Disc Spring

Product Information

Disc springs, also known as Belleville washers, are conical-shaped mechanical components used to apply a precise and consistent axial force when compressed. They are a type of spring washer that looks like a slightly curved disc with a hole in the center.

Key Features:

  • Conical Shape: This gives them high load capacity and compact size.

  • Axial Load Handling: They generate force along the axis when compressed, making them suitable for preloading and cushioning.

  • Stacking Capability: Disc springs can be stacked in various configurations (parallel, series, or combinations) to adjust force and deflection characteristics.

Common Applications:

  • Vibration damping

  • Preloading ball bearings

  • Thermal expansion compensation

  • Safety valves and clutches

  • Automotive suspensions and braking systems

They’re valued for their high load capacity in a small space, long fatigue life, and reliable performance under dynamic or static conditions.
