How to choose the right product – A step by Step guide
We all know that the most important thing when ordering your wheels and castors, is to make sure it’s fit for purpose, but what do you need to be mindful of? We are going to take you through a step by step guide of what is important, and what specific type of castor you’ll need. For instance, industrial castors, transport castors, castors for hospitals and medical use, or flight cases wheels and castors.
Know your weight
We’re not asking you to pop on the scales yourself, but you need to know the load your wheels will be carrying. Then divide this number by three. Yes, three. I know what you’re thinking… there are four wheels! Yes, there are, but should there be a ramp or uneven floor there will always be three points of contact with the ground, so that’s why we advise you divide by three. This is the weight you need to look for. This will also determine what sort of wheel you get, whether it be roller bearing, or ball bearing, or plain bore. The better the bearing the easier it is to start the wheel in motion, which is what you want for a heavy load.
What terrain are you going over?
This will determine what tyre material is required. Firstly are you using the wheels outdoors? If you are you don’t want to use polypropylene wheels as nylon fair better with water. Are you going to be going over rough terrain such as tiles, or rolling within a factory which could have debris on the floor? The rougher the floor the softer wheel you want. If the floor is hard such as stone you can use a harder wheel, though grip can be an issue. If you don’t want to leave marks on the floor such as in a theatre or on a lovely marble floor you want a softer tyre not made of a synthetic rubber, which are specially designed to not leave marks.
What does it need to be attached to?
This is important when picking your castors. There are two main options for your consideration; A Square ‘Top Plate’ or a round ‘Bolt Hole’. The Square Top Plate utilizes 4 attaching holes which are normally used on the four corners of a flat bottom trolley, stillage, roll cage etc. These provide excellent stability and durability. Bolt Hole brackets use only one attaching hole, through this hole we can utilise a threaded stem, expander or a solid stem. These will then be fitted to units will a leg like a table or workbench. Bolt Hole brackets are quick to install but less stable than the Top Plate alternative, also its worth considering they are ordinarily used for lighter duty loads.
What do you need it to do?
If you plan to use it for something which you are going to manoeuvre often such as a shopping trolley you will need swivel wheels, if you are only going short distances in straight lines you can use a combination of swivel and fixed castors.
This is the basics of what you need to know to select your wheel, there are other options such as sandwich wheels but if you are struggling why not give our friendly technical team a call who can help you find what you’re looking for.
