Features

1. High-Cycle Durability: Engineered for 20,000+ operation cycles at full load capacity (tested per SAE J1123 standards), these springs maintain ≤5% torque loss after accelerated lifespan testing. Premium alloy steel (ASTM A228/A401) ensures fatigue resistance even under -40°F to 250°F temperature extremes.

2. Precision Torque Output: Available in 12-350 in-lb torque ranges (±5% tolerance), with customizable wind angles (180°-360°) to match specific counterbalance requirements. Computer-controlled tempering achieves consistent 45-52 HRC hardness for uniform force distribution.

3. Corrosion Protection: Triple-layer defense system featuring zinc electroplating (8-12μm), epoxy powder coating (60-80μm), and optional salt-spray resistant finishes passing 500+ hours in ASTM B117 testing. Ideal for marine and winter road salt environments.

4. Safety-Enhanced Design: Incorporates positive-lock end hooks with 20% greater bend radius than industry standard (per DIN 2098 Grade 2), preventing sudden unwinding. Load-tested to 150% of rated capacity without permanent deformation.

5. Weight Optimization: Hollow-core variants reduce mass by 30-40% (typical weight 1.2-4.8 lbs depending on wire diameter 0.25"-0.75") while maintaining equivalent torque values through advanced helical geometry calculations.

6. Vibration Damping: Proprietary silicon-carbide shot peening creates compressive surface stresses up to -650 MPa, reducing harmonic oscillations by 60% compared to conventional springs when measured at 50-2000 Hz frequency ranges.

Applications

1. Automotive Industry: Tailgate Torsion Springs are essential in vehicles with liftgates or hatchbacks, providing smooth opening and closing mechanisms. They ensure controlled motion, reducing wear on hinges and improving user safety. Commonly found in SUVs, trucks, and vans, these springs enhance durability and convenience.

2. Industrial Machinery: In heavy-duty equipment like conveyor systems or loading docks, torsion springs assist in managing heavy loads. They help counterbalance doors or panels, reducing manual effort and preventing sudden drops, which is critical for workplace safety.

3. Furniture Manufacturing: Used in recliners, folding beds, or cabinet doors, these springs enable effortless movement and space-saving designs. They provide consistent tension, ensuring longevity and smooth operation in home and office furniture.

4. Aerospace Applications: Tailgate Torsion Springs are employed in aircraft cargo doors or access panels, where precision and reliability are paramount. Their ability to withstand extreme temperatures and stress makes them ideal for aviation environments.

5. Medical Equipment: In hospital beds, stretchers, or surgical tables, these springs facilitate adjustable positioning. Their silent and smooth operation ensures patient comfort and ease of use for healthcare professionals.

6. Agricultural Machinery: Farm equipment like tractor trailers or grain hoppers utilize torsion springs to manage heavy gates or covers. They withstand harsh outdoor conditions while maintaining performance over time.

FAQ

1. What is a Tailgate Torsion Spring?
 A tailgate torsion spring is a helical spring that provides torque to assist in lifting and lowering truck tailgates, reducing manual effort.

2. How does a Tailgate Torsion Spring work?
 It stores mechanical energy when twisted (torque) and releases it to counterbalance the tailgate's weight, ensuring smooth operation.

3. What are common signs of a failing Tailgate Torsion Spring?
 Symptoms include difficulty lifting the tailgate, uneven movement, or a sudden "drop" when releasing the tailgate.

4. Can I replace a Tailgate Torsion Spring myself?
 Yes, but caution is required due to high tension. Use safety gloves and follow the manufacturer's installation guide.

5. What materials are Tailgate Torsion Springs made of?
 Most are crafted from high-carbon steel or alloy steel for durability and resistance to fatigue.

6. How long do Tailgate Torsion Springs typically last?
 Lifespan varies with usage, but they generally last 5–10 years before needing replacement.
