Disc Springs – Built for the Trade
Disc springs are high-force, compact washers that store energy under axial load. Used in preloading, vibration damping, and shock absorption, they pack serious performance into a small footprint.
Godiva Bearings supplies disc springs in carbon steel, stainless, and specialist alloys. Always in stock. Always for the trade.
What Are Disc Springs?
Disc springs (also called Belleville washers) are conical-shaped spring washers that compress under load to provide high axial force.
They can be:
- Used individually for small movements
- Stacked in series for greater deflection
- Stacked in parallel for greater load
Godiva supplies:
- DIN 2093 disc springs
- Custom sizes on request
- Pre-stacked spring sets
What Are They Made Of?
Engineered for reliability under repeated load:
- High-carbon spring steel – For general industrial use
- Stainless steel (AISI 301/316) – For corrosive or hygienic settings
- Inconel or other alloys – For high-temperature or extreme conditions
All springs are:
- Shot peened and pre-set (where required)
- Chamfered for easy stacking
Where Are Disc Springs Used?
These types of springs are found where space is limited but high load or precise deflection is needed:
- Valve preloading: In hydraulic or pneumatic control blocks
- Clutches and brakes: In automotive and industrial drives
- Gearbox assemblies: For axial play control
- Flange connections: Maintaining bolt preload under thermal cycling
- Pumps and seals: Ensuring contact force in dynamic seals
- Wind and solar: Where thermal expansion varies loads
If movement needs managing, disc springs do the job.
What Do They Help Prevent?
Specced and fitted correctly, these springs prevent:
- Bolt loosening under vibration or thermal cycling
- Wear from excessive shaft play
- Seal failure due to inconsistent contact
- Damage from shock loading
- Load drift over time in clamped joints
They lock, cushion, and correct.
Installation, Use and Maintenance Tips
Trade best practice:
- Always follow DIN stacking rules for force/deflection
- Use hardened washers between spring stacks
- Avoid stacking without alignment
- Don’t reuse deformed or corroded discs
- Grease for longer life where fretting may occur
Store stacked sets flat to avoid permanent distortion.
Conclusion: Small, Strong, and Smart
Disc springs do the job where coil springs or shims fall short. Big force. Tight space. Real control.
Godiva Bearings keeps a full range on hand — standard and special. Always for the trade. Always supported.
