Their core selling points are reflected in three aspects: First, they store and release energy through elastic deformation, making them suitable for applications such as vibration damping and resetting traction; second, they offer outstanding uniaxial load-bearing characteristics, precisely matching linear tension requirements; and third, they offer a compact structure and flexible installation, making them suitable for space-constrained mechanical devices.
Their performance characteristics encompass four key dimensions: They are constructed from high-carbon steel or stainless steel, ensuring a fatigue life of at least 10^6 cycles; their elastic modulus ranges from 5N/mm to 500N/mm to meet diverse load requirements; their surface galvanizing/phosphating enhances corrosion resistance, allowing them to operate in temperatures ranging from -40°C to 120°C; and their precision rolling process ensures a load tolerance of ±5%, guaranteeing system stability.
Overall, extension springs, with their balanced design of mechanical performance and durability, have become the preferred elastic solution for automation equipment, automotive components, household appliances, and other fields.
