Custom Belleville Disc Springs

Rondelle Belleville Borrelly

Borrelly Spring Washers specializes the design and manufacturing of custom Belleville disc springs. With decades of experience and deep technical expertise, our Engineering & Design Department has addressed some of the most demanding problems for very high-tech sectors such as offshore, nuclear, petrochemical and aerospace. Whether you are looking for a specific load-deflection profile, operating temperature range, or material resistance, our engineers can help create the perfect custom Belleville washer for your technical challenge.

Belleville Disc Springs Customized to Fit Your Needs

At Borrelly, we can develop fully custom Belleville spring washers to match your project’s exact requirements:

  • Geometrical properties: inner/outer diameter, thickness, height under load
  • Stacking options: for increased load or deflection (series or parallel stacking)
  • Material selection: for static or dynamic use, extreme temperatures, or corrosive environments
  • Surface treatments: passivation and coatings to improve durability and chemical resistance

Our custom Belleville disc springs are engineered to meet your specific application’s contrainsts, whether used as a single disc or in stacked configurations. From initial analysis to full-scale production, our team will work alongside yours to define the best technical solution.

All parts manufactured can be supplied with detailed documentation and certifications upon request, including:

  • Material conformity
  • Load and stiffness test reports
  • Elastic curve data
  • Fatigue and dynamic test results
  • Cleanliness and dimensional inspection certificates
