Since 2006
The 4140 Honed Tube undergoes a meticulous production process to ensure smooth internal surfaces, precise tolerances, and enhanced durability. The key production steps include:
High-quality 4140 steel is sourced and inspected for chemical composition and mechanical properties.
The steel tubes are cold-drawn to improve surface finish, dimensional accuracy, and mechanical strength.
Advanced honing machines are used to achieve smooth bore surfaces (Ra ≤ 0.2 µm) and precise diameter tolerances (H8~H10). This process reduces friction and extends the lifespan of hydraulic components.
Precision straightening machines ensure tube straightness within ≤0.2 mm per 1000 mm.
Depending on client requirements, tubes can be stress-relieved to improve dimensional stability.
Each tube is inspected for bore finish, roundness, straightness, and diameter consistency.
Tubes are carefully packaged to avoid damage during transport and stored in our inventory for quick dispatch.
EASTAI’s 4140 Honed Tube meets global quality standards. Our certifications include:
Every honed tube is traceable and comes with a detailed inspection report, ensuring consistent quality for distributors and engineering companies.
