Jockey Wheels

ATE UK have been supplying parts, components and spares for trailers and other towable equipment since 1995, and have earned a strong reputation as one of the UK’s leading innovative and progressive independent distributors of parts and equipment for trailers and towed equipment.

One of the most frequently asked for replacement parts is for jockey wheels. Jockey wheels are an essential piece of equipment for both caravans and trailers alike, as it allows the trailer to be easily manoeuvred when not attached to the towing vehicle while ensuring that the A-frame or drawbar is kept from the ground: vital for hitching and unhitching your caravan or trailer.


By the very nature of their function, jockey wheels carry a lot of weight and are designed to be height adjustable so that your back doesn’t have to take the strain, but this also means that they are susceptible to damage from wear and tear. The design of jockey wheels has evolved over the years, and we stock models that have built-in load indicators so that you never exceed the maximum load weight, and models which have a safety support chain to prevent them from dropping down during transit: another reason why replacements are often needed.

If your jockey wheel has become disconnected or damaged during your journey, you can take advantage of our early bird next day delivery service that guarantees that you will receive your replacement jockey wheel or parts before noon, so that your journey disruption can be kept to a minimum. We offer our customers a range of jockey wheel solutions from a variety of leading brands such as Motion, Bradley & Alko: from complete jockey wheel sets to jockey wheel spares.

Why Does My Jockey Wheel Keep Getting Damaged?

The most common reason for jockey wheels to get damaged is that they have slipped down to the road surface during transit. You must ensure that it is raised and adequately tightened to prevent this from occurring. For repeat offenders, consider replacing the jockey wheel with a model that has a safety chain or one that has a serrated outer sleeve, as the serrations restrict the opportunity for movement. If you replace your jockey wheel with the serrated option, you will also need to purchase the appropriate clamp.

When was the last time you serviced your jockey wheel? Although they contain few components, you should annually inspect jockey wheels to ensure that it is working efficiently to avoid damage. A stiff handle and jolting action or a wheel that is seizing up can be a sign that the ball bearings need attention: cleaning and some grease. If the bearings seise up, you may have to replace the spindles, so it is worth spending time maintaining your equipment to increase its longevity.

Which Jockey Wheel Do I Need?

The first question that needs to be answered is what do you need it for? Jockey wheels range from medium to heavy-duty construction, and if you are using one for a caravan, your needs are going to be different to those for using a commercial trailer. When replacing your jockey wheel completely or just part of it, you need to take specific measurements to ensure that you are buying the correct option.

·         Length of the jockey wheel

Measure the fully extended jockey wheel from the handle to the ground, and again when it is fully wound up. If you are replacing like for like, these measurements will help you replicate your current setup; however, if you are considering changing to a different length of jockey wheel, it can impact on the functionality of your rig. For example, hulls extend over the boat trailer’s A-frame, and a longer jockey wheel may damage the boat during its loading and transport. Similarly, a jockey wheel that is too long may prevent the front compartment of a caravan from being able to open.

·         The diameter of the jockey wheel sleeve

Here is a guide as to popular diameters and trailer usage. Remember, if you are unsure about which sleeve diameter you need, contact one of our specialist staff to guide you through the options that are available.

a)    35mm: light-weight trailers

b)    42mm: larger trailers and some unbraked boat trailers

c)     48mm: the most commonly used diameter size for commercial and caravan trailers

d)    60-63mm: heavy-duty commercial trailers


The Jockey Wheel Tyre

If you are replacing the wheel itself, measure the width of the wheel. You will need this measurement to ensure that the replacement you buy can fit within the existing jockey wheel clamp. You may be taking this opportunity to change the type of jockey wheel tyre. There are pros and cons to each style, and you need to consider how you use your trailer to make the best choice. Solid tyres are better on hard ground surfaces, but pneumatic tyres are more appropriate to gravel, grass, beaches and other loose surfaces.

You also have the option of either steel or plastic wheel centre. The plastic wheel centre is appropriate for light trailers, unbraked trailers and small caravans, but more heavy-duty and commercial vehicles benefit from steel centres.
