Triangle PTO Shaft Tube – Carbon Steel Special-Shaped Pipe for Agricultural Drive Shaft

Material

This is a special‑shaped (triangular or “lemon”) seamless carbon steel tube, specifically designed for use as a PTO (Power Take‑Off) shaft tube in agricultural drive systems. Materials include carbon steel grades such as ST52, E235, E355 (according to EN 10305‑1), as well as SAE grades 1010, 1020, 1040, Q345B, and Q355B. These are cold‑drawn and optionally cold‑finished, delivering a durable tube for heavy operational use

Specifications

• Shape: Triangular or "lemon" profile, suited for telescoping drive shaft systems.

• Wall Thickness: Typically ranging from approximately 0.5 mm to 50 mm Length: Customizable; common offerings include 2–12 m, 6 m, 12 m, or per customer requirement

• Hardness: Certain products specify hardness ranges of 40–55 HRC

• MOQ & Delivery:

  • Minimum order quantities vary by supplier (as low as 1 ton to 5 tons); delivery lead times range from roughly 8–60 days

Chemical Composition (Selected Comparison of Five Similar Grades)

Source: Chemical composition tables from suppliers using EN 10305‑1 and GB/T 3639 standards

Mechanical Properties (Example: ST52 Cold-Drawn)

• Tensile Strength: ≤ 490 MPa

• Hardness: ≥ 65 HB (Brinell hardness) after cold drawing and finishing

(Note: Specific mechanical properties vary depending on steel grade and heat‑treatment or finishing method.)

Key Characteristics

• Durability: High-strength carbon steel provides excellent wear and load resistance.

• Precision: Cold-drawn finishing ensures tight dimensional tolerances and smooth surfaces.

• Customizability: Various grades, shapes, lengths, wall thicknesses, and surface treatments (e.g., galvanizing, painting, oiling) are available per requirements

• Compliance: Manufactured to common international standards such as EN 10305‑1, DIN, GB/T, ISO, API, and ISO 9001 certified in many cases

Applicable Standards

• EN 10305‑1 (cold-finished carbon steel tubes)

• DIN 2391 / GB/T 3639

• Supplier certifications such as ISO 9001, API, etc.

Application Areas

Primary Field: Agricultural machinery, specifically telescopic PTO drive shafts used to transmit power from tractors to implements.

Specific Applications Include:

• Rotavators (rotary tillers)

• Mowers

• Balers

• Tillers

• Various implements requiring flexible, high-torque torque transmission
