5th Wheel Grease

5th wheel grease is a heavy-duty lubricant specifically formulated for use on fifth wheel couplings found on articulated trucks and trailers. It is designed to withstand high pressures, constant friction, and exposure to outdoor elements, ensuring smooth articulation between the tractor and trailer units. This grease typically has a tacky, adhesive texture, helping it stay in place under heavy loads and during extended periods of use.

One of its key features is extreme pressure (EP) protection, which minimizes wear and tear on the coupling surface even under high mechanical stress. It also provides excellent water resistance, helping to prevent wash-off in wet conditions and ensuring continuous lubrication in all weather. Additionally, it offers outstanding corrosion resistance, protecting the fifth wheel plate from rust, oxidation, and premature damage.

5th wheel grease is usually black or dark in color and is applied in a thick layer to the top plate of the fifth wheel. It may also be used in other heavy-load applications such as trailer kingpins or drawbar eyes.

In summary, 5th wheel grease ensures safe, smooth, and reliable operation of fifth wheel couplings by delivering strong load protection, excellent adherence, and long-lasting lubrication in harsh environments.
