Belleville Disc Washer Springs - Learn About

High Loads in Small Spaces

When your compression spring application requires a high load in small spaces, Lee Spring's Belleville Disc Washers can be the solution. Their conical configuration enables them to support high loads with relatively small deflections and solid heights compared to helical springs. Belleville Washers are often used to solve vibration, thermal expansion, relaxation and bolt creep problems.

Lee Spring Standard Series Belleville Disc Washers are manufactured from 300 Series Stainless Steel. Additionally, Lee Spring Standard Series Belleville Disc Washers are passivated in accordance with specification ASTM A967 (supercedes QQ-P35) to remove contaminants and further improve resistance to corrosion. 300 Series Stainless Steel is slightly magnetic and is recommended for applications with temperatures up to 500°F (260 °C).

The Lee Spring DIN Belleville Disc Washer Series offers metric disc spring washers to meet global demand for sizes specified by DIN .  Lee Spring also expand on size options past DIN &#;s standard size tables, made to DIN manufacturing and quality specifications to provide component flexibility for product designers. DIN Belleville Disc Washers are made with 51CrV4 spring steel (AISI ) and finished with a phosphate and oil surface for general protection from corrosion. 

DIN Belleville Disc Washer Series designs are classified into three groups based on the material thickness:

Group 1 &#; This range applies to disc spring washers with material thickness less than 1.25mm.  Lee Spring DIN Belleville Disc Washer Series include 88 sizes in Group 1, over a selection of outside diameters from 6mm (0.236&#;) to 40mm (1.575&#;) with inside diameters from 3.2mm (0.126&#;) to 20.4mm (0.803&#;).

Group 2 &#; This range applies to disc spring washers with material thickness from 1.25mm through 6mm.  Lee Spring DIN Belleville Disc Washer Series include 161 sizes in Group 2, over a selection of outside diameters from 20mm (0.787&#;) to 200mm (7.874&#;) with inside diameters from 10.2mm (0.402&#;) to 102mm (4.016&#;).

Group 3 &#; This range applies to disc spring washers with material thickness over 6mm through 14mm.  Lee Spring DIN Belleville Disc Washer Series include 41 sizes in Group 3, over a selection of outside diameters from 100mm (3.937&#;) to 250mm (9.843&#;) with inside diameters from 51mm (2.008&#;) to 127mm (5.000&#;).

Conical Washers & Belleville Spring Application

Understanding Belleville or Conical Washers

Belleville washers&#;also known as conical washers or disc springs&#;are designed to help fasten heavy loads and withstand vibrations or thermal expansion without a loss of torque. As a type of heavy-duty spring washer, their convex shape maintains optimal axial loading (i.e., applying force to a structure along its axis) to prevent hardware creep challenges.

Below, we&#;ll provide a breakdown of what you need to know about Belleville washers.

How Do Belleville Washers Work?

To explain the belleville spring application, a Belleville washer&#;s conical shape operates as a simple spring when nuts and bolts are tightened. Rather than multiple coils that compress, a disc spring&#;s shape &#;deflects&#; until it resembles a flat washer. The resistance against this deflection secures the load and allows the hardware to withstand vibrations and other conditions.

When working with heavy loads in tight spaces or meeting heavy spring load requirements, Belleville washers will be the best choice for your application. This is because they allow significantly less movement and compression when fastening the same load compared to coil springs.

However, for the same reason, loads that are too light will not benefit from a Belleville washer&#;s deflection and will remain stationary instead.
