Bearings are commonly used in trailer parts such as between your brake drum, discs or hubs. They consist of two parts, the cup and the cone, which are pressed into the hub to aid smooth, rolling rotation for your wheels during towing.
In each hub, there are two pairs of bearings, one for the outer and one for the inner, both of which have one cup and one cone. The outer bearings pair (closest to the curb) are the smallest and the inner bearing pair (closest to the trailer) are the larger bearings. The inner bearings are matched with an oil/grease seal to perfectly fit and prevent lubricants from escaping the bearings.

When building or repairing a trailer, bearings can be a complex part to break down. Using the table below, we’ve provided a chart which provides information to find out which bearings you need. It includes bearing numbers, the OD (outer diameter) and ID (inner diameter) as well as the width, which should make finding the part you need as easy as possible.
How to Check What Bearings I Need?
If you’re looking to find the trailer bearing numbers on your trailer, there are a few different ways to go about it. Here are a few tips to help you locate the information you need:
- Check the owner’s manual: Many trailers come with an owner’s manual that includes information about the bearings. If you still have the manual, it’s worth checking to see if the bearing numbers are listed.
- Look for a label or sticker: Many trailers have a label or sticker on them that includes the bearing numbers. This label or sticker may be located on the axles or on the frame of the trailer.
- Inspect the bearings: If you can’t find the bearing numbers through the above methods, you may need to inspect the bearings themselves. The bearing numbers are typically stamped on the bearings.
- Contact the manufacturer: If you’re still having trouble finding the bearing numbers, you can contact the manufacturer of your trailer. They should be able to provide you with the information you need.
- Use online resources: Lastly, you can try searching online for resources that can help you find the bearing numbers on your trailer. There are many forums, FAQ sections, and online guides available that can help you find the information you need.
The Importance of Bearing Maintenance
Let’s discuss the importance of regular maintenance for trailer bearings. Trailer bearings should be inspected and lubricated at least once a year, or more frequently if you use your trailer frequently or for long distances. This can be done by a professional mechanic or by yourself, with the right tools and knowledge.
When inspecting your trailer bearings, look for signs of wear and tear such as discoloration, rust, or damage to the seals. If you notice any of these issues, it’s time to replace the bearings. It’s also important to note that if you experience issues with vibration or noise while towing your trailer, this could be a sign that your bearings need to be replaced.
Picking The Right Bearings
When it comes to choosing the right bearings for your trailer, there are a few factors to consider. The first thing to consider is the size and weight of your trailer. The bearings that are suitable for a small utility trailer may not be suitable for a large horse trailer. It’s also important to consider the type of terrain and weather conditions your trailer will be exposed to, as this can affect the durability of the bearings.
Another important factor to consider when choosing trailer bearings is the quality of the bearings. It’s important to choose bearings from a reputable manufacturer that are known for their durability and quality. Avoid buying low-quality bearings as they may not last as long and can cause more damage to your trailer in the long run.
