Belleville Washer – Engineered Custom Design

At Solon, custom Belleville washers begin with collaboration. Our experienced engineers work directly with your design team to understand:

Required load and deflection characteristics
Available installation space and stack configurations
Operating temperatures, vibration, and fatigue demands
Environmental exposure (corrosion, chemicals, moisture)

Whether you provide detailed drawings or prefer to discuss functional requirements, our team translates performance goals into optimized washer geometry and material selection. The result is a disc spring solution that performs consistently over its service life.

Custom Sizes, Thicknesses & Load Profiles

Solon manufactures Belleville custom spring washers to precise specifications, including:

Custom outside and inside diameters
Controlled thickness and cone height
Single or stacked washer configurations
Tailored spring rates and load-deflection curves

This flexibility allows engineers to fine-tune preload, compensate for thermal expansion, manage vibration, or maintain clamp load in compact assemblies where traditional springs are impractical.

High-Performance Materials for Demanding Applications

Material selection is critical to the performance of Belleville washers. Solon offers a broad range of high-performance alloys selected to meet mechanical, thermal, and environmental demands, including options for:

High-cycle fatigue resistance
Elevated or cryogenic temperatures
Corrosive or chemically aggressive environments
Long-term load retention

Our engineering team helps determine the ideal material based on stress levels, temperature exposure, and service life expectations.

Specialized Finishes & Compliance Capabilities

To further enhance performance and durability, Solon provides a range of finishing and coating options, specified or customized to meet application requirements such as corrosion resistance, friction control, or vibration damping. Available finishes are designed to support RoHS compliance, AMS specifications, corrosion protection, improved wear or fatigue performance, while providing chemical resistance.
