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
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.

Frequently Asked Questions
What surfaces are these castors suitable for?
These castors are designed for use on smooth, hard floor surfaces such as tile, laminate, vinyl, and sealed concrete. The polypropylene wheel rolls cleanly and quietly on flat indoor surfaces, making it well suited to retail, office, and light workshop environments.
How many castors do I need, and what is the combined load capacity?
Most applications use a set of four castors. With a single castor rated at 55kg, a set of four provides a combined maximum load capacity of 165kg — calculated using three castors to allow for uneven weight distribution. Always ensure the total load of your application does not exceed this figure.
What fixings are required to install this castor?
This castor is mounted using four bolts through the top plate. The hole centres measure 36mm x 36mm with a hole diameter of 6mm, accepting standard M6 bolts. Fixings are not included and should be sourced separately to suit your specific application.
Is this castor available with a brake?
This listing is for the swivel castor without a brake. If you require a locking castor to keep equipment stationary when not in use, a braked version in the same 50mm pressed steel range is available separately in our store.
Sold individually. Fixings not included. For best results, use on smooth, level indoor surfaces. If you require a braked version or a higher load-rated castor, please browse our full range of pressed steel castors.
