●  Specifications: Unless otherwise specified, spring diameter refers to the outer diameter (OD). The inner diameter can be calculated using the formula: Inner Diameter = Outer Diameter - (2 × Wire Diameter).

●  Pack Quantity: 10 Pcs.

●  High Elasticity and High Strength: Manufactured using professional-grade spring steel, its core advantage lies in its extremely high elastic limit and fatigue strength. Through a special heat treatment process, it possesses excellent impact resistance and relaxation resistance, maintaining shape and performance stability even under long-term, high-frequency reciprocating motion, resulting in an extremely long service life.

●  Versatile Functions: With its excellent energy storage and release efficiency, it effectively buffers impacts, absorbs vibrations, and provides reliable tensile force. As a connecting component, it provides durable and stable tension.

●  Wide Applications: Designed for demanding applications, it is widely used in industrial machinery, automotive parts, precision instruments, and heavy equipment. It is also suitable for household applications requiring high load-bearing capacity, such as garage doors and heavy furniture.
