Space-Saving Compact Assemblies & Mechanical Seals

Compact Multi Turn Wave Spring for High-Performance Mechanical Seals

In modern mechanical engineering, the trend toward miniaturization requires components that can deliver high performance within highly restricted spaces. Jiangsu Sanzhong Elastic Technology Co., Ltd. provides an engineered solution to this design challenge: the precision-manufactured Multi Turn Wave Spring. Compared to standard helical coil springs, our multi-turn flat-wire wave springs reduce the required axial space by up to 50% while delivering the same force and deflection characteristics. This space-saving design allows engineers to reduce the size, weight, and material costs of their overall assemblies.

AXIAL SPACE COMPARISON: COIL VS. WAVE

Key Advantage: Achieves identical spring force (F) and deflection (s) at half the operating height, reducing assembly weight.

Our multi-turn wave springs are manufactured using a continuous winding process from a single strand of pre-tempered flat wire. This eliminates the structural stress points found in stamped alternatives and provides uniform crest-to-crest contact across the entire spring surface. The result is a consistent, linear spring rate that is ideal for face-sliding components, such as mechanical seals, where precise axial pressure is critical to maintaining a liquid-tight barrier.

Target Client Applications

Industrial Mechanical Seals: Installed in rotating pumps, mixers, and compressors to apply uniform axial tension on carbon or ceramic sealing faces.
Compact Electric Motors: Used to apply constant axial preloads to motor bearings, reducing operational noise and shaft play.
Automotive Powertrain Modules: Integrated into compact clutch packs and transmission gear assemblies where axial space is restricted.

Technical Specifications & Product Parameters

Available Materials: Carbon Steel (SAE 1070-1090), Stainless Steel (SUS302, SUS316, 17-7PH / DIN 1.4568), and Superalloys (Inconel X-750)
Wire Profile: Precision flat wire with radiused edges to prevent internal wear and scratching of housing walls
Outer Diameter (OD) Scope: Standard sizes ranging from 8.0 mm up to 500.0 mm; custom sizes developed promptly
Turn Configuration: Available in crest-to-crest alignments with either plain ends or shim ends for flat contact distribution
Load Accuracy: Tolerances maintained within ±10% through rigorous automated inline spring-rate testing
