How Bearing Buddies Work

If you're a trailer owner, you understand the importance of maintaining your equipment to keep it in good working order. One component you don't want to overlook is the wheel bearings. These essential parts allow your trailer wheels to spin freely and support the weight of your cargo. To prevent damage and ensure proper lubrication, many trailer owners turn to bearing buddies. But how do bearing buddies work, and are they the right choice for your trailer? In this article, we'll explore the ins and outs of bearing buddies so you can make an informed decision about whether they're a good fit for your trailer maintenance routine.

What are Bearing Buddies?

Bearing buddies are a type of wheel bearing protector designed to keep water and dirt out of trailer wheel bearings. They consist of a housing that fits over the end of the axle, a spring-loaded piston, and a grease fitting. When the wheel bearings are properly packed with grease, the piston compresses slightly, creating a slight pressure inside the housing. This pressure helps to prevent water from entering the bearings, which can lead to corrosion and premature wear. The grease fitting allows you to easily add more grease as needed, ensuring that the bearings remain properly lubricated.

The design of bearing buddies allows for easy maintenance and helps extend the life of your wheel bearings. Properly installed bearing buddies can help prevent costly repairs and keep your trailer rolling smoothly down the road.

How Bearing Buddies Work

When your trailer is in motion, the heat generated by the spinning wheels can cause the air inside the housing to expand. This expansion creates a slight outward pressure, which helps push any water or moisture away from the bearings. When the trailer is at rest and cools down, the air inside the housing contracts, creating a slight vacuum that helps draw any moisture away from the bearings. In this way, bearing buddies work to protect your wheel bearings from the elements, prolonging their life and reducing the need for frequent repacking.

To ensure that your bearing buddies are functioning properly, it's essential to inspect them regularly and add grease as needed. Over time, the grease inside the housing may break down or become contaminated, reducing its effectiveness. By keeping an eye on your bearing buddies and topping up the grease as needed, you can help ensure that your wheel bearings remain well-protected and properly lubricated.

Benefits of Using Bearing Buddies

There are several benefits to using bearing buddies on your trailer. One of the most significant advantages is the protection they provide to your wheel bearings. By keeping water and dirt out, bearing buddies help prevent corrosion and reduce the risk of premature wear. This can extend the life of your wheel bearings and reduce the likelihood of breakdowns or other issues while you're on the road.

Another benefit of bearing buddies is the ease of maintenance they provide. Adding grease to your wheel bearings can be a messy and time-consuming task, but bearing buddies streamline the process. With a grease gun and a few pumps, you can quickly and easily add grease to the housing, ensuring that your wheel bearings remain well-lubricated and protected.

In addition to these practical benefits, bearing buddies can also provide peace of mind for trailer owners. Knowing that your wheel bearings are well-protected can give you added confidence as you tow your trailer, whether you're heading across town or across the country.

Considerations for Using Bearing Buddies

While bearing buddies offer many advantages, it's essential to consider whether they are the right choice for your trailer. One consideration is the type of trailer you have. Bearing buddies are designed for use on trailers with axles that have a hub that is 'conventional' in the sense that it is neither a marine hub nor a hubs inserted with removable spindles.

Additionally, you'll want to consider your trailer usage. If your trailer spends a significant amount of time submerged in water, such as a boat trailer, bearing buddies may not be the best option. In these cases, marine-grade wheel bearing protectors may be a more suitable choice.

It's also important to note that bearing buddies are not a substitute for proper wheel bearing maintenance. While they can help protect your wheel bearings, they do not eliminate the need for regular inspections and repacking of the bearings. It's crucial to follow the manufacturer's recommendations for wheel bearing maintenance and ensure that your bearings are in good condition.

Finally, it's essential to properly install and maintain your bearing buddies to ensure that they are effective. This includes using the correct size for your wheel hub, ensuring a proper seal, and adding grease as needed. If you're unsure about the installation or maintenance process, it's a good idea to consult with a professional or refer to the manufacturer's guidelines.

Conclusion

Bearing buddies offer a convenient and effective way to protect your trailer's wheel bearings and keep them properly lubricated. By creating a barrier against water and dirt and simplifying the grease maintenance process, bearing buddies can help extend the life of your wheel bearings and reduce the risk of breakdowns while you're on the road.

As with any trailer maintenance component, it's essential to consider your specific trailer and usage when deciding whether bearing buddies are the right choice for you. By understanding how bearing buddies work and considering their benefits and limitations, you can make an informed decision about whether to incorporate them into your regular maintenance routine. Proper installation, maintenance, and periodic inspections are essential to ensure that your bearing buddies are performing as intended and providing the protection your wheel bearings need.
