Avoid These Disc Springs Mistakes

May 24, 2024

Disc springs, with their versatility and potential, offer a plethora of benefits in numerous industries.  However, to truly harness their capabilities requires careful consideration and attention to detail to avoid common pitfalls in their utilization. Here are some key mistakes to steer clear of when working with disc springs to ensure optimal performance and longevity. 1. Neglecting Early Colla

How Does Mubea Extend Disc Spring Life?

March 29, 2024

We design our springs with the life of the application in mind. The fatigue life of the springs requires careful calculations, accounting for spring geometry, loading conditions, environmental factors, and more. One method to extend fatigue life beyond base DIN 16983 expectations is shot peening, a process that induces a compressive residual stress layer to avoid the propagation of microcracks in

Alkaline Electrolysers are Shaping the Future of Energy Production

February 12, 2024

Alkaline electrolysers use an alkaline solution (usually potassium hydroxide) to split water into hydrogen and oxygen gases through an electrochemical reaction called electrolysis. When an electric current is passed through the electrolyte, water molecules dissociate into hydrogen ions (H+) at the cathode and oxygen ions (O2-) at the anode. This hydrogen gas is collected for use as a fuel source,

Belleville Disc Spring Combinations - Designing Your Stack

February 25, 2022

Top: Parallel disc spring stack. Bottom: Series disc spring stack. Belleville Disc Springs are used as modular components. A group of individual Disc Springs stacked facing the same way is called a parallel spring stack. A group of individual Disc Springs that are stacked facing alternate ways is called a series spring stack. Disc Springs can be combined in many different ways to form stacks in

Belleville Disc Spring vs. Coil Spring…which one do I use?

February 9, 2022

A Coil Spring is a mechanical device made of an elastic material formed into the shape of a helix. A Belleville Disc Spring looks like a washer, but has a spring-like capability due to their conical design. Coil Springs and Belleville Disc Springs function similarly. Both products, when compressed, produce potential energy. The springs return to their original position after the load is lifted an

Design, Properties & Construction of Belleville Disc Springs

November 3, 2021

Belleville Disc Springs can be designed to meet the specific requirements of a variety of applications. The characteristic load curve is a representation of the force-deflection behavior of the spring. Depending upon the dimensions ratios, the characteristic load curve of a Belleville Disc Spring is more or less digressive up to the flat position. In special cases, Belleville Disc Springs can b

Looking for Nimonic 90 Material?

February 4, 2020

Currently Nimonic 90 material is only being produced in one mill in United Kingdom, mainly in wire and round bar. The plates, sheets, and strips are rarely produced because of the very low demand, therefore, it is very hard to find raw material in the required sizes to manufacture Disc Springs. Although not comparable, an available substitute would be Inconel 718, which is stable until 500°C and
