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
