Bosch Rexroth Strut Profiles

Strut profiles as the basis for machine building

Aluminum strut profiles are the core element of the Bosch Rexroth modular system. They are used to build machine frames, guarding enclosures, assembly workstations, frames and fixtures without welding or painting. The continuous slots accept connectors and accessories, so structures can be assembled quickly, extended and modified when needed. Low weight combined with high rigidity also makes the profiles suitable for moving assemblies.

Versions and selection criteria

• Cross-sections: from small profiles such as 22.5x45 and 30x30, through 45x45, 45x60 and 45x90, up to 60x60, 90x90 and 90x180.
• Light versions (L): such as 45x45L, 60x60L or 90x90L where lower weight matters more than maximum rigidity.
• Number of open slots: variants with one, two or three slots (1N, 2N, 2NVS, 3N) for smooth, closed outer faces.
• Slotted plates such as 22.5x180 as wide, flat elements.

Key factors are expected load, spans, connection method, slot size and appearance. Larger cross-sections offer higher rigidity, while light profiles save weight and cost.
