Stacked Wave Disc Springs
The incorporation of multiple wave rows enables these springs to sustain greater loads compared to conventional wave disc springs.
Corrosion-Resistant Stacked Wave Disc Springs
Fabricated from 17-7 PH stainless steel and featuring multi-row wave configurations, these springs exhibit superior corrosion resistance compared to conventional steel springs while sustaining higher loads than typical wave disc springs
Wave Disc Springs
Deploy these high-carbon steel springs solely in environments free from corrosive elements.
Corrosion-Resistant Wave Disc Springs
Fabricated from stainless steel, these springs exhibit superior corrosion resistance compared to steel wave disc springs
Split Wave Disc Springs
A gap enables these springs to undergo compression without lateral expansion, preventing binding or deformation when installed within a housing featuring minimal clearance.
Belleville Disc Springs
Employ these springs in environments devoid of corrosive agents.
Corrosion-Resistant Belleville Disc Springs
Fabricated from stainless steel, these springs exhibit superior corrosion resistance compared to conventional steel springs. They are suitable for application on shafts, bolts, and valve ends to sustain tension and ensure component separation
Extreme-Temperature Belleville Disc Springs
These springs are capable of enduring temperatures ranging from -400° to 1100° F. Each is fabricated from 718 nickel, a high-strength, corrosion-resistant superalloy also referred to as Inconel.
Belleville Disc Springs for Ball Bearings
Mount these springs, referred to as bearing preload washers, adjacent to ball bearings to minimize noise and axial play
Belleville Disc Springs for Flange Bolts
Maintain pipe flange seals under rigorous operating conditions. When positioned beneath flange bolt heads, these springs mitigate the effects of impact forces, oscillations, and thermal cycling.
Mil. Spec. Belleville Disc Springs
These springs comply with MIL-W-12133
Corrosion-Resistant Curved Disc Springs
Fabricated from stainless steel, these springs exhibit superior corrosion resistance compared to conventional steel springs.
Curved Disc Springs
Deploy these high-carbon steel springs solely in environments free from corrosive elements.
Flat Disc Springs
These elastomeric flat springs support substantial loads, akin to Belleville washers, while exhibiting resistance to oxidation, lubricants, and wear.
Finger Disc Springs
Elevated protrusions, termed as projections, permit these elastic components to undergo compression without lateral expansion, thereby preventing binding or distortion within narrowly toleranced enclosures. Employ in conjunction with spherical rolling elements in exacting and rapid motion transmission systems to mitigate acoustic emissions, oscillatory motion, and material degradation.
Notched Disc Springs
These notches enhance the flexibility of these springs compared to Belleville disc springs and enable liquid to circulate around the spring, even during operation.
What Is a Disc Spring?
A disc spring is a conical-shaped spring designed to deliver high force in a compact space. When compressed, the spring flattens and stores mechanical energy, then returns to its original shape once the load is removed. Disc springs are widely used in applications requiring high loads, precise deflection control, and reliable performance in limited space.
Characteristics of a Disc Spring
- High Force in a Small Space: Provides much higher load capacity than coil springs of similar size.
- Compact and Efficient: Ideal where installation space is restricted.
- Stackable Design: Springs can be arranged in series, parallel, or combinations to achieve specific force–deflection curves.
- Predictable Performance: Delivers consistent and controllable force under heavy loads.
- High Fatigue Strength: Designed for repeated cycles in demanding environments.
- Wide Material Options: Available in carbon steel, stainless steel, and high-performance alloys.
- Customizable Geometry: Thickness, outer/inner diameter, and stacking patterns can be tailored for the required load.
How Disc Springs Work
A disc spring works by resisting force when it is compressed. When a load is applied:
The conical disc flattens, decreasing its height.
Mechanical energy is stored within the material due to deformation.
Once the load is released, the spring returns to its original conical form, providing strong restoring force.
By stacking multiple disc springs:
Parallel stacking increases force.
Series stacking increases deflection.
Combination stacks allow precise control of both load and travel.
This flexibility makes disc springs ideal for applications that demand high force in a limited space.
Common Materials of Disc Springs
Disc springs are made from various materials to meet load, temperature, and environmental requirements:
- Carbon Steel: Standard choice for general industrial applications.
- Stainless Steel (e.g., 301, 302, 17-7PH): Corrosion-resistant for moisture, chemicals, and outdoor environments.
- Alloy Steel (e.g., Chrome Vanadium, Chrome Silicon): Excellent for high-stress or high-temperature uses.
- Inconel: Suitable for extreme temperatures and corrosive industrial environments.
- Hastelloy: Ideal for chemical processing and highly corrosive environments.
- Elgiloy: High strength, corrosion resistance, and excellent fatigue performance.
- Titanium: Lightweight with strong corrosion resistance for aerospace or weight-critical applications.
