The product may differ from the illustration
The 40x120L M12 strut profile is an asymmetric heavy-duty aluminum extrusion in the 40 mm modular grid, offering a high area moment of inertia of 203.2 cm⁴ in the x-direction for load-bearing frames, machine bases, and protective enclosures. All core bores are factory-prepared with M12 threads; D17 through-bores are provided in selected slots, enabling direct bolted connections without reworking. The anodized aluminum section is ESD-suitable and available cut-to-length from 60 mm to 6000 mm.

BRR-3842993140

The Bosch Rexroth strut profile 40x120L M12 is an asymmetric aluminum extrusion in the 40 mm system grid, designed for applications where high bending stiffness in the primary load direction is required - such as horizontal beams, cantilever arms, and base frames in assembly and automation systems. An area moment of inertia of 203.2 cm⁴ in the x-direction delivers substantially greater rigidity than a square profile of equivalent cross-sectional area. The profile is ESD-suitable, making it compatible with electrostatically sensitive production environments.

  • 8 open slots (slot width 10 mm) for flexible, drill-free connection and add-on mounting along the full profile length
  • M12 threaded bores in all core pulls - direct bolted connections, no tapping required on site
  • D17 through-bores in slots B/H, C/G, D/F and D17V in slots A/E - system-compatible connection options ex works
  • Anodized aluminum, natural color - corrosion-resistant, dimensionally stable, ESD-suitable
  • Cut-to-length from 60 mm to 6000 mm, supplied per piece at the cut-to-length price
