Import Belleville Disc Springs And Washers — Buy in Bulk from Supplier in China

Belleville disc springs and washers from Optimum Spring China comply with DIN 2092 and DIN 2093 standards, offering a conical design that delivers consistent load over a wide deflection range. These components are engineered for applications requiring reliable spring action in confined spaces, such as automotive suspensions, aerospace assemblies, and heavy machinery. The supplier’s factory in Dayi Town, Yangzhou, Jiangsu, produces these parts with a focus on durability under static and dynamic loads.

The springs are manufactured from alloy steel or stainless steel, providing fatigue resistance and longevity in harsh operating conditions. Typical material grades include 51CrV4 for high-stress applications and AISI 301 for corrosion resistance, with surface treatments like zinc plating or phosphating available as standard. Washers are precision-machined to match the disc spring dimensions, ensuring proper load distribution and alignment in assemblies.

These components are used in bolted joints, valve assemblies, and vibration damping systems where space efficiency and load consistency are critical. Buyers typically source them in bulk for industrial equipment, with packaging options including plastic bags, cartons, or palletised crates for export. Confirm trade terms such as FOB or CIF, lead times, and MOQ directly with Optimum Spring China, as these are not specified in the listing.
