What are Springs?
Springs are mechanical components designed to store and release energy through elastic deformation. They come in various types and materials tailored for specific applications across industries like automotive, aerospace, and manufacturing.
Types of Springs
Springs can be categorized into several types: compression, extension, torsion, disc (Belleville), wave, gas, and constant force springs. Compression springs are used to resist applied compressive forces. Extension springs provide resistance against tensile forces. Torsion springs work by twisting around their axis. Disc or Belleville springs offer high load capacities in thin profiles. Wave springs fit compact spaces with multiple coils. Gas springs use compressed gas for smooth motion and force regulation. Constant force springs supply a consistent pulling or pushing force.
Materials and Specifications
Springs are typically made from music wire, stainless steel (e.g., A2-70), phosphor bronze, Inconel, titanium, and carbon steel (EN8). Each material has unique properties such as corrosion resistance, strength, and durability. Standards like BS 1726 for cylindrical springs, EN 13906 for design calculations, and ISO 10243 for die springs ensure uniform quality across the industry.
How to Choose the Right Springs
Choosing the right spring involves considering factors such as load requirements, space constraints, environmental conditions, and durability. Compression springs need precise coil geometry and material strength to handle compressive loads efficiently. Extension springs must withstand tensile forces without deforming under stress. Torsion springs require high torque resistance for rotational applications. Material grades like A2-70 stainless steel or EN8 carbon steel ensure longevity in corrosive environments.
UK Suppliers
MLC lists verified suppliers from Companies House, ensuring that engineers and procurement managers can find reliable sources of Springs.
