ROCKER ARM

Gross Product


Forged Rocker Arm

The forged rocker arm is a key mechanical component in the valve train of internal combustion engines.
Widely used in heavy trucks, mining equipment, construction machinery, defense vehicles, and public works engines, it transfers the motion from the camshaft to the valves, ensuring optimal air-fuel intake and efficient exhaust gas evacuation.

An iconic component of the forging industry, the rocker arm is made from forged steel alloy, providing exceptional resistance to mechanical and thermal stresses. This durability is critical in large-displacement engines operating under extreme conditions.
Available either as a raw forged blank or a fully machined, ready-to-install part, it meets the strictest requirements of OEMs and industrial vehicle manufacturers.


🔩 Role and Function of the Rocker Arm

  • Transfers camshaft motion to the valves.

  • Ensures precise valve opening and closing.

  • Optimizes combustion and therefore engine performance.

  • Withstands intensive duty cycles.


🚚 Applications

Forged rocker arms are used in:

  • Truck and semi-trailer engines.

  • Construction and earthmoving machinery (excavators, bulldozers, loaders…).

  • Special industrial vehicles (transport, public works, mining operations).


✅ Advantages of a Rocker Arm forged

  • High mechanical strength under repeated loads.

  • Extended lifespan, even under extreme conditions.

  • Dimensional accuracy for optimal engine operation.

  • Superior reliability compared to casting or stamped parts.
