Belleville Washers

Belleville washer or Belleville disc springs have a conical shape that generates a high force in a concise spring length and minimal movement when compressed. Belleville washers' advantages include high load capacity within a small space, shock absorption, dampening functionality, high tension maintained in bolted applications, and load characteristics that can be modified by stacking.

Belleville Washers Overview

Custom Manufacturing

Custom Belleville Washers

All our disc springs are subject to exacting manufacturing and quality control standards. All discs are preset so that they will not significantly relax under load over time. MW also offers pre-stressed disc springs specifically sized for use with bolts.

Belleville Washer Manufacturing & Configurations

Belleville washers and other disc spring styles can be used singly or in stacks to achieve a desired load and travel. In general, they function best under conditions requiring very high load in confined space or short travel. Under these constraints, it is often not practical or even possible to use a coil spring. In disc spring stacks, particularly those with parallel units, friction should be considered. Sliding friction is created at the disc’s adjoining, moving surfaces. As a result, the deflection which occurs when loading a stack of discs will lag as the stack is unloaded (hysteresis). This characteristic may be taken advantage of in shock or oscillatory loaded systems needing damping.

Materials

MW stocks standard and specialty materials of all types. Below are some commonly requested materials used to manufacture Belleville washers.

Belleville Washer Configurations

Parallel Stack

If you stack 6 discs in parallel, you gain 6 times the load capacity of a single disc, but your maximum deflection is that of a single disc.

Belleville washer & disc spring stacking - Series & parallel configuration

Series Stack

If you stack 5 discs in a series, you achieve 5 times the deflection of one disc, but the same load as a single disc.

Mixed Stacking – Parallel & Series

Belleville washers stacked in series and parallel in combinations can be arranged to produce almost any load-vs.-deflection trend that you need (linear, progressive, regressive, etc.)
