Product Description

Totem Custom Heavy Duty  High Hardness High Quality Big Crankshaft
A precision-engineered heavy-duty step shaft designed for demanding industrial applications, featuring customizable diameters and lengths to meet specific mechanical transmission requirements.
Specification
Product 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.
Precision Quad Crankshaft – Heavy-Duty 4-Axis Engine Shaft for Industrial Machinery
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).
Precision Quad Crankshaft – Heavy-Duty 4-Axis Engine Shaft for Industrial Machinery
Key Specifications:
Material Science
Core 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 Excellence
Processes: Closed-die forging → CNC machining → Dynamic balancing (ISO 1940-1 G6.3).
Tolerances: Journal diameter ±0.01mm, surface roughness Ra ≤0.4μm.
Mechanical Performance
Load Capacity: Sustains peak pressures up to 250 bar (diesel engines).
Fatigue Life: Minimum 1 million cycles under ASTM E606 strain-controlled testing.
Precision Quad Crankshaft – Heavy-Duty 4-Axis Engine Shaft for Industrial Machinery
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."*

Heavy Duty Crankshaft Gravity Testing
Definition & 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.
