10-12Convolution Flex Bellow D11.5

The 10-12 Convolution Flex Bellow D11.5 (10-12-wave flexible bellows, outer diameter 11.5 mm) is a precision, compact flexible component. Its core advantages include high flexibility, precise displacement compensation, long service life, excellent sealing performance, and weather resistance. It is specifically designed for precision equipment and confined spaces.

I. Structural and Specification Advantages

Optimized 10-12-wave design

Uniform stress distribution ensures fatigue resistance and extended service life (standard ≥ 100,000 cycles).

Ample effective extension/deflection travel accommodates axial, radial, angular, and composite displacements.

The moderate number of corrugations balances flexibility and rigidity: easier to bend and with greater compensation capacity than low-corrugation products; stronger resistance to negative pressure and greater stability than high-corrugation products.

D11.5 Precision Outer Diameter

Standard small-bore design for easy installation and minimal space requirements, suitable for confined spaces and complex wiring/tubing layouts.

Compact and lightweight, suitable for precision instruments, medical devices, semiconductors, and aerospace wiring harnesses/fluid systems.

 

 

 

II. Core Performance Advantages

Exceptional Flexibility and Installation Adaptability

Significantly reduces installation difficulty, minimizes the number of fittings, and lowers the risk of leaks.

Capable of tight-radius bending and repeated expansion/contraction, accommodating complex assemblies and installation tolerances.

High-Precision Sealing (Metal / Polymer Materials)

Fluoropolymers (FEP/PFA): Resistant to severe corrosion, FDA-approved for food/pharmaceutical contact, self-lubricating, and easy to clean.

Metal Materials (304/316L): Helium mass spectrometer leak rate ≤ 1×10⁻⁹ Pa·m³/s; reliable vacuum and high-pressure sealing.

Superior Weather Resistance and Durability

High-grade plastics: -40°C to +150°C; oil-resistant, chemical-resistant, and anti-aging.

Stainless Steel: -200°C to +600°C; resistant to acids, alkalis, seawater, and oxidation; long-term stability in outdoor and harsh environments.

Vibration Damping, Noise Reduction, and Stress Relief

Reduces fluid and mechanical noise, improving system stability and service life.

Effectively absorbs vibrations, impacts, and thermal expansion/contraction, protecting pipes, fittings, and precision components.

High Pressure Resistance and Fatigue Resistance

Resists cracking and failure during repeated expansion/contraction and bending, with extended maintenance intervals.

Thin-walled precision molding: Pressure resistance 0.6–4 MPa (depending on material), balancing flexibility and strength.

III. Typical Application Benefits

Precision Fluid/Pneumatic Lines: Medical equipment, analytical instruments, semiconductors, aerospace hydraulic/pneumatic systems — reliable sealing, excellent flexibility, long service life.

Wire Harness Protection: Automotive, new energy, industrial electronics — resistant to bending, abrasion, and temperature extremes; provides insulation and electromagnetic interference (EMI) protection.

Displacement Compensation: Precision machinery, sensors, valves — compact size, large compensation range, zero backlash, high precision.
