Advantages of Mercedes Benz Crankshaft
01
High-strength materials and precision engineering
Crankshaft is crafted from high-grade forged steel, designed to withstand the intense forces generated by the 12.8-liter engine’s 510 horsepower and 2,500 nm of torque. Its robust construction ensures resistance to fatigue, cracking, and wear, even under continuous high-load operation.
02
Optimized design for fuel efficiency
Fuel efficiency is a top priority for fleet operators, given the high cost of diesel and the need to reduce operating expenses. The crankshaft’s balanced design reduces frictional losses, optimizing engine efficiency. Combined with the engine’s advanced common-rail injection system, the crankshaft helps achieve up to 5% better fuel economy compared to previous models.
03
Durability for long-haul performance
Long-haul trucks in often cover thousands of kilometers weekly, putting significant stress on engine components.

Features of Mercedes Benz Crankshaft
We use a 1600-ton press to forge each OM355 crankshaft from 40Cr bar stock, then finish machining and balancing it on advanced CNC equipment. The denser grain flow structure can withstand the 17.5:1 compression ratio of the OM355 engine without the bending issues that arise in cast or low-grade alternatives during the mid-to-late stages. Fewer failures mean your L-series fleet can achieve more billable hours-at a reasonable price.
Achieves roundness ≤0.005 mm and surface roughness Ra ≤0.4 μm. Enhances lubrication film stability, reducing oil consumption and startup wear. Works in synergy with dynamic balancing for optimal performance.
Application of Mercedes Benz Crankshaft
The application of a Mercedes-Benz crankshaft is to convert the reciprocating motion of the pistons into rotational motion, which powers the vehicle. This rotational power is transmitted to the wheels to move the vehicle, and the crankshaft also balances the engine's forces.
