OEM High Quality Forged Steel Motorcycle Crankshaft for Engine Parts

Product Description

OEM High Quality Forged Steel Engine Crankshaft for Auto Car and Truck Diesel Engine Parts

Product Description

Our factory supplies engine crankshafts, which are crucial automatic components for automotive diesel engines. The products have high processing accuracy, are resistant to impact, wear-resistant and durable, ensuring the smooth operation of the engine. We strictly control the processing and inspection procedures, maintaining stable quality. We support bulk supply and can meet various purchasing requirements. We welcome customers to inquire and place orders.

A motorcycle crankshaft is the core component of an engine, responsible for converting the reciprocating motion of the piston into rotational motion to drive the transmission system. Our crankshafts are manufactured using high-precision forging and machining processes to ensure perfect balance and durability under high RPMs.

Key Features & Benefits

• High-Strength Material: Manufactured from forged 20CrMnTi or 40Cr alloy steel, offering superior tensile strength and resistance to torsion and wear.

• Precision Machining: CNC machined to achieve tight tolerances (within 0.01mm) for perfect fitment and reduced friction.

• Dynamic Balancing: 100% dynamically tested to minimize vibration, ensuring smooth engine operation even at high speeds.

• Surface Hardening: Treated with nitriding or shot blasting to enhance surface hardness and fatigue life.

• Direct Replacement: Designed to meet or exceed OEM specifications for bolt-on installation without modifications.

Common Crankshaft Materials

• Steel: Most high-performance and heavy-duty crankshafts are made from steel because it offers a balance of strength, durability, and weight. Steel crankshafts are commonly forged or cast.

• Iron: Cast iron is another common material used for crankshafts, especially in standard passenger vehicles. It's less expensive but generally not as strong as steel.

• Alloyed Steel: This is a steel alloy (such as chromium or nickel) used for making high-performance crankshafts. These materials provide enhanced strength and heat resistance.
  
  

  Applications of Crankshafts

• Automobiles: Crankshafts are found in virtually all internal combustion engines, from small four-cylinder engines to large V8 or V12 engines.

• Motorcycles: The crankshaft in motorcycles is similar in function to automotive engines, though smaller and lighter.

• Aircraft Engines: Aircraft engines often feature larger, more robust crankshafts due to the higher power demands and reliability requirements.

• Marine Engines: Crankshafts in marine engines are designed to withstand harsh conditions, such as saltwater exposure, and handle large torque loads.

• Industrial Machinery: Crankshafts also appear in machinery like compressors, pumps, and generators, where they convert power for various mechanical systems.

Quality Control Process

We implement a strict quality control system at every stage of production to ensure reliability:

1. Incoming Inspection: Raw material chemical composition analysis.

2. In-Process Inspection: Dimensional checks during forging and machining.

3. Dynamic Balancing Test: Ensures rotational stability.

4. Final Inspection: 100% visual and functional check before packaging.

Packaging & Delivery

• Inner Packaging: Each crankshaft is oiled and wrapped in anti-rust paper, then sealed in a poly bag.

• Outer Packaging: Standard strong export carton or plywood case palletized for sea freight.

• Lead Time: 7-15 days for stock items; 20-30 days for bulk orders (depending on quantity).
