Chain conveyor system Bosch Rexroth VarioFlow plus
Assembly Technology Bosch Rexroth
The Bosch Rexroth VarioFlow+ is a flexible, multi-strand chain conveyor system engineered for continuous and intermittent material flow in assembly, test, and production environments. Chain widths span 65 mm to 185 mm, conveyor speeds reach up to 30 m/min, and the modular aluminum profile structure supports workpiece carrier loads of up to 50 kg per pallet - all fully compliant with ISO 9001 quality management requirements. The system is available in standard plastic, stainless steel (STS), and full aluminum configurations, with a dedicated ESD variant maintaining surface resistances of 10⁵-10⁹ Ω per IEC 61340-5-1 for safe transport of electrostatic-sensitive assemblies.
As an authorized Bosch Rexroth distributor, esd.equipment supplies 477 VarioFlow+ line items - conveyor chains, workpiece pallet systems (WT series), lateral guides, clamping conveyors, and dedicated tooling - from stock. The system's tool-free snap-fit assembly principle and standardized connecting elements allow rapid line reconfiguration without specialized machinery, making VarioFlow+ a benchmark for lean and Industry 4.0-ready conveyor infrastructure.
