Import Din137 Wave Spring Washer — Buy in Bulk from Supplier in China

The DIN137 Wave Spring Washer is a precision-engineered component designed to provide axial load distribution and vibration damping in mechanical assemblies. It is manufactured to DIN 137 standards with material options including 65Mn spring steel, SS304, and SS316 stainless steel, each selected for tensile strength and fatigue resistance. Dimensions follow standard DIN profiles with inner diameters ranging from 5mm to 100mm and thicknesses from 0.5mm to 3.0mm, depending on the load class.

These washers are typically produced with surface treatments such as zinc plating, Dacromet, Geomet, or black oxide to enhance corrosion resistance. The choice of material and finish depends on environmental exposure: SS316 is preferred for wet or marine conditions, while 65Mn is common in dry, high-cycle applications. The wave profile is cold-formed to ensure consistent spring rate and load deflection characteristics, meeting industry norms for repeatable performance under dynamic stress.

End users include automotive suspension systems, aerospace actuator assemblies, and industrial machinery requiring compact, high-load spring elements. Buyers typically source these in batches of 1,000 to 50,000 pieces, with packaging in poly bags inside cartons or on plastic spools. Trade terms are commonly FOB Shanghai or CIF to major ports. Confirm material certification and dimensional tolerance reports before shipment.
