A cast crankshaft is a crucial component in an internal combustion engine, designed to convert the linear motion of the pistons into rotational motion that powers the vehicle. Typically made from cast iron or forged steel, these crankshafts are engineered to withstand high levels of stress and wear during operation. Their design often includes counterweights to balance the engine and reduce vibrations.
| Material | Cast iron or forged steel |
| Standard sizes | Various lengths and diameters depending on engine design |
| Weight | Typically ranges from 10 to 50 kg |
| Surface finish | Machined to specific tolerances for optimal performance |
| Heat treatment | Often heat-treated for increased strength and durability |
When selecting a cast crankshaft, buyers should consider the specific engine type and application to ensure compatibility. It's important to specify the required material grade, any necessary heat treatments, and tolerances for machining. Additionally, buyers should inquire about certifications that may be relevant for their industry, as well as the quantity needed for production runs.
