seamless world

Product catalog summary

Overview: The document describes ultra-thin wall seamless metal sleeves, highlighting their seamless construction, elasticity, and flexibility. These sleeves are made using a precise process that ensures stability and resistance to deforming stress. They are constructed from high tensile metals, offering robustness and excellent fatigue strength. Surface treatments such as mirror finish and surface hardening are available.

Applications: The sleeves are suitable for sheet-forming, printer metal belts, drums, and flexible rolls.

Features: The sleeves are characterized by their seamless and joint-free design, smooth surface, and remarkable elasticity. They are ultra-thin, lightweight, and flexible, made from high tensile metals with excellent fatigue strength.

Types: There are two main types of sleeves: EF Type (Electro-Forming) and FF Type (Flow-Forming).

Materials: The sleeves can be made from various materials including SUS304 stainless steel, nickel alloy, copper, clad metals (two-layer and three-layer), titanium, and special metals.

Specifications:

EF Type: Tensile strength of approximately 1,600 N/mm², hardness of 450-500 Hv, roughness of 0.5s, Young's modulus of 200 kN/mm², fatigue strength of 800 N/mm², and heat resistance up to 400°C.
FF Type: Tensile strength of approximately 1,200 N/mm², hardness of 450-500 Hv, roughness of 0.3s, Young's modulus of 200 kN/mm², fatigue strength of 400 N/mm², and heat resistance up to 150°C.

Production Sizes:

EF Type: Large (diameter ≤ 500 mm, thickness 0.2-0.5 mm, length up to 2500 mm), Medium (diameter ≤ 300 mm, thickness 0.3-0.5 mm, length up to 2500 mm).
FF Type: Large (diameter ≤ 1000 mm, thickness 0.1-1.0 mm, length up to 2000 mm), Medium (diameter ≤ 320 mm, thickness 0.1-0.4 mm, length up to 500 mm), Small (diameter ≤ 150 mm, thickness 0.03-0.3 mm, length up to 400 mm).
