Belleville Springs
Belleville Springs
Belleville Springs Manufacturer, Supplier & Exporter in India
AN Fasteners is a leading manufacturer, supplier, and exporter of premium Belleville Springs (Disc Springs) engineered for high-load and compact mechanical applications. Known for their exceptional force-to-deflection ratio, our Belleville washers provide superior performance, reliability, and durability in space-constrained, high-pressure environments.
What Are Belleville Springs?
Belleville Springs, also known as disc springs, are conical-shaped washers that deflect under axial load to exert a high spring force over a short displacement. This unique design allows them to support heavy loads in limited space, making them an ideal choice for applications demanding compact size with high performance.
Manufactured using hardened and tempered materials such as Spring Steel, Stainless Steel, Inconel, and more, our Belleville springs undergo precision forming and heat treatment to ensure maximum resistance to fatigue, corrosion, and stress relaxation.
We offer both standard sizes and custom-engineered configurations to meet specific requirements across critical industries.
Key Features of Belleville Springs
- High load capacity with compact form factor
- Suitable for static, dynamic, and shock load conditions
- Single or stacked arrangement (parallel, series, or combination) for adjustable load/deflection profiles
- Materials: Spring Steel, SS 304/316, Inconel, Phosphor Bronze, and more
- Surface finishes: Zinc Plated, Black Oxide, PTFE Coated, Passivated
