Space-Saving Single Turn Wave Springs | SUNZO Factory

Premium space-saving single turn wave springs manufactured by SUNZO. Engineered with premium materials for high fatigue resistant performance in tight axial spaces.

In precision aerospace avionics, medical diagnostic equipment, and high-speed automotive electric motors, mechanical space is at a premium. As systems become more compact, design engineers face a difficult challenge: maintaining steady axial preload within highly restricted envelopes.

Traditional helical coil springs frequently fail in these tight spaces. Their tall physical height requires large housing cavities, which adds unnecessary weight and increases overall packaging costs. Furthermore, when compressed into tight spaces, standard coils often experience uneven stress distribution, leading to rapid force decay and early structural failure.

As a premier, globally recognized high-tech manufacturer of high-performance elastic components, Jiangsu Sunzo Elastic Technology Co., Ltd. (SUNZO) engineers the definitive solution: Space-Saving Single Turn Wave Springs. Manufactured using advanced flat-wire winding technologies, our wave-form elastic components replace bulky conventional coil designs, ensuring constant, predictable linear force while minimizing structural footprints.

To satisfy the strict technical mandates of global OEM procurement networks, Sunzo has developed a specialized manufacturing framework focused on extreme space optimization and structural durability:

Traditional wave forming can introduce micro-scratches and uneven stress concentrations along the crests and troughs of the wave geometry. Sunzo prevents this by utilizing advanced logarithmic winding technology. This computer-controlled process applies a smooth logarithmic curve to the wave profiles. By distributing mechanical loads evenly across the flat-wire cross-section, this process completely eliminates sharp stress concentration points.

We source high-purity, vacuum-degassed flat wire to ensure predictable load performance. Our material inventory is precisely matched to specific environmental demands:

• 65Mn Spring Steel: The definitive choice for high-cycle applications, offering excellent fatigue thresholds.

• SUS304 & SUS316 Stainless Steel: Selected for medical and marine environments to provide complete oxidation defense.

• 1074 High-Carbon Steel: Provides a highly reliable, cost-sensitive option for standard industrial setups.

• Specialty Inconel Alloys: Engineered for extreme thermal zones, maintaining elastic profiles up to 650°C.

This specialized manufacturing approach enables our Single Turn Wave Springs to deliver critical structural advantages:

• Guaranteed 50% Space-Saving: By utilizing flat wire instead of round wire, our wave design reduces the required axial cavity height by up to 50% compared to regular coil springs, while maintaining identical force ratings.

• Excellent Fatigue Resistant Integrity: The uniform stress distribution achieved through logarithmic coiling ensures our springs endure over 1,000,000 continuous compression cycles without experiencing force decay or height loss.

• 30% Structural Weight Reduction: The compact flat-wire design strips away excess dead weight, helping global manufacturers achieve critical lightweight targets in advanced assemblies.

Sunzo’s single-turn wave springs are optimized for precise, low-to-medium load requirements, offering clear mechanical advantages over conventional springs:

• Predictable Small Load Regulation: Calibrated for precise small load requirements ranging from 5N to 500N, delivering minimal deformation tolerance and stable spring rates.

• Perfect Bearing Preload Alignment: Provides smooth, concentric axial tension directly against bearing outer rings. This steady pressure eliminates micro-clearances, minimizes operational noise, and protects high-speed rotating shafts from rotational slop.

Every Sunzo production batch is traceable and backed by certified material testing reports, ensuring seamless compliance across global supply chains:

To protect our high-strength spring steels against harsh environmental wear, Sunzo applies advanced, industrial-grade protective coatings:

• Automated Phosphating: Generates a dense, oil-retaining crystalline layer that provides 500+ hours of salt spray resistance, making it ideal for enclosed automotive gearboxes.

• Mechanical Zinc Plating: Deposits a uniform protective zinc layer without introducing atomic hydrogen, completely eliminating the risk of hydrogen embrittlement in high-tensile steels.

• Dacromet Coating: Provides a thin, non-electrolytic zinc and aluminum flake finish that delivers exceptional thermal stability and fluid resistance in heavy industrial machinery.
