Import Coil Spring — Buy in Bulk from Supplier in China

These are compression coil springs designed for industrial machinery and equipment, offered with wire diameters from 0.1 to 30 mm and outside diameters from 100 to 800 mm. The supplier provides custom sizing to match specific project requirements, ensuring dimensional compatibility with diverse applications. The springs are manufactured using premium-grade steel alloys, selected for their load-bearing capacity and resistance to deformation under cyclic stress.

The material composition typically includes music wire, oil-tempered wire, or stainless steel grades such as AISI 302/304, chosen for their tensile strength and fatigue resistance. Surface treatments like zinc plating or phosphate coating are standard for corrosion protection in harsh environments. The springs are engineered to meet typical industry tolerances for diameter, pitch, and free length, with deviations held within ±2% for critical dimensions. These parameters are critical for applications in automotive suspensions, valve mechanisms, and industrial presses.

Primary buyers include manufacturers in the automotive, construction, and machinery sectors, where these springs serve as energy storage and shock absorption components. The supplier supports bulk shipments with secure packaging to prevent deformation during transit. Buyers should confirm Incoterms such as CIF or FOB, as well as payment terms like L/C, to align with their logistics and procurement workflows. The springs are suitable for integration into assemblies requiring precise load-deflection characteristics.
