Tonne-class industrial casters.
Past a point, 'heavy duty' stops describing the product. This series starts at 1,250 kg per caster: extra-wide 58 mm wheels on a reinforced plate fork, for equipment measured in tonnes.
Specification
| Series | Tonne-class industrial casters |
|---|---|
| Wheel | 75–125 mm diameter × 58 mm width (wheel material confirmed on the quotation) |
| Load capacity | 1,250–1,600 kg per caster by size — see the size table |
| Configurations | Swivel, rigid, swivel with brake |
| Mounting | Top plate 110 × 90 mm, hole spacing 85 × 61 mm, hole Ø 11 mm |
| Documentation | CE / RoHS documentation available on request — ask in the RFQ and the documents for this series accompany the quotation. |
| MOQ | Confirmed per order in the written quotation |
| Lead time | Confirmed per order in the written quotation |
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.
These are the casters under heavy fabrications, plant machinery, large moulds and dock equipment — loads where a failed wheel is a safety event, not a maintenance ticket. The series uses an extra-wide wheel (58 mm across all three sizes) to keep ground pressure sane, and a single heavy plate standard so the mounting is never the weak point.
Size the series the way the load math demands: total loaded weight divided by three, then the first size whose per-caster rating clears it. At these capacities the sample stage is not a formality — the production sample is load-tested against the locked specification before bulk production is approved.

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.
Configuration options
- Swivel, rigid and brake builds on the same plate standard.
- For the same loads on a floor-protective tread, compare the iron-core PU series.
- Machinery-skate and multi-caster layouts quoted against your equipment drawing — send it with the RFQ.
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
How many casters does a 4-tonne machine need?
By the floor rule: 4,000 kg ÷ 3 = 1,334 kg per caster — the 5 inch size at 1,600 kg, on four casters, with the margin the ÷3 rule already builds in. State the machine and floor in the RFQ and the quotation will show the same maths.
Can these be used outdoors?
State the environment in the RFQ — fork finish and bearing sealing are part of the locked specification at this class, and outdoor duty changes both.
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.
