An interlaced wave spring is a type of multi-turn wave spring in which two or more individual wave springs are wound together (interlaced) simultaneously to form a single, unified spring structure.

?? Key Characteristics:

• Tightly integrated turns: Unlike stacked springs, interlaced wave springs have overlapping waves formed during the coiling process, not assembled afterward.

• Higher load capacity: They provide greater spring force than a single-layer wave spring due to the multiple intertwined layers.

• Compact design: Delivers high load in a relatively short working height, ideal for space-limited applications.

• Better stability: Compared to stacked single-layer springs, interlaced designs eliminate alignment issues and reduce shifting under dynamic loads.

?? Typical Applications:

• Bearing preload in automotive and aerospace

• High-load connectors

• Mechanical seals

• Tight axial space assemblies requiring high spring force

• Effectively provides increased loading capacity and greater fatigue resistance
• Alternative to peaks versus troughs when higher loads are needed
• Substitute to a Nested Spirawave when higher free height or delection is needed
