Sheath Body: Diameter Range 10-200 mm, Length Tolerance ±0.5 mm

Component Specifications

Definition

The Sheath Body serves as the main cylindrical or tubular structure in protection sheath assemblies, designed to withstand mechanical stresses, abrasion, and environmental factors while maintaining flexibility and durability. It typically features integrated mounting points, sealing surfaces, and reinforcement structures to ensure proper installation and long-term performance in industrial applications.

Working Principle

The Sheath Body operates on the principle of mechanical containment and environmental isolation. It provides a rigid or semi-rigid enclosure that protects internal components from external impacts, contaminants, and temperature fluctuations while allowing controlled movement and maintaining alignment with connected systems.

Materials

Typically manufactured from engineering-grade polymers (polyurethane, nylon, polyethylene), reinforced composites, or corrosion-resistant metals (stainless steel, aluminum alloys). Material selection depends on application requirements including temperature range (-40°C to +120°C), chemical resistance, and mechanical strength specifications.
