Choosing the Right Castors

We advise that the first thing you need to do is choose your wheel, this will determine what other options you have when it comes to brackets.

This part of the process can be quite intimidating as there are lots of different options, our general advice is to use a soft wheel on a hard floor and vice versa. If you have any questions, our highly experienced team are here to offer expert advice.

To choose your wheel you’ll need to know what size of everything you need, so it’s time to get your measuring tape out…

Measure your wheel’s diameter

You need to have a look at the bracket and see if it has a top plate (attached to your apparatus with 4 bolts) or a bolt hole fixing (attached by one bolt).

 If you’re designing a new product, just decide how you want to fix it to your apparatus and take into consideration the weight that it needs to carry.

Then you need to consider dimensions. What size plate do you want/need for your application, or measure the one that you already have.

Don’t forget to measure the distance between the bolt holes in a top plate castor.

Measure the diameter for the bolt hole castors and the diameter of the hole.

If you’re attaching your castor into a round or square tube, you will need a tube adapter, we stock these in a range of different sizes to suit every possibility.

All you need to know now, is how many of each you need on your application…The most popular configuration of brackets are as follows:

Four Swivel Castors – great manoeuvrability but sometimes difficult to control and therefore not great for heavy loads.

Two Swivel Castors and Two Fixed Castors – by far the most popular option, easy to steer and control

Two Swivel Castors with Brakes and Two Fixed Castors- the same as above but with the ability to lock the wheels

Now all you need to do is check your load capacity.

To work this out you need to take into consideration the weight of the apparatus and the load that it carries, then divide this by three, yes three. This will be the load you want each castor to be able to withstand. 

Why divide by three you ask? Well, this is a safety feature as there are always three points of contact insuring that you won’t overload the castors. This allows for uneven surfaces.
