The trunnion on a semi truck is a type of bearing that helps to reduce friction and provide stability when the truck is in motion. It is located between the wheels and the axle, and consists of two metal plates held together with bolts. The trunnion acts as a pivot point between the wheel and axle, allowing the wheel to rotate freely while providing support for the axle. This reduces wear on the wheel bearings, as well as providing greater maneuverability.
The trunnion can be made from various materials, such as steel or aluminum, depending on its application. Generally, steel trunnions are used for heavy-duty applications such as logging trucks, while aluminum trunnions are used for lighter-duty applications such as passenger vehicles. The trunnion design also varies based on its application; some designs include extra features such as lubrication ports or grease fittings.
In addition to reducing friction and providing stability, the trunnion also helps to absorb shock from bumps in the road.
This helps to keep the truck stable when driving over rough terrain. The trunnion also provides an additional point of contact between the wheel and axle which can help reduce vibration when driving at high speeds.
The trunnion is an essential part of a semi truck’s design and plays an important role in keeping it running smoothly. Without it, the truck would not be able to maneuver properly or handle bumps in the road without causing damage to its components. As such, it is important that it is properly maintained and inspected regularly for any signs of wear or damage.
Conclusion:
The trunnion on a semi truck is a vital component that helps reduce friction and provide stability when in motion. It is made from various materials depending on its application, and helps absorb shock from bumps in the road while providing an additional point of contact between wheels and axles. Proper maintenance of this component is essential for ensuring that semi trucks remain safe on roads and highways.

A semi truck, also known as a semi-trailer truck, tractor-trailer or transport truck, is a large commercial vehicle that is used to haul freight from one location to another. Semi trucks are typically used for long-haul trips between cities and have the capacity to carry up to 80,000 pounds of cargo at a time. As such, they are essential for transporting goods across the country.
A semi truck is an integral part of the transportation industry due to its ability to move large amounts of goods in a single trip. In order to ensure that these trucks remain efficient and safe, they have to be equipped with a variety of components and systems. One such component is the SCR, or Selective Catalytic Reduction system.
Towing a semi truck is no easy feat. The sheer size, weight and complexity of a semi require special skills and expertise to tow it properly. The right equipment, know-how and experience can make the job easier, but it’s still a daunting task.
