Buying Guide For The Best Grease For Trailer Bearings

When selecting the best grease for trailer bearings, it’s essential to consider several critical factors to ensure optimal performance and longevity of your bearings. Here’s a detailed look at the key aspects to keep in mind:

1. Type of Bearing Grease

Why it Matters: The composition of bearing grease affects its ability to lubricate and protect bearings under various conditions. Different types of grease are formulated to meet specific requirements, such as resistance to water, ability to handle high temperatures, and compatibility with various materials.

What to Look For: Look for grease types specifically designed for trailer bearings, which typically include lithium complex, calcium sulfonate, or polyurea greases. These types offer good water resistance, high-temperature stability, and are suitable for the high-load conditions trailers often encounter.

2. Temperature and Pressure Rating

Why it Matters: Trailers are exposed to a wide range of temperatures and pressures, especially during long hauls or in harsh weather conditions. The grease must withstand these conditions without breaking down or losing its lubricating properties.

What to Look For: Check the grease’s temperature rating, ensuring it can handle both the high temperatures generated by the bearings under load and the ambient temperatures you expect to encounter. A high drop point (the temperature at which grease becomes liquid) of over 500°F is desirable. Additionally, ensure the grease can withstand the pressures your trailer bearings will face, indicated by its NLGI (National Lubricating Grease Institute) grade, with grades 2 or 3 being suitable for most trailer bearings.

3. Viscosity

Why it Matters: Viscosity is a measure of a fluid’s resistance to flow. In greases, it determines how well the grease will maintain a lubricating film under load and at various temperatures. Proper viscosity is crucial for ensuring the grease stays in place and provides continuous lubrication to the bearings.

What to Look For: Select a grease with a viscosity appropriate for your bearing size and the speed at which they operate. For trailer bearings, which typically operate at moderate to high speeds and under considerable loads, a grease with a medium to high viscosity index is ideal. This ensures the grease maintains its protective film over a wide temperature range without becoming too fluid or too stiff.

4. Base Oil

Why it Matters: The base oil is a critical component of grease, significantly affecting its overall performance. It determines the grease’s resistance to oxidation, its operating temperature range, and its ability to lubricate under various conditions. The choice of base oil impacts the grease’s suitability for specific applications, including the high demands of trailer bearings.

What to Look For: Identify the type of base oil used in the grease, which can be mineral, synthetic, or a blend of both. Synthetic oils generally offer better performance at extreme temperatures and have superior oxidation stability compared to mineral oils. Look for base oils with a high viscosity index, indicating their ability to maintain effective lubrication over a broad temperature range. The specific application of your trailer (e.g., long-haul vs. short trips, exposure to extreme conditions) will guide your choice.

5. Thickener

Why it Matters: The thickener acts like a sponge, holding the base oil in place and releasing it gradually to lubricate the bearings. The type of thickener used affects the grease’s temperature tolerance, water resistance, and mechanical stability.

What to Look For: Common thickeners include lithium, lithium complex, calcium sulfonate, and polyurea. Lithium and lithium complex greases are popular for their good performance in a variety of conditions, including being suitable for high-temperature applications. Calcium sulfonate greases offer excellent water resistance and are ideal for trailers frequently exposed to wet conditions. Polyurea greases are known for their high-temperature stability and long service life. Choose a thickener compatible with the environmental and operational conditions your trailer bearings will face.

6. Quantity

Why it Matters: The quantity of grease you need is determined by the size of your trailer’s bearings and the frequency of maintenance. Buying the correct quantity ensures you have enough grease for regular maintenance while avoiding waste or the need for frequent purchases.

What to Look For: Grease typically comes in tubes for grease guns, smaller tubs, or larger buckets. Consider the number of bearings you need to maintain and the recommended service intervals. For most personal or light commercial use trailers, tubes may be sufficient. However, for fleets or multiple trailers, larger quantities can be more cost-effective. Ensure you select a quantity that matches your maintenance schedule and the number of trailers you’re servicing.

Grease for Trailer Bearing – FAQs

1. What is the best type of grease to use for trailer bearings?

Ans: The best type of grease to use for trailer bearings would be the one with a high-quality compound offering water resistance along with a reduction in friction. There are a lot of grease compounds available on the market, but not all options are specifically designed for wheel bearings. These types of grease are formulated to withstand the high temperatures and heavy loads experienced by trailer bearings and can help to prevent corrosion and wear on the bearings. It is important to choose a grease that meets the manufacturer’s recommended specifications for your trailer’s bearings.

2. How often should I grease my trailer bearings?

Ans: It is generally recommended to grease trailer bearings every 10,000 to 12,000 miles or every year, whichever comes first. This can vary depending on the specific conditions in which the trailer is used, such as the amount of weight being carried and the frequency of use. It is important to regularly check and maintain the bearings to ensure optimal performance and extend their lifespan. If you notice any unusual noise or vibration coming from the bearings, it is a good idea to have them checked out and possibly re-greased sooner rather than later.

3. Can I use regular automotive grease for my trailer bearings?

Ans: While regular automotive grease may be suitable for use in some applications, it is generally not recommended for use in trailer bearings. Trailer bearings are subjected to higher loads and temperatures than most automotive applications, and regular automotive grease may not provide sufficient protection or performance in these conditions. It is best to use a high-quality, water-resistant grease specifically designed for wheel bearings to ensure optimal performance and protection for your trailer bearings. Using the wrong type of grease can lead to premature bearing failure and costly repairs.


In our guide, we’ve carefully selected the best greases for trailer bearings, focusing on factors like viscosity, base oil, thickener, and additives. Here’s a brief overview:

  • Super Lube Grease: Ideal for quick maintenance tasks, this synthetic, multi-purpose, food-grade grease is perfect for small applications.
  • Lucas Oil Red”N” Tacky Grease: With its smooth texture and red lithium complex, this grease provides excellent rust and oxidation protection. It’s versatile for various uses beyond just trailer bearings.
  • Plews & Edelmann Marine Grease: This grease uses calcium sulfonate for superior lubrication and can withstand temperatures up to 550°F, making it great for different weather conditions.

Choose based on your trailer’s needs and how often you’ll use the grease, ensuring compatibility and optimal performance.
