Canted coil spring vs compression spring comparison covering structure, load behavior, fatigue life, EMI shielding performance, and applications to help engineers select the right spring solution.
When selecting a spring for precision mechanical or electrical applications, engineers frequently compare canted coil spring vs compression spring designs. Although both spring types serve to store mechanical energy and provide force, the canted coil spring offers fundamentally different performance characteristics compared to a traditional compression spring.
A Schrägzugfeder is specifically engineered to deliver consistent force, long fatigue life, and excellent electrical conductivity. In contrast, compression springs are widely used for general mechanical purposes but are limited in high-cycle and high-reliability environments. Understanding the difference between a Schrägzugfeder and a compression spring is essential for achieving optimal system performance.
A Schrägzugfeder is a precision spring made from a continuous wire formed into coils that are intentionally angled relative to the spring axis. This angled geometry allows each coil of the Schrägzugfeder to act independently during compression.
The unique structure of a Schrägzugfeder provides several mechanical advantages:
Because of this design, a Schrägzugfeder can maintain a near-constant force over a wide working deflection range.
A properly designed Schrägzugfeder offers:
These features make the Schrägzugfeder ideal for precision and high-reliability applications.
A compression spring is a conventional mechanical spring designed to resist axial compression. Unlike a Schrägzugfeder, a compression spring relies on parallel coils that stack against each other under load.
While a Schrägzugfeder distributes stress evenly across angled coils, a compression spring experiences increasing stress as coils come into contact. This structural difference explains why a Schrägzugfeder performs better in high-cycle applications.
| Merkmal | Canted Coil Feder | Compression Spring |
|---|---|---|
| Geometrie der Spule | Angled | Parallel |
| Stress Distribution | Even | Concentrated |
| Coil Interaction | Independent | Coil stacking |
| Friction | Low | High |
The structural advantages of a Schrägzugfeder directly result in superior mechanical and electrical performance.
One of the most important benefits of a Schrägzugfeder is its ability to maintain consistent force throughout compression. This makes the Schrägzugfeder ideal for applications requiring stable contact pressure.
Compression springs exhibit increasing force as deflection increases. In contrast, a Schrägzugfeder avoids excessive load buildup, protecting mating components and extending system life.
Because each coil in a Schrägzugfeder deflects independently, fatigue stress is significantly reduced. A Schrägzugfeder can withstand millions of cycles without significant performance degradation.
Compression springs experience coil friction and permanent deformation under repeated loads. In applications where long life is critical, a Schrägzugfeder is a far more reliable solution.
A Schrägzugfeder provides continuous conductive contact and uniform pressure, which is essential for effective EMI shielding. For this reason, the Schrägzugfeder is widely used in RF enclosures, connectors, and electronic housings.
Compression springs lack consistent electrical contact and are not designed for EMI shielding. In contrast, a Schrägzugfeder maintains electrical continuity even under vibration.
A Schrägzugfeder can be installed in various groove designs, including rectangular, dovetail, and circular grooves. This flexibility allows the Schrägzugfeder to accommodate misalignment and surface irregularities better than compression springs.
Common applications for a Schrägzugfeder umfassen:
In each case, the Schrägzugfeder outperforms traditional compression springs in reliability and service life.
Although a Schrägzugfeder has a higher initial cost, its long service life and reduced maintenance make it a cost-effective solution over time. For high-reliability systems, a Schrägzugfeder offers superior total cost of ownership.
