Product DescriptionTotem Custom Heavy Duty High Hardness High Quality Big CrankshaftA precision-engineered heavy-duty step shaft designed for demanding industrial applications, featuring customizable diameters and lengths to meet specific mechanical transmission requirements.SpecificationProduct Overview:A Heavy Duty Crankshaft is a precision-engineered mechanical component designed to convert reciprocating motion into rotational motion in high-stress environments. Manufactured from high-strength alloy steel or forged steel, it ensures exceptional durability, fatigue resistance, and load-bearing capacity for industrial engines and machinery.Key Features:Material: Forged steel or alloy steel (e.g., 42CrMo, SAE 4340) with heat treatment (quenching & tempering).Process: CNC machining, dynamic balancing, and surface hardening (induction hardening/nitriding).Applications: Diesel engines, generators, marine propulsion, mining equipment, and heavy construction machinery.Customization: OEM/ODM support for dimensions, counterweights, and journal finishes.Advantages:Extended Service Life – Resists wear under extreme torque and continuous operation.High Load Capacity – Supports large-displacement engines (e.g., 6-cylinder+).Vibration Reduction – Precision-balanced for smooth performance.Compliance & Standards: ISO 9001, ASTM, or industry-specific certifications (e.g., ABS for marine use).Key Specifications:Material ScienceCore Materials: Forged alloy steel (42CrMo4, SAE 4340) or ductile iron (EN-GJS-700-2).Heat Treatment: Induction hardening (HRC 55-60), nitriding, or shot peening for fatigue resistance.Manufacturing ExcellenceProcesses: Closed-die forging → CNC machining → Dynamic balancing (ISO 1940-1 G6.3).Tolerances: Journal diameter ±0.01mm, surface roughness Ra ≤0.4μm.Mechanical PerformanceLoad Capacity: Sustains peak pressures up to 250 bar (diesel engines).Fatigue Life: Minimum 1 million cycles under ASTM E606 strain-controlled testing.Usage Example:*"Our heavy duty crankshafts are widely used in 500–3000kW diesel generators and offshore vessel engines, ensuring reliable power transmission even under 24/7 operation."*Drawings & DimensionsDetailed CAD drawings and dimensional diagrams are available for download here or upon inquiry. Our engineering team can provide tailored designs to meet specific project requirements.Heavy Duty Crankshaft Gravity TestingDefinition & Function:Heavy duty crankshafts are subjected to extremely high dynamic loads in industrial applications, therefore gravity testing is a critical step in ensuring their structural strength, fatigue life, and safety.An industrial heavy-duty crankshaft is a precision-engineered mechanical component that converts the linear motion of pistons into rotational torque in high-power applications. Designed to withstand extreme stress, it serves as the backbone of large combustion engines and heavy machinery.After Sales ServiceStandard Warranty: 6 months.Extended Warranty: Optional coverage up to 12 months.Global Support: 24/7 technical assistance and spare parts supply.Training: On-site or remote operation/maintenance training.Company ProfileSHANGHAI TOTEM MACHINERY CO., LTD.Shanghai Totem Machinery Co., Ltd.
