Strut profiles , slot 6, modular dimensions 20

Bosch Rexroth strut profiles with groove 6 grid 20 are extruded aluminum structural components designed for modular construction systems in industrial automation and workstation assembly. These profiles feature standardized groove geometry that accepts T-nuts and connectors for flexible frame construction. Primary applications include ESD-safe workstations, machine frames, conveyor supports, assembly fixtures, and protective enclosures in manufacturing environments. The 20mm grid spacing provides compatibility with standard automation components and allows precise positioning of accessories and mounting hardware across automotive, electronics, pharmaceutical, and general manufacturing industries.

Selection of Bosch Rexroth strut profiles depends on load requirements, span length, and structural stiffness needs with cross-sections ranging from 10x40mm to 20x60x40mm configurations. The 20x20mm profiles like part 3842517180 are suitable for light-duty applications up to 500N loads, while heavier 20x40x40mm profiles such as part 3842537818 support structural loads exceeding 2000N over 3000mm spans. Profile variants include single groove (1N), double groove (2N), triple groove (3N), and special configurations like 2NVS with varied slot positioning. Standard lengths of 1000mm and 3000mm accommodate most construction requirements, with moment of inertia values determining deflection characteristics under load.

Bosch Rexroth strut profiles comply with DIN EN 755-2 for aluminum extrusion tolerances and ISO 6891 for T-slot dimensions ensuring universal compatibility with standard fasteners and connectors. The aluminum alloy typically meets EN AW-6060 T66 specifications providing minimum yield strength of 160 MPa and ultimate tensile strength of 215 MPa. For ESD-sensitive environments, profiles can be anodized to meet IEC 61340-5-1 surface resistance requirements between 10^6 and 10^9 ohms. Machine safety applications require compliance with ISO 12100 for mechanical hazard reduction and EN ISO 13857 for safety distances when used in protective barriers or guard structures.

The 20x20mm profiles offer compact construction with groove depths of 6mm for light structural applications, while 20x40mm variants provide increased bending strength and torsional rigidity for medium-duty frameworks. Specialized configurations include D8/D8 profiles with 8mm diameter holes for pneumatic routing, 2NVS variants with asymmetric groove positioning for specific connector requirements, and reinforced 20x40x40mm triangular sections for maximum structural performance. Profile designations like 3N indicate three-sided groove accessibility, R designations specify rounded corners for improved handling safety, and VS suffixes denote special groove configurations for vibration-sensitive applications requiring enhanced damping characteristics.

Bosch Rexroth strut profiles require T-nuts sized for 6mm groove width with M6 or M8 threading depending on load requirements and corresponding socket head cap screws with 8.8 strength class minimum for structural connections. Profile ends must be cut square within 0.5mm tolerance using carbide-tipped saws to ensure proper joint alignment and load transfer. Corner connections utilize die-cast aluminum brackets or steel reinforced joints for 90-degree assemblies, while adjustable connectors accommodate angular requirements between 30 and 150 degrees. Pre-drilling is required for direct mounting applications with pilot holes sized 0.2mm smaller than fastener diameter to prevent aluminum thread stripping during assembly.

Bosch Rexroth strut profiles operate safely in industrial environments from -20°C to +80°C ambient temperature range with structural properties maintained throughout this spectrum. The extruded aluminum construction provides inherent corrosion resistance meeting ISO 9227 salt spray testing requirements for 500+ hour exposure without degradation. Load capacity derating begins at 60°C ambient temperature requiring 15% reduction in allowable stresses for elevated temperature applications. Surface treatments including anodizing achieve wear resistance values of 50+ HV hardness and can provide ESD-safe surface resistivity between 10^6 to 10^11 ohms per square when specified for electronics manufacturing environments requiring electrostatic discharge protection.

Bosch Rexroth strut profile systems require quarterly visual inspection for joint loosening, surface damage, and connection integrity with particular attention to high-vibration areas where fastener preload may decrease over time. Annual torque verification of critical structural joints should maintain M6 fasteners at 8-10 Nm and M8 connections at 18-22 Nm according to ISO 4762 specifications. Expected service life exceeds 20 years in normal industrial environments with proper installation and maintenance, while corrosive or high-temperature applications may require bi-annual inspection cycles. Profile surfaces should be cleaned with mild detergent solutions avoiding abrasive cleaners that could damage anodized coatings and compromise ESD properties in electronics manufacturing applications.
