XL Extrusions: A modular extrusion kit for the next generation of heavy payload cobots

August 23, 2023 | Quinn Harker

Ventionā€™s XL extrusions are the first modular extrusion kit specifically designed for the next generation of heavy-duty, 20-30 kg cobots. These 247.5 mm x 247.5 mm cross-section extrusions rank best-in-class in terms of structural rigidity, straightness, and precision with their double wall design.

The XL extrusions are indispensable for large structures that require reinforcement and bracing. See all the Vention Official designs that utilize XL extrusions, including an overheard 7th axis, a cartesian system, and more.Ā 


Our largest extrusions yet

When designing large structures using standard extrusions, manufacturers are forced to do heavy reinforcing and bracing, which often leads to longer assembly times and issues with alignment. To solve these issues, Vention has expanded its extrusion ecosystem to include 247.5 mm extrusions, our largest extrusion yet.Ā 

The XL extrusions effectively reduce the complexity and the number of parts used in heavy-duty structures. Although small extrusions remain a possibility for building these structures, they require heavy reinforcing and bracing, which leads to a longer, more complex assembly process.Ā 


High-level benefits of XL extrusions include:Ā 

  • Double wall design for extra rigidity
  • Half a metric ton of payload capacityĀ 
  • Floor anchoring plate with built-in levelling features
  • Smart assembly plates with leveling feature to ensure perfect alignment of top extrusion
  • Direct installation of peripherals such as actuators and controllersĀ Ā 
  • Simple and highly rigid structure designed with only a few parts

Calculating your machineā€™s strength

Before purchasing a heavy-duty application such as an overheard 7th axis or cartesian system, it is important to calculate your machineā€™s strength, rigidity, and friction joint capacity. To simplify these calculations, we have created a Deflection Calculator and a Joint Friction Calculator for you to use.Ā 


Deflection Calculator

Determining your machineā€™s strength and rigidity is easy with Ventionā€™s t-slot aluminum extrusion deflection calculator. Simply select your extrusion profile, load distribution, and applied forces to get instant results for stress, deflection, and safety factors.

Friction Joint CalculatorĀ 

Many joints made with extrusions rely on pure friction joints. Determine the load capacity of a joint fixed in place by pure friction by specifying the installation torque of the bolts and the number of fasteners in pure friction.
