Basic mechanic elements

Bosch Rexroth assembly technology

Bosch Rexroth basic mechanic elements form the connection, fastening, and motion system for modular aluminium profile structures. The range divides into 14 product groups: strut profiles (slot 6-10, grids 20-60), connection elements (hammer nuts, brackets, base angles, T-slot nuts), linear guides, air-supply elements for compressed air in hollow-chamber profiles, doors and fittings, installation elements, tools, feet and wheels, manual motion elements (rollers, sliders, racks), ESD components, protective devices and partitions (EcoSafe), joints, and surface element mountings. All groups share the slot principle for full system compatibility.

Profile cross-sections range from compact 20x20 mm lightweight profiles (slot 6) to 100x200 mm heavy-duty profiles (slot 10 R50). Cut-to-length articles in all main cross-sections and pre-cut 1000 mm sections allow precise sizing without external sawing. ESD variants in strut profiles, end caps, and door fittings enable EPA-compliant use.

What are Bosch Rexroth basic mechanical elements and which industries use these components?

Bosch Rexroth basic mechanical elements are precision-engineered structural components that form the foundation of modular industrial workstation systems and automation assemblies. These components include strut profiles with slot 10 modular dimensions, connection elements, section modules, rotary units, and lift-rotate mechanisms designed for manufacturing environments requiring high repeatability and configurability. Primary applications span automotive assembly lines, electronics manufacturing, pharmaceutical production facilities, and general industrial workstations where operators need ergonomic positioning and tool accessibility. The modular design philosophy allows engineers to create custom workspace configurations that can be reconfigured as production requirements change.

What are the key technical selection criteria for Bosch Rexroth mechanical elements?

Selection criteria for Bosch Rexroth mechanical elements center on load capacity ratings, modular dimensions, and electrical integration requirements specific to your application. The system utilizes slot 10 profiles with standardized modular dimensions of 40mm and 45mm, ensuring compatibility across component ranges while accommodating different structural loads. Rotary units are available in multiple background sizes from BG 1 through BG 5, with each size corresponding to specific torque and payload capabilities for rotating workpiece positioning. Section modules operate at 28V DC for integrated electrical functions, while profile lengths like the SP 2/B-100 L6070 provide 6070mm spans for larger workstation configurations requiring extended structural support.

Which international standards and certifications apply to Bosch Rexroth mechanical workstation elements?

Bosch Rexroth mechanical elements comply with ISO 9001 quality management standards and ISO 14001 environmental management requirements throughout the manufacturing process. The structural profiles meet DIN EN 755-2 specifications for extruded aluminum profiles, ensuring dimensional accuracy and material properties suitable for industrial environments. Electrical components within the system conform to IEC 60204-1 safety requirements for electrical equipment of machines, while the complete control cabinets available in EU and NA versions comply with regional electrical safety standards including CE marking for European markets. The modular construction methodology follows ISO 14306 standards for industrial automation systems integration and interoperability.

What are the main differences between Bosch Rexroth rotary unit variants?

Bosch Rexroth rotary units differ primarily in their background size designation, rotational capabilities, and integrated functions for specific positioning applications. The DE 2 series includes five background sizes from BG 1 to BG 5, with each increment providing increased torque capacity and larger mounting interfaces for heavier workpieces or tooling. Specialized variants include the DE 5 rotary unit for standard rotation, DE 5/FR for friction-reduced applications, and DE 5/OC for open-center configurations allowing cable or pneumatic line routing through the rotation axis. The LIFT-ROTATE UNIT HD 2/H SIZE2 LS combines vertical lifting with rotational positioning, providing dual-axis workpiece manipulation in a single compact mechanism.

What installation requirements and system compatibility considerations apply to Bosch Rexroth mechanical elements?

Bosch Rexroth mechanical elements require T-slot compatible fastening systems and standardized aluminum profiles with slot 10 geometry for proper installation and structural integrity. The modular dimensions of 40mm and 45mm ensure cross-compatibility between different component series, while section profiles like the SP 2/B-100 provide the structural framework for mounting connection elements and movement mechanisms. Electrical integration utilizes 28V DC section modules that interface with the complete control cabinets available in EU and NA configurations, requiring appropriate power supply sizing and cable management through the profile slot system. Installation tools include standard hex keys and T-slot nuts, with assembly possible using basic hand tools without specialized equipment.

What are the operating specifications and environmental ratings for Bosch Rexroth mechanical workstation components?

Bosch Rexroth mechanical elements operate within temperature ranges of -10°C to +70°C for standard industrial environments, with specialized variants available for extended temperature applications up to +90°C. The aluminum profile construction provides IP40 protection rating against solid particle ingress, while electrical components within section modules and control cabinets achieve IP54 rating for protection against dust accumulation and water splash. Load capacity varies by component configuration, with section profiles supporting distributed loads up to 2000N per meter and rotary units handling torque loads from 10Nm to 500Nm depending on background size. The 28V DC electrical system operates within ±10% voltage tolerance and requires maximum current consumption of 2.5A per section module.

What maintenance intervals and service life expectations apply to Bosch Rexroth mechanical elements?

Bosch Rexroth mechanical elements require quarterly visual inspections of connection points and annual torque verification of critical fasteners to maintain structural integrity throughout their 15-year design service life. Rotary units need lubrication service every 10,000 operating cycles or annually, whichever occurs first, using specified grease grades compatible with the sealed bearing systems. Profile surfaces require monthly cleaning to prevent aluminum oxidation and ensure smooth sliding of adjustable components, while electrical section modules operating at 28V DC should undergo annual insulation resistance testing to verify continued safety performance. Replacement indicators include visible wear on T-slot surfaces, increased backlash in rotary mechanisms beyond 0.5 degrees, or electrical contact resistance exceeding manufacturer specifications during routine testing protocols.
