Extra heavy duty iron-core PU casters.
The PU-on-cast-iron formula at its strongest: 100 to 200 mm wheels with both ratings on the table — dynamic 400 to 700 kg for rolling duty, static 800 to 1,200 kg standing.

This series prints the two numbers most catalogues merge into one. The dynamic rating is what the caster carries rolling; the static rating is what it carries standing still. Buyers who size from a static headline for a rolling application under-spec the caster by a factor of two — this series states dynamic first and lets the static figure inform standing-load checks, which is the honest order.
The wheel is the heavy duty standard — polyurethane tread bonded to a cast iron core — in a reinforced fork on a 137 × 110 mm plate. It is the series for heavy racks, plant carts and equipment that rolls loaded every day.

Size from the dynamic column for anything that rolls; the static column is for standing-load checks only. 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.
- Spring-suspended build for shock floors — see the spring shock absorbing series.
- Private label and carton marks under the OEM programme.
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
Which rating do I size from?
Dynamic, for anything that moves. The static figure is roughly double — sizing a rolling application from it is the most common heavy-caster mistake we see, and the reason this table prints both.
How does this series relate to the core heavy duty line?
Same wheel formula, heavier build: bigger plate, wider fork, higher ratings. The core line covers everyday carts; this series takes over where its ratings end.
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.
