Belleville Spring Washers

Belleville Spring and Washer Advantages

Coned disc springs perform many of the same functions as helical springs but provide better performance in applications with limited space. Belleville washers are available in several high-performance materials, such as 17-7 PH Stainless Steel, 301 Stainless Steel, Inconel and finished carbon steel. Specific features include:

• High Spring Rate
• Resolves Thermal Expansion
• Absorb Shock
• Provide Dampening
• Highly Configurable
• Support high tension and support high loads in bolted applications

Additional Belleville Spring and Washers Industrial Applications

Belleville spring washers are designed to create tight connections better than conventional springs and maintain bolt preload. Some of the applications for Belleville springs and washers include Valve live loading, Pump and valve manufacturing and Industrial automation.
 
Contact our engineers for assistance finding the right Belleville washers for your application.

Belleville DIN and Disc Springs

DIN and disc springs are designed for use in demanding applications when a large number of deflection cycles or forces are critical. Belleville DIN and disc washers provide numerous applicable advantages when a specific load or travel is desired.
Use examples include:

• Punch and die sets
• Clutch brake mechanisms
• Bearing assemblies
• Valve live loading
• Heavy equipment
• Pump and valve manufacturing

Belleville Flange Washers

Flange washers maintain sufficient bolt tension and resultant gasket stresses in high-temperature and high-pressure applications and do not need to be retorqued once installed. Flange washers are ideal for industries that utilize piping flange joint assemblies, such as petrochemical, dictate a low tolerance for fugitive emissions.

Belleville Flange Washers Related Industries

Examples include oil & gas, pump & valve manufacturing, coastal applications, flange/bonnet gasket live loading, heat exchangers, actuators and cryogenic applications.

Imperial and Metric Belleville Washers

Imperial washers and produce high loads in a small space and prevent bolt tension loss due to differential thermal expansion high-temperature bolt yield, packing and gasket relaxation, and vibration. Metric Belleville washers feature the same design and high-performance material options as imperial coned disc springs but in metric sizes.

Imperial & Metric Related Industries

We offer washer solutions for cryogenic processes, extreme temperature cycling, heavy vibrations and virtually every industrial applications. Visit our Belleville spring washer Industries Served Page for more information on uses for imperial & metric Belleville washers.

Belleville Spring and Washer Size Options

DIN & Disc Springs: DIN and disc springs are available in metric sizes from 2.5mm to 125mm.
Flange Washers: Choose from a range of inside diameters, outside diameters, heights, and thicknesses.  
Imperial: Conical disc springs in imperial sizes with an inside diameter from 7/64” to 2 ½” and outside diameters from 1/4” to 5.50”.
Metric: Metric conical spring washers are offered in Belleville spring, flange and DIN/disc spring options with metric sizes ranging from 4mm to 125mm, depending on the style selected.

Characteristics of Belleville Springs

Belleville springs are characterized by four geometrical variables including outside diameter (OD), inside diameter (ID), thickness (T) and overall height (H). Carefully consider each measurement before selecting a Belleville disc spring. Contact our engineers for assistance for assistance in selecting the right Belleville spring washer for your bolting system.

Configurable to Meet Your Load and Deflection Requirements

A single Belleville spring washer provides specific load and deflection, while stacking two or more conical spring washers increases load and/or deflection. They are also highly configurable to meet a range of load requirements. Different methods of stacking Belleville springs & washers include:

• Parallel stacking to double the load with no deflection increase
• Series stacking to double deflection with no load increase
• Parallel-series combination stacking to double load and deflection

High-Quality Belleville Springs Engineered for Precision

As a Belleville spring washer manufacturer in the USA for over 70 years, Belleville springs have been an integral part of the Solon Manufacturing product family. While other companies provide washers, springs, and locknuts, Solon’s standard for excellence continues to distinguish us from our competitors.
 
We offer coned disc springs in a variety of styles, sizes, heights, and thicknesses to meet different tolerance requirements. When selecting a spring, consider your size and load requirements, as well as the operating environment. Material selection is also important and determined by your bolt material, operating temperature, environment, and application.
