Belleville Springs

UPC designs custom-engineered Belleville Springs for specialized applications where high precision accuracy is required. The products we create are used in space applications, industrial products, commercial aerospace, and transportation solutions. Belleville springs are ideal solutions for: distributing bearing loads, flange leakage, generating and sustaining tension, providing constant load, and spanning alignment holes. Our Belleville springs can be stacked or used individually to achieve specific load and travel requirements.

Load Patterns:

  • Linear rate
  • Reversing (fully snap over)
  • Semi-reversing (snap over and back)
  • Flat rate (at target zones)
  • Stacked set of different types to create unique load patterns

Belleville Spring Advantages:

  • Customizable load-deflection curves
  • Efficient space usage
  • High spring loads with small deflections
  • Keep mated joints tight
  • Long service life
  • Rounded edges to reduce stresses
  • Parallel stacking ability to increase load
  • Series stacking ability to increase deflection
  • Self damping
