Chain conveyor system Bosch Rexroth VarioFlow plus - ESD (antistatic)
Assembly Technology Bosch Rexroth
The Bosch Rexroth VarioFlow+ is a modular plastic chain conveyor system engineered for continuous and accumulation transport in assembly and production lines. Chain widths range from 63 mm to 320 mm, conveyor speeds reach up to 30 m/min, and individual pallet loads of up to 50 kg are supported - all within a single, scalable track profile. The system accommodates straight runs, curves (15°, 30°, 45°, 90°), inclines, and transfers without changing the base profile, meeting the flexibility demands of lean manufacturing layouts. Available variants include standard aluminium (AL), stainless steel (STS) for cleanroom and food-grade environments, and a dedicated ESD system with surface resistance 10⁵-10⁹ Ω per IEC 61340-5-1 for electrostatic-sensitive device handling.
As an authorised distributor for Bosch Rexroth assembly technology, esd.equipment stocks 477 VarioFlow+ components covering drive units, conveyor chains, side guides, workpiece carrier systems (WT), clamping conveyors, and all associated tooling. Products comply with DIN EN ISO 9001 quality management standards and are compatible with the broader Bosch Rexroth MPS and TS 2plus/TS 5 pallet transfer ecosystem, enabling fully integrated line configurations.
