Strut profiles

Basic mechanic elements

Bosch Rexroth strut profiles form the load-bearing structure of modular workstation systems, machine guards, and transfer lines. The range is organized by slot size and modular dimension: slot 6 with 20 mm grid (profiles 20x20 to 20x60), slot 8 with 30 mm grid (profiles 30x30 to 60x60), slot 10 with grids of 40, 45, 50, and 60 mm (profiles 40x40 to 100x200), plus special profiles such as rectangular tubes, frame, angle, clamping, and cover profiles. All profiles are anodized aluminium and are supplied in standard lengths up to 6070 mm or cut to length.

Complementing the base profiles: end caps, cover profiles in PVC and aluminium (slots 6, 8, 10, multiple colours), profile rails for trolleys, and rubber profiles as foot pads. Full system compatibility within each slot size enables configurable frame construction without custom parts.

Standard lengths reach up to 5600 mm or 6070 mm depending on the profile series. Cut-to-length articles (order numbers with "Zuschnittpreis" suffix) allow millimetre-precise sizing, with 1000 mm sections also available as individual items. Profile rail 30x45C is stocked in 5600 mm, 6070 mm, and 6170 mm as well as cut to length. Rubber foot pads (10N) are similarly offered both in bulk metre form and cut to 1000 mm.

Typical applications: Building modular workstation systems and assembly frames in electronics and automotive manufacturing, constructing machine guards and safety fences, integrating conveyor frames and transfer lines (TS 2plus, VarioFlow+), and setting up laboratory equipment, storage systems, and cleanroom frames. The consistent slot principle allows later extensions without redesign.

What are Bosch Rexroth strut profiles and which industries use them for mechanical assemblies?

Bosch Rexroth strut profiles are precision-engineered aluminum extrusion systems designed for modular mechanical construction in industrial workstation and automation applications. These profiles feature standardized T-slot groove systems that enable rapid assembly of frames, conveyor supports, machine guards, and ESD workstations across automotive manufacturing, electronics assembly, packaging machinery, and laboratory environments. The profile system supports loads from light-duty 30x90mm configurations to heavy-duty 100x200mm structural members, with groove widths of 8mm, 10mm, and 20mm accommodating various fastening accessories and connection elements.

How do I select the correct Bosch Rexroth profile dimensions based on load requirements and span length?

Profile selection depends on the section modulus required for your specific load and span combination, with cross-sectional dimensions ranging from 30x90mm for light applications to 100x200mm for structural loads exceeding 500kg. The groove spacing designation follows the format 'slot width x profile length', where standard lengths include 5600mm and 6070mm with custom cutting available. For typical workstation applications, 60x60mm profiles with 20mm grooves handle distributed loads up to 200kg per meter, while 90x90mm profiles with 6mm grooves support concentrated loads exceeding 300kg at mid-span without deflection beyond ISO tolerance limits.

Which international standards govern Bosch Rexroth profile manufacturing and assembly tolerances?

Bosch Rexroth profiles comply with DIN EN 755-9 for aluminum extrusion dimensional tolerances and ISO 9001 quality management standards for consistent manufacturing processes. The T-slot groove geometry adheres to DIN 508 specifications for standardized fastener compatibility, ensuring interchangeability with certified connection elements and accessories. Profile straightness maintains tolerances within 0.5mm per meter length according to EN 12020-2, while surface finish meets Ra 1.6 requirements for smooth sliding applications and proper seal integration in pneumatic and hydraulic system mounting applications.

What are the main differences between R40 and R45 series Bosch Rexroth profile variants?

The R40 series features standard rectangular cross-sections with parallel groove orientation optimized for linear bearing applications and belt conveyor mounting, while R45 series profiles incorporate angular groove configurations at 45-degree orientations for enhanced torsional rigidity. R40 profiles like the 60x60 20x6070mm variant provide maximum accessibility for T-slot nuts and fasteners, whereas R45 profiles such as the 45x90x90L series offer superior moment resistance for cantilever loading conditions. The groove depth varies between series, with R40 maintaining 11mm depth for standard fasteners and R45 providing 8.2mm depth for specialized angular connectors and pivot joints.

What connection methods and accessories are required for Bosch Rexroth profile installation?

Bosch Rexroth profiles utilize T-slot nuts, end fasteners, and angular connectors that slide into the groove system before final positioning and tightening to specified torque values between 8-25 Nm depending on fastener size. The modular design accommodates both rigid connections using corner brackets with M8 or M10 bolts, and adjustable joints using pivot connectors for applications requiring angular positioning or thermal expansion compensation. Profile cutting requires carbide-tipped saws with 120-tooth blades operating at 3000 rpm to maintain groove integrity and prevent aluminum burr formation that could interfere with accessory installation and sealing performance.

What are the operating temperature limits and environmental ratings for Bosch Rexroth aluminum profiles?

Bosch Rexroth aluminum profiles maintain structural integrity across operating temperatures from -40°C to +80°C with minimal thermal expansion of 23 x 10⁻⁶ per Kelvin, making them suitable for both refrigerated environments and moderate heating applications. The anodized surface treatment provides Type II anodizing per MIL-A-8625 with 12-25 micron coating thickness for corrosion resistance equivalent to IP54 environmental protection when properly sealed. Load-bearing capacity remains constant within the temperature range, though thermal cycling above 60°C may require expansion joints every 6 meters to prevent stress concentration at fixed connection points in large structural assemblies.

What maintenance intervals and inspection procedures are recommended for Bosch Rexroth profile assemblies?

Bosch Rexroth profile assemblies require annual inspection of connection torque values and groove condition, with retightening of fasteners to original specifications if loosening exceeds 10% of initial torque measurement. The anodized surface should be cleaned quarterly using mild alkaline detergent to remove industrial contamination that could accelerate corrosion, particularly in environments exceeding 70% relative humidity. Critical load-bearing joints require semi-annual verification of straightness within 0.5mm per meter tolerance, while T-slot grooves need periodic clearing of debris accumulation that could prevent proper fastener engagement and compromise structural integrity over the typical 20-year service life.
