Strut profiles

Rectangular tube Bosch Rexroth

The Bosch Rexroth rectangular tube 50x50x2 mm extends the modular profile system with a closed hollow aluminium section. It is available as a cut-to-length item (3842992913, price per cut) and in pre-cut 1000 mm sections (3842992913-1000). Compared to open strut profiles, the rectangular tube presents a fully enclosed outer contour without visible slots, making it suitable for exposed cladding structures.

FAQ

Frequently asked questions about Rectangular tube Bosch Rexroth

What are square tubes and what are their primary industrial applications?

Square tubes (Vierkantrohre) are hollow structural profiles with equal width and height dimensions, primarily used in mechanical engineering for building frameworks, workstation systems, and assembly platforms. The Bosch Rexroth 50x50x2mm square tubes are commonly deployed in manufacturing environments for constructing ESD workbenches, conveyor supports, machine frames, and modular assembly systems. These profiles serve industries including automotive manufacturing, electronics assembly, pharmaceutical production, and general mechanical engineering where precise dimensional stability and structural integrity are essential.

What are the key technical selection criteria for industrial square tubes?

Square tube selection depends on cross-sectional dimensions, wall thickness, and length requirements for the specific load-bearing application. The Bosch Rexroth 3842992913 series features 50x50mm outer dimensions with 2mm wall thickness, providing optimal strength-to-weight ratio for medium-duty structural applications. Critical selection factors include moment of inertia for deflection calculations, material grade for corrosion resistance, and compatibility with standard connection systems. The 1000mm standard length option allows for efficient material utilization while custom cutting services accommodate specific project requirements.

Which standards and certifications apply to industrial square tube profiles?

Industrial square tubes must comply with DIN EN 10305 standards for cold-drawn welded steel tubes and ISO 12633 for dimensional tolerances of structural hollow sections. Bosch Rexroth profiles meet ISO 9001 quality management standards and adhere to European CE marking requirements for structural components. Material composition follows EN 10025 specifications for structural steels, while surface treatments comply with ISO 12944 corrosion protection standards. For specific applications, additional certifications may include ATEX compliance for explosive atmospheres and FDA approval for food industry applications.

What are the differences between standard length and custom-cut square tube variants?

The Bosch Rexroth 3842992913-1000 represents the standard 1000mm length variant with fixed dimensions, while the 3842992913 base model offers custom cutting services (Zuschnittpreis) for project-specific requirements. Standard lengths provide immediate availability and cost optimization for common applications, whereas custom cutting enables precise fitting for complex assemblies and reduces material waste. Both variants maintain identical 50x50x2mm cross-sectional specifications and material properties, with custom cutting typically involving additional processing time and per-meter pricing calculations based on the required finished length.

What installation requirements and connection methods apply to square tube systems?

Square tube installation requires compatible connection elements including corner brackets, T-joints, and end caps designed for the 50x50mm profile dimensions. Bosch Rexroth systems utilize standardized fastening methods with M8 or M10 bolted connections, ensuring reliable assembly without welding requirements. Installation demands precise cutting to length, deburring of cut edges, and proper alignment during assembly to maintain structural integrity. The modular design enables easy reconfiguration and expansion of existing systems, with connection points accommodating both rigid and adjustable joint configurations for various mechanical requirements.

What are the operating conditions and safety specifications for square tube profiles?

Industrial square tubes operate effectively within temperature ranges from -20°C to +80°C for standard applications, with material properties maintaining structural integrity across this spectrum. The steel construction provides inherent fire resistance meeting building code requirements, while the smooth surface finish reduces injury risk during handling and maintenance. Load ratings depend on span length and support configuration, with typical working loads ranging from 500N to 2000N for the 50x50x2mm profile under distributed loading conditions. Proper installation ensures compliance with workplace safety regulations and mechanical stability requirements.

What maintenance and inspection requirements apply to square tube structural systems?

Square tube systems require annual visual inspection for structural integrity, checking connection tightness, surface corrosion, and dimensional stability under operational loads. Preventive maintenance includes quarterly cleaning of surfaces to remove contaminants that could accelerate corrosion and semi-annual verification of joint torque specifications per manufacturer guidelines. Expected service life exceeds 20 years under normal industrial conditions when properly maintained, with replacement indicators including visible deformation, joint loosening, or surface corrosion exceeding 10% of wall thickness. Documentation of inspection results ensures compliance with industrial safety standards and facilitates predictive maintenance planning.
