Bosch Rexroth VarioFlow plus stainless steel system - TEC
Chain conveyor system Bosch Rexroth VarioFlow plus
The Bosch Rexroth VarioFlow plus Stainless Steel System delivers a corrosion-resistant chain conveyor solution built to IEC and DIN EN hygiene and cleanroom standards. All contact components are manufactured from 1.4301 (AISI 304) or 1.4404 (AISI 316L) stainless steel, achieving surface roughness values of Ra < 0.8 µm for CIP/SIP-compatible cleaning cycles. The modular track profiles support chain widths of 63 mm, 83 mm, and 103 mm, with conveyor speeds continuously adjustable from 1 to 30 m/min and maximum distributed loads up to 50 kg/m.
As an authorized Bosch Rexroth distributor, esd.equipment stocks 17 VarioFlow plus Stainless Steel components - including straight tracks, curves, drives, and transfer units - fully compatible with the standard VarioFlow plus portfolio. All system components comply with EU Machinery Directive 2006/42/EC, FDA 21 CFR food-contact guidelines, and EHEDG hygienic design principles, making this range the first choice for regulated manufacturing and assembly environments.
