3. Three minute comparison table: prioritize these 5 items when selecting
| Comparison | Conductive Caster | Anti-static Caster |
| Resistance range (typical) | ≤ 10 ⁴ Ω (lower resistance) | 10 ⁵ -10 ⁹ Ω (dissipation range) |
| Charge release | Faster guidance and prevention of accumulation | Slow dissipation, controlled potential |
| Grounding requirements | Usually relies more on conductive ground/grounding systems | The general requirements are relatively low, but insulation partitions still need to be avoided |
| Core purpose | Explosion proof/ESD breakdown prevention (high-risk) | Anti dust/anti micro discharge interference (medium low risk) |
| Typical industries | Oil and gas/chemical/dust explosion, ultra clean semiconductor | Instrument transportation, general electronics factory, machine room/server handling |
4. Typical application: Choose more stable based on risk level
1). More recommended scenarios for conductive casters:
Flammable and explosive: paint spraying, solvent storage, oil and gas field stations, dust explosion risk workshops.
Ultra clean/semiconductor: chip manufacturing, packaging testing, critical ESD workstation turnover vehicle.
2). More recommended scenarios for anti-static casters:
Transportation of precision instruments and medical equipment: reducing interference from electrostatic suction and micro discharge.
General electronic manufacturing: SMT turnover vehicles, accessory vehicles, and machine room equipment handling (risk not classified as explosive).
5. Selection checklist: Write these 6 pieces of information into the inquiry form to double communication efficiency
1). Electrostatic risk level: whether it is flammable and explosive/whether it is a chip level sensitive device (determining conductivity vs. dissipation).
2). Target resistance range: specify the “conduction/dissipation” and expected range, and require a testing report.
3). Ground conditions: whether there is a conductive floor/grounding grid; Humidity range (static electricity is more pronounced in extremely dry conditions).
4). Load capacity and frequency: total weight, single wheel dynamic load, daily pushing distance/frequency (determining wheel diameter, wheel width, and bearings).
5). Structure and installation: fixed/universal, brake/directional lock, installation hole spacing/aperture/total height/offset.
6). Maintenance requirements: Is it possible to regularly clean the oil stains on the wheel surface, retest the resistance regularly, and check the grounding link.
Conclusion:
The difference between electric casters and anti-static casters is not in the name, but in the “resistance level and grounding link”. In high-risk scenarios, it is important to quickly dissipate the charge and choose conductivity; Generally, static control requires stable dissipation and anti-static measures should be chosen. Don’t forget: Once the grounding link is insulated (oil stains, coatings, plastic partitions, non-conductive bearings), even the best wheels may fail.
