Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.

- Cushions the load and soaks up vibration

Details & FAQs
Ball Furniture Castor
This 40mm swivel ball castor has a bright zinc-plated metal hood over a grey rubber wheel on a polypropylene centre, rated at 20kg per castor. The rounded ball shape hides the wheel neatly, giving light furniture a tidy, classic look while the rubber tread rolls quietly.
It fits with an M8 x 13mm threaded stem that screws into an M8 insert, tee nut or socket under the furniture. The swivel head turns a full 360 degrees, so small tables, stools, plant stands and side units move and turn easily at home, in offices and in hotels.
