Product Overview

Our Custom OEM Stamping Steel Cup Spring Washer is a high-performance conical spring washer engineered for demanding fastening applications. Also known as Belleville washers, disc springs, or conical spring washers, these components feature a cupped/conical shape that compresses under axial load, delivering consistent spring tension and maintaining preload in bolted joints. DIN 6796 cup washers are a type of conical spring washer specifically used in bolt connections that require high pre-tension forces
Core Advantages

• Vibration Resistance – The conical spring design effectively prevents fastener loosening caused by vibration and dynamic loads. In automotive engineering, they are commonly used in engine assemblies, suspension systems, and other critical components where robust performance is non-negotiable. Spring cup washers ensure the reliability and stability of fastened components, reducing the need for frequent adjustments and maintenance.

• Consistent Tension Maintenance – Heat-treated to achieve optimal hardness and fatigue resistance, ensuring reliable preload throughout service life. This capability is particularly beneficial in automotive and aerospace applications, where vibrations can lead to significant failure over time.

• Load Distribution – The conical cup shape distributes force evenly across the bearing surface, protecting connected components from damage and extending assembly lifespan.

• Compact Design – Generates high spring forces in minimal axial space. Their compact design allows them to fit well in tight spaces, making them a preferred choice in compact mechanical systems.

Material & Finish Options

Surface treatments available: zinc plating (standard), plain finish, black oxide, or custom as specified. The raw material used in manufacturing is procured from certified vendors to ensure consistent quality standards.

Technical Specifications

• Standard: DIN 6796 (conical spring washers for bolt connections with high pre-tension requirements), also compliant with DIN 2093 equivalent specifications

• Manufacturing Process: Precision stamping from coil stock, heat-treated (austempering) for consistent hardness and ductility, surface finishing as required

• Diameter Range: M3 – M24 (custom sizes available)

• Thickness: 0.6 mm – 6.0 mm (customizable)

• Operating Temperature Range: -40°C to +300°C (depending on material grade)

Applications

Our custom cup spring washers are widely used across multiple industries:

Quality Standards

All products are manufactured in strict compliance with international standards. Our manufacturing processes undergo rigorous quality control at each stage: raw material inspection, in-process dimensional checks, heat treatment verification, and final product testing. Conical spring washers are indispensable in engineering and manufacturing environments — their ability to absorb shocks, maintain tension, and compensate for material or component swelling due to temperature changes ensures dependable performance over time.

OEM & Customization Services

We specialize in custom OEM stamping solutions, including:

• Custom diameters and thicknesses (per customer drawings)

• Alternative material grades (alloy steel, spring steel, etc.)

• Special surface finishes

• Non-standard geometries per specific application requirements

For custom orders, please provide detailed specifications or CAD drawings for engineering review and quotation. Unlike mass-produced standard washers, our custom OEM Stamping Steel Cup Spring Washer is designed for optimal load distribution in mechanical assemblies. We support both high-volume production and smaller custom runs with flexible manufacturing processes to meet your project timelines.
In addition to cup spring washers, we manufacture a comprehensive range of stamped and custom fastener components: flat washers, spring lock washers, conical contact washers, non-standard stamping parts, and custom fasteners in various materials including carbon steel, stainless steel, brass, and aluminum.
