The pitch is the distance between adjacent coils, and the number of coils contributes to the spring’s behavior and characteristics. These specifications impact parameters such as spring rate and load distribution.
- Load-Bearing Capacity:
The load-bearing capacity of a spring is the maximum force it can withstand without permanent deformation. This specification is critical for ensuring the spring can handle the loads it will experience in its intended application.
- Spring Rate:
The spring rate, also known as stiffness or constant, indicates the relationship between force and displacement for a spring. It defines how much a spring will compress or extend under a given load.
Springs are made from a variety of materials, such as steel alloys, stainless steel, or specialized materials for specific applications. Material specifications dictate the spring’s mechanical properties, corrosion resistance, and thermal characteristics.
- Surface Finish:
The surface finish of a spring can impact its fatigue life, corrosion resistance, and interaction with other components. Specifications for surface finish ensure that springs meet the desired level of performance and appearance.
