrusion guide rail
  • Gantry plate with Xtreme bearing rollers, featuring 8 wheels, each securely fastened with M6 stainless steel bolts. Four of these wheels include eccentric spacers for precision adjustment.
  • Extrusion end plates (pair) with end flange bearings suitable for 16mm diameter leadscrews.

Available Lengths:

For your convenience, we offer a range of lengths: 300mm, 500mm, 750mm, 1000mm, 1200mm, 1500mm, and 2000mm. If you require a longer rail, please reach out to us, and we’ll be delighted to assist.

Beyond CNC: The utility of our C-Track rail extends beyond the CNC industry. Construct lengthy sliding rails for various applications with our gantry plates’ impressive load tolerance. From heavy sliding doors to bespoke projects, our C-Track rail can handle it all.

Share Your Project: Simply share your project idea with us, and we’ll advise you on the suitability of our sliding rail. As an example of our capabilities, here’s a 3500mm long belt-driven actuator based on C-Track extrusion rail that we designed and made for one of our satisfied clients:
