Solution

Precision-engineered for optimal performance, our Windshield Wiper Arm Springs are crafted with high-quality materials and advanced galvanization for superior corrosion resistance. These springs offer customizable tension and dimensions to ensure a perfect fit for various vehicle models, providing consistent and reliable wiper blade pressure. Ideal for automotive repairs or upgrades, they deliver enhanced durability, smooth operation, and long-lasting performance in all weather conditions. Trusted by professionals, these high-precision springs ensure your windshield wipers function flawlessly.

Features

1. Spring Force: Typically exerts 8-12 N (Newtons) of constant pressure to maintain consistent blade-to-glass contact, with premium models reaching 14 N for heavy-duty applications.

2. Material Composition: Manufactured from high-carbon steel (SAE 1070-1090) or stainless steel (Grade 304/316), with tensile strength ranging from 1,200-1,500 MPa for corrosion resistance.

3. Temperature Tolerance: Operates effectively between -40°C to +85°C (-40°F to +185°F), with special alloys maintaining elasticity up to 120°C in extreme climates.

4. Fatigue Life: Engineered for 500,000+ compression cycles without significant force degradation (tested per SAE J903 standards).

5. Dimensional Precision: Coil diameter maintains ±0.2mm tolerance, with free length accuracy within ±1.5% of nominal measurement (typically 80-120mm depending on vehicle model).

6. Surface Treatment: Features zinc plating (5-8μm thickness) or powder coating (50-70μm) for salt spray resistance exceeding 500 hours (ASTM B117 testing).

Applications

1. Automotive Windshield Wipers: The primary application of windshield wiper arm springs is in automotive wiper systems. These springs ensure consistent pressure between the wiper blade and the windshield, enabling effective clearing of rain, snow, or debris. They are critical for maintaining visibility and safety in passenger cars, trucks, and commercial vehicles.

2. Marine Vessels: Wiper arm springs are used in marine applications to keep boat and ship windshields clear of water spray, salt, and other obstructions. Their corrosion-resistant variants are essential for withstanding harsh maritime environments.

3. Aviation Industry: Aircraft windshields require reliable wiper systems equipped with durable springs to ensure visibility during takeoff, landing, and adverse weather conditions. These springs must meet stringent aerospace standards for performance and reliability.

4. Railway and Public Transport: Trains, trams, and buses use wiper arm springs to maintain clear windows for drivers and passengers. These springs must endure vibrations and long-term usage while providing consistent wiping performance.

5. Industrial Machinery: Some heavy-duty machinery and equipment feature wiper systems with reinforced springs to remove dust, grease, or liquids from viewing panels, ensuring operational safety and clarity.

6. Agricultural Vehicles: Tractors and harvesters often operate in dusty or muddy conditions, requiring robust wiper arm springs to maintain visibility on cabin windows and protective shields.

FAQ

Q: What is the purpose of a windshield wiper arm spring?

A: The windshield wiper arm spring applies pressure to keep the wiper blade firmly against the windshield for effective cleaning.

Q: How do I know if my wiper arm spring is failing?

A: Signs include streaks, skipping, or the wiper lifting off the windshield during use.

Q: Can I replace just the wiper arm spring?

A: In most cases, yes. However, some designs require replacing the entire wiper arm assembly.

Q: What causes a windshield wiper spring to wear out?

A: Exposure to weather, corrosion, and repeated stress from use can weaken the spring over time.

Q: Are wiper arm springs universal?

A: No, springs vary by vehicle make and model. Always check compatibility before purchasing.
