ESD Castors and Wheels
Storage Solutions
ESD rollers and ESD castors are engineered to maintain a controlled surface resistance of 10⁵-10⁹ Ω throughout the entire load path - from shelf frame to floor ground point - preventing electrostatic discharge events that can destroy CMOS and MOSFET components with as little as 100 V. Conductive polyurethane or rubber tread compounds are vulcanised onto static-dissipative hubs, ensuring charge bleed-off conforms to IEC 61340-5-1 and EN 61340-4-4 even under dynamic rolling loads of 50-200 kg per wheel.
As a specialist distributor for EPA-compliant workstation and storage solutions, esd.equipment stocks ESD rollers and castors from leading manufacturers, covering swivel castors, fixed castors, braked variants, and heavy-duty versions for rack and trolley systems. All products are verified against DIN EN 61340-5-1 and IEC 61340-5-2 to support full EPA documentation and audit trails.
