Belleville & Conical Washers



Belleville washers, or conical washers, are the strongest type of spring washers available. These types of washers are also referred to as disc springs and feature a conical shape that allows them to work like a heavy-duty spring and provide high spring loads in tight places. Belleville washers feature a convex disc that is supported by forces on the exterior and center of the disc. Disc springs can be configured singly or stacked to develop the optimal load. 

Belleville disc spring washers can achieve extensive force with short spring lengths. Conical washers produce little to no movement throughout the compression process. Willie Washer implements strict quality control procedures throughout the manufacturing process to ensure our selection of  conical disc springs do not underperform when subjected to specified loads over an extended timespan.

Versatility and Application Benefits of Belleville Washers

The ability to stack Belleville washers in different configurations makes them highly adaptable to various applications. Engineers rely on these conical spring washers to fine-tune load-bearing capabilities without increasing assembly size. Unlike traditional washers, which primarily distribute load, Belleville washers actively compensate for relaxation, creep, and thermal expansion, ensuring joints remain tight. 

In critical applications, such as wind turbines and power generation, Belleville washers with coned disc springs provide essential preload to prevent bolt loosening. Their ability to handle extreme loads makes them indispensable. By carefully selecting the right stacking configuration, engineers can achieve precise force distribution, extending the lifespan of components and reducing maintenance costs.

Industrial Uses and Stacking Configurations for Conical Spring Washers

Belleville disc spring washers feature a conically shaped disc form. These types of conical washers will deflect over time at a specified rate. These conical disc springs are utilized in industries such as pump manufacturing, valve development, and industrial automation. Conical spring washers maintain a high degree of tension and act as shock absorbers on vibrating parts, which keeps assemblies tight. 

These Belleville washers also compensate for thermal expansion and contraction on bolted joints. These conical springs are designed to be used as a single spring or in a stack formation. Conical washers can be stacked in a uniform direction or in an alternating fashion for all types of applications. If you need to support extensive loads in limited spaces, we recommend investigating the use of Belleville washers. Remember, it is important to keep friction in mind when stacking Belleville washers.

Custom Manufacturing and Precision Engineering

Willie Washer manufactures custom Belleville washers to meet specific project requirements. Our facility contains over 8,000,000 pounds of raw material, allowing us to produce washers in a wide range of sizes and materials. Our self-contained tooling department utilizes the latest EDM and CNC equipment, guaranteeing precise tolerances for every order.

With our in-house tooling department and advanced stamping equipment,  we ensure high-precision manufacturing. Each washer undergoes rigorous quality inspections and testing to ensure it meets exact specifications. Whether you need a small production run or a large-scale order, we deliver quality parts tailored to your needs.

Material Options and Durability

Conical washers have a long life when utilized in dynamic loads to ensure optimal performance. Conical / Belleville washers are commonly available in hardened steel and stainless, but can be made in other materials when required. 

These conical spring washers are offered in finishes such as black oxide, zinc & clear, zinc & yellow, phosphate & oil, and nickel. Willie Washer offers Belleville disc spring washers at affordable prices. All conical spring washers or conical disc springs are engineered with premium and long-lasting materials to ensure optimal performance. 

The material you choose for your Belleville washers plays a crucial role in how they perform in specific environments. For example, stainless steel washers excel in highly corrosive environments, and high-carbon steels provide enhanced strength and are highly resistant to thermal expansion. When corrosion resistance is key, coatings such as zinc or nickel provide additional protection, which helps extend the washer’s life. 

In addition to Belleville washers, we also offer wave spring washers. This type of washer is available in configurations such as 1 wave, 2 wave, and 3 wave to meet your needs. Contact a specialist to learn more about Belleville disc spring washers and conical washers.
