Anti-static casters — medium duty.
For carts and equipment that work around electronics: this series is built for static-control environments, on the standard medium duty frame. Three sizes at 90 to 100 kg per caster.

Values marked as a class or target are the specification this model is quoted and sampled against. Final confirmed values are stated on the written quotation and verified on the production sample before bulk production.
Static discharge is an invisible defect generator in electronics assembly, repair and packaging. Casters are part of the ESD chain — a cart that insulates its load from the floor breaks the path to ground. This series is the anti-static build of the medium duty platform, for ESD-protected areas and the carts, racks and workstations that move inside them.
One honesty note, because this category attracts invented numbers: the series table states sizes and loads, and we do not publish a resistivity figure we have not locked with you. If your ESD programme specifies a resistance range, state it in the RFQ — the sample is then checked against your stated requirement, and the confirmed value goes on the written quotation.
Sizes in this series
| Size | Wheel Ø × width | Load per caster | Overall height |
|---|---|---|---|
| 3 in | 75 × 32 | 90 kg | 105 mm |
| 4 in | 100 × 32 | 95 kg | 130 mm |
| 5 in | 125 × 32 | 100 kg | 155 mm |
Dimensions in millimetres unless shown otherwise. Values are the series table values; the written quotation confirms the final drawing for your size class before sampling.

- Standard TPR build of the same frame — see the medium duty TPR series.
What the sample verifies
Before bulk production, the production sample of this series is checked against the locked specification: wheel diameter and — critically — wheel width measured, tread hardness verified where the series states it, bearing type confirmed, fork and plate dimensions measured, and load performance tested per the stated convention (EN 12532 / ANSI ICWM). The approved sample becomes the reference for the shipment, and the order carries batch traceability back to it.

About this series
What resistance should I specify?
Whatever your ESD control programme (for example an ANSI/ESD S20.20-based plan) requires for mobile equipment. State the range in the RFQ; the sample is measured against it and the result is recorded on the quotation.
Do anti-static casters need a drag chain as well?
That depends on your floor and your programme's verification method — tell us the floor type in the RFQ and we will quote the configuration your programme can actually verify.
Need this caster under your own brand?
Private label, custom packaging and carton marks are available across the range — mention it in the RFQ and the quotation will include the branding steps.
