Chain conveyor system VarioFlow plus

VarioFlow plus stainless steel system

The Bosch Rexroth VarioFlow plus stainless steel system provides horizontal curves in stainless steel (STS) for all three chain widths 65+, 90+ and 120+. Curves are available in three angles (30°, 45°, 90°) and two curve radii (R500 and R700), enabling flexible track topologies in hygienic and cleanroom-compatible manufacturing environments. The cylindrical carrier profile in stainless steel tube (48.3x1.5 mm) combined with connectors (cross-connector VG-311) and foot variants (Bipod, Tripod, Bipod with flange) forms the support structure.

FAQ

Frequently asked questions about VarioFlow plus stainless steel system

What is the Bosch Rexroth VarioFlow plus stainless steel system and what industrial applications does it serve?

The Bosch Rexroth VarioFlow plus stainless steel system is a modular chain conveyor platform designed for demanding industrial environments requiring corrosion resistance and hygienic material handling. The system primarily serves pharmaceutical manufacturing, food processing, chemical plants, and cleanroom assembly operations where stainless steel construction meets strict contamination control requirements. Available in conveyor widths of 65mm, 90mm, 120mm, 160mm, 240mm, and 320mm, the system accommodates diverse payload capacities and facility layouts. The modular design enables rapid reconfiguration of production lines while maintaining operational flexibility across multiple manufacturing sectors.

What are the key technical selection criteria for VarioFlow plus stainless steel conveyor curves and drive holders?

Technical selection for VarioFlow plus stainless steel components centers on conveyor width matching existing system dimensions, curve radius selection, and deflection angle requirements. Available curve options include 65mm, 90mm, and 120mm widths with radius specifications of R500 and R700, accommodating deflection angles of 30°, 45°, and 90° for precise path routing. Drive holder assemblies span widths from VF120+ to VF320+ with integrated mounting provisions for motor interfaces. The stainless steel construction provides enhanced chemical resistance compared to standard aluminum profiles while maintaining the same modular connection standards. Selection requires matching conveyor width, required turning radius, and total deflection angle to optimize material flow efficiency.

Which international standards and certifications apply to Bosch Rexroth VarioFlow plus stainless steel conveyor systems?

Bosch Rexroth VarioFlow plus stainless steel systems comply with EN ISO 12100 machinery safety standards and EN 1398 conveyor safety requirements for industrial material handling equipment. The stainless steel construction meets DIN EN 10088 specifications for corrosion-resistant steel grades, ensuring compatibility with food contact applications under EU Regulation 1935/2004. Electrical components integrate according to IEC 60204-1 safety standards for electrical equipment of machines, while mechanical assemblies conform to ISO 4762 specifications for socket head cap screws and fastening systems. Systems designed for potentially explosive atmospheres can incorporate ATEX-certified components meeting EN 60079 standards when specified during configuration.

What are the main differences between VarioFlow plus stainless steel curve variants and drive holder configurations?

VarioFlow plus stainless steel curves differentiate primarily by conveyor width designation (65+, 90+, 120+), turning radius (R500 for compact installations, R700 for higher speeds), and deflection angles of 30°, 45°, and 90° for various layout requirements. The 65mm width curves like part 3842557051 handle lighter payloads in confined spaces, while 120mm variants such as 3842557061 accommodate heavier products with greater stability. Drive holder sets including VF120+ through VF320+ configurations provide motor mounting provisions scaled to conveyor width and torque requirements. Stainless steel construction across all variants delivers superior chemical resistance and cleanroom compatibility compared to standard aluminum profiles while maintaining identical modular connection interfaces.

What installation requirements and system compatibility considerations apply to VarioFlow plus stainless steel components?

VarioFlow plus stainless steel installation requires compatible aluminum profile framework using standard T-slot connections with M8 fasteners according to ISO 4762 specifications. The system integrates seamlessly with existing VarioFlow plus aluminum components, enabling mixed-material configurations where stainless steel sections handle critical process zones. Drive holder assemblies mount directly to conveyor profiles using integrated brackets, accommodating servo motors up to 750W depending on conveyor width and application requirements. Installation maintains minimum 50mm clearance around curves to prevent payload interference, while straight sections require support spacing every 1500mm for optimal structural integrity. All electrical connections utilize IP65-rated connectors for industrial environment protection.

What safety ratings and operating parameters define VarioFlow plus stainless steel conveyor performance?

VarioFlow plus stainless steel systems operate safely within ambient temperatures from -10°C to +60°C with relative humidity up to 95% non-condensing, meeting IP54 ingress protection against dust and water spray. The stainless steel construction provides enhanced corrosion resistance in chemical environments with pH ranges from 4 to 10, exceeding standard aluminum system capabilities. Maximum conveyor speeds reach 60 meters per minute depending on payload characteristics and curve radius selection, while payload capacity scales from 25kg for 65mm width to 75kg for 320mm width systems. Safety features include emergency stop integration according to EN ISO 13849 Category 3 requirements and optional light curtain interfaces for personnel protection zones.

What maintenance schedule and service life expectations apply to VarioFlow plus stainless steel conveyor systems?

VarioFlow plus stainless steel systems require monthly visual inspection of chain tension, drive motor alignment, and fastener torque verification according to DIN EN 13306 maintenance standards. Quarterly lubrication of drive mechanisms using food-grade lubricants maintains optimal performance in hygienic applications, while semi-annual chain replacement intervals depend on operating hours and payload characteristics. The stainless steel construction delivers extended service life exceeding 15 years under normal industrial conditions with proper maintenance protocols. Critical wear components including drive chains and motor bearings require replacement every 8,000 operating hours, while structural elements maintain integrity throughout the system lifecycle with minimal degradation in corrosive environments.
