About Castors UK
We do one thing: castors, wheels and the fittings that go with them. That focus means a deeper range, straighter answers and the right castor first time, whether you need four furniture castors or a full set for a 12-tonne container.

General suppliers stock a handful of castors. We stock the whole problem: every size, load, wheel, fixing and brake in one place, plus people who can tell them apart.
A castor that is under-rated, too hard for the floor or the wrong fixing costs you twice: once to buy and again to replace. Every product page shows the load per castor, plate and hole centres, overall height and swivel radius so you can check fit before you order.
From 25mm bolt hole castors to 525mm super-elastic wheels, stainless steel for washdown, anti-static for electronics and heat-resistant for ovens and bakeries, the specialist variants are stocked alongside the everyday ones.
Not sure what you have? Send a photo of the old castor on WhatsApp or tell us the load, floor and fixing, and we will match it or recommend a better option.

Load, floor and fixing are the start. These are the questions we ask next, and the ones that separate a castor that lasts from one that fails early.
Standard rubber and polyurethane treads are typically rated to +60°C to +80°C. For ovens and bakeries, choose phenolic (up to around +280°C on some models) or high-temperature cast iron. Washdown areas call for stainless steel. Electronics and flammable atmospheres may need conductive or anti-static wheels. Every product page lists its temperature range.
General industrial castors are rated for use up to walking pace, 4 km/h (ISO 22883). If a trolley is towed, runs in a tugger train or moves faster than walking pace, it needs castors rated for that duty (ISO 22884 covers up to 16 km/h), so tell us before you order.
A wheel brake stops the wheel turning. A total-lock brake stops both the wheel and the swivel, so the castor cannot rotate. A directional lock holds a swivel castor straight for long runs, then releases it for steering.
Plain bore is simple and cheap for light, slow use. Roller bearings suit heavier loads. Ball and precision ball bearings roll with the least effort and suit long distances or frequent moves.
Hardness is measured on the Shore scale. Softer treads (lower Shore A) grip, cushion and protect floors; harder treads roll more easily under heavy loads. We list tread hardness where the manufacturer publishes it.
Check the overall height from floor to fixing and the swivel radius, the circle a swivel castor sweeps as it turns. Too little clearance and castors clash with the frame or each other.
When a manufacturer quotes a load rating, it was tested against a standard. Knowing which one tells you what that rating means in practice. The international ISO series below covers castors and wheels, and runs alongside the European EN 12526 to EN 12533 series, published in the UK as BS EN.
Why it matters: a load rating assumes the conditions in the standard, including speed. A castor rated for 4 km/h hand-pushed use is not rated for towing. We show each manufacturer's rated load per castor on every product page and can advise on which rating applies to your use.
