DIN CK45 SAE 1045 Cylinder Hollow Piston Rod

DIN CK45 / SAE 1045 Hollow Piston Rod is a type of precision-engineered hollow steel rod commonly used in hydraulic and pneumatic systems. These rods are specifically designed to function as critical components of hydraulic cylinders, offering a balance of strength, toughness, and machinability.

Material

Our chrome-plated steel tubes are manufactured from premium-quality carbon steel, available as cold-drawn seamless tubes or hollow bars. The steel grades we offer include St 52.3, St 37.4, E355, SAE 1020, SAE 1026, SAE 4041, and SAE 1045, ensuring reliability and superior performance across various applications.

Dimensions

O.D: 15 mm to 609 mm, W.T: 1 mm to 40 mm.

Tolerance

O.D tolerance options of ISO f7, f8, and others to meet customers' specific requirements.

Key Features:

Material Grades:

• DIN CK45: Medium carbon steel as per DIN standards.
• SAE 1045: Equivalent medium carbon steel in SAE standards.
  Both materials are known for their high strength, wear resistance, and good machinability.

Hollow Design:

• Reduced weight compared to solid rods, making it ideal for applications requiring efficiency and lighter components.
• Allows internal fluid passage when needed, adding versatility.

Surface Treatment:

• Typically hard chrome-plated to enhance surface hardness, corrosion resistance, and reduce wear.
• Achieves a smooth finish (Ra ≤ 0.2-0.4 μm) for effective sealing and reduced friction.

Mechanical Properties:

• High tensile strength: ~600-700 MPa (depending on the heat treatment).
• Good ductility and impact resistance.

Dimensional Precision:

• Accurate outer and inner diameter tolerances ensure compatibility with cylinder seals and components.

Chemical Composition (Typical for CK45/SAE 1045):

Applications:

1. Hydraulic Cylinders: As the primary component for transmitting force within hydraulic systems.
2. Pneumatic Cylinders: Used in air-powered systems where reduced weight is advantageous.
3. Automotive and Aerospace: For lighter yet strong mechanical components.
4. Construction Machinery and Heavy Equipment: To handle high loads and stresses.
5. Industrial Equipment: For machinery that requires high-performance motion systems.

Advantages:

• Weight Reduction: The hollow structure provides significant weight savings without compromising strength.
• Corrosion Resistance: Chrome plating protects against rust and wear, especially in harsh environments.
• Cost Efficiency: Reduces material costs while maintaining structural integrity.
• Customizability: Can be tailored to specific dimensions and requirements.

DIN CK45 / SAE 1045 hollow piston rods are ideal for applications demanding durability, precision, and efficiency in hydraulic and pneumatic systems.
