The forged steel crankshaft is the most critical component of the vehicle engine. It bears the force from the connecting rod and converts it into torque, and drives other parts on the engine through the crankshaft output. The forged steel crankshaft of Shandong Liou Import and Export Co., Ltd. adopts the world's top crankshaft processing equipment to ensure that the accuracy of each crankshaft journal size reaches the highest standard. The high-strength and high-hardness journal processing technology prolongs the life of the crankshaft. The rear oil seal of the crankshaft has wear-resistant properties and greatly reduces the degree of wear. The one-time crankshaft finishing technology effectively reduces the curvature of the crankshaft, ensures that the runout of the fourth main journal is less than 0.08mm, and ensures the accuracy of the crankshaft rotation. The material performance of our forged steel crankshaft has reached the higher QT800-3 standard, with a hardness between 48HS and 58HS. It is made of 40Cr steel and has been surface nitrided and arc-edge rolled, providing the product with stronger durability and reliability.
1. Precision machining: Using the world's top crankshaft machining equipment, the dimensional accuracy of each journal reaches the highest standard, effectively reducing the crankshaft bending and ensuring stable performance.
2. High strength and durability: The forged steel material meets the QT800-3 standard, with a hardness between 48HS and 58HS. It undergoes surface nitriding and arc edge rolling treatment to improve durability and reliability.
3. Long life design: The journal is processed with high strength and high hardness, and the rear oil seal of the crankshaft is wear-resistant, which reduces wear and increases life.
4. Precise rotation: Processing technology ensures that the fourth main journal runout is less than 0.08mm, ensuring the accuracy of crankshaft rotation and improving the overall performance of the engine.
5. Quality assurance: We offer a variety of models to choose from, with high-quality packaging and a warranty of up to 3 years or 50,000 kilometers to ensure customer satisfaction.
