Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
Enter the weight of the item plus its heaviest load. This castor is rated 55 kg each.
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.

Details & FAQs
This 50mm pressed steel swivel castor with brake is a compact, light-duty mobility solution designed for everyday use across a wide range of indoor environments. Fitted with a black polypropylene wheel and secured via a 4-hole top plate, it delivers smooth, controlled movement on hard floor surfaces — with a side-operated brake that locks the wheel firmly in position when required. With a 55kg individual load capacity, it is well suited to shop fitting, light furniture, display units, trolleys, and general-purpose equipment where reliable, quiet rolling performance is essential.

Frequently Asked Questions
What is the maximum weight this castor can support?
Each castor has an individual load capacity of 55kg. When four castors are used together on a single piece of equipment, the combined maximum load capacity is 165kg. It is recommended to stay within these limits to ensure safe and reliable performance.
Is this castor suitable for use on hard floors such as wood, tile, or laminate?
Yes. The black polypropylene wheel is designed for use on smooth, hard floor surfaces including timber, tile, vinyl, and laminate. It rolls quietly and cleanly without leaving marks under normal light-duty use conditions.
How is this castor fixed to equipment, and what fixings are required?
The castor is mounted using a 4-hole top plate measuring 50mm x 50mm, with hole centres of 36mm x 36mm and a hole diameter of 6mm. Standard M6 bolts are typically used for fixing. The plate is zinc-plated pressed steel, providing a strong and corrosion-resistant mounting point.
How does the brake mechanism work on this swivel castor?
The brake is a side-operated foot brake that engages directly onto the wheel to prevent rotation. When applied, it locks the castor in place, keeping equipment stationary on flat surfaces. It is released by pressing the opposite side of the brake lever. This type of brake is suitable for static positioning rather than heavy-duty braking applications.
* All dimensions are nominal and measured in millimetres unless otherwise stated. Load capacities are quoted for static conditions on flat, level surfaces. For dynamic or mobile load applications, consult load ratings carefully and select an appropriate safety margin.
