1. Product Overview

Belleville Spring Washer – Compact Design, Reliable Spring Force

A Belleville Spring Washer is a conical disc-shaped spring component that generates axial force when compressed. Its unique geometry enables it to deliver substantial spring force within a relatively small installation space.

Compared with conventional flat washers, Belleville spring washers provide elastic deflection and can help maintain clamping force, compensate for limited joint settlement, and accommodate small dimensional changes in properly designed assemblies.

Depending on the application, Belleville washers can be manufactured from alloy spring steel, high-carbon spring steel, stainless steel, nickel-based superalloys, or suitable copper alloys.

Our material selection options include 51CrV4, 60Si2MnA, Ck67, 65Mn, 17-4 PH, 17-7 PH, 316 stainless steel, Inconel alloys, and beryllium copper.

Each material offers different advantages in terms of mechanical strength, fatigue performance, corrosion resistance, temperature capability, electrical conductivity, and cost. The appropriate grade should be selected according to the actual working conditions rather than material name alone.

Whether you need standard disc springs, customized dimensions, specific load-deflection characteristics, or special material requirements, we can evaluate your specifications and discuss a suitable manufacturing solution.
