ESD (electrostatic discharge) and conductive casters dissipate static charge from rolling equipment to help prevent damage to electronics, ignition in explosive atmospheres, or interference in sensitive instrumentation. Conductive casters provide direct path-to-ground (resistance < 10⁴ Ω); static-dissipative casters are slower discharge (10⁵–10⁹ Ω). Both are commonly used in electronics manufacturing and explosive-atmosphere environments. Contact our team for official manufacturer documentation and specifications.

Common Applications
- Electronics manufacturing — PCB assembly, component handling
- Aerospace avionics assembly and test stands
- Cleanroom semiconductor and biotech equipment
- Explosive atmospheres (paint booths, solvent-handling, ammunition)
- Pharmaceutical filling and aseptic processing
When to Choose ESD / Conductive Casters
- Your facility maintains a documented ESD-protected area
- Equipment carries or contacts sensitive electronics
- Operating environment is an explosive atmosphere (paint, solvent, etc.)
- Existing audit findings flag static accumulation risk
