ESD / Conductive Casters

Static-dissipative for electronics and explosive atmospheres

In Stock — Miami Warehouse Same-Day Will-Call ANSI MH28.3 Compliant

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.

Frequently Asked Questions

Conductive or static-dissipative — how do I choose?
For electronics manufacturing, static-dissipative (10⁵–10⁹ Ω) is the typical default — slow controlled discharge avoids damage from rapid grounding. For explosive-atmosphere applications, full conductive (<10⁴ Ω) helps prevent static spark accumulation. When in doubt, your facility ESD officer or safety engineer specifies the resistance band; we provide the matching SKU.
How do ESD casters maintain conductivity in service?
Conductive carbon-loaded compounds maintain a continuous electrical path from wheel surface through the rig to the equipment frame (which is grounded through floor or bonding strap). They do NOT require lubrication or recharging. Service-life monitoring is by periodic resistance check (annual or per facility ESD program). Replacement is required when measured resistance drifts outside the specified band.
