Product Description
Detailed Specifications & Features
Disc Spring Washer (DIN6796) Belleville-Invented Safety for Bolt and Screw Connections
Engineering Excellence in Connection Security

In industrial engineering, the integrity of bolt and screw connections forms the foundation of operational safety and equipment reliability. The Disc Spring Washer (DIN6796), universally recognized as the Belleville washer, represents a century of innovation in addressing this critical need.

Originally conceived by French engineer Julien Belleville in the late 19th century, this pioneering component was specifically engineered to combat the pervasive issue of spontaneous bolt loosening that had long plagued mechanical systems across industries.

Quality and Compliance

As a fully compliant DIN6796 standard component, each washer undergoes rigorous certification to ensure uncompromising quality. Manufactured from premium materials including:

  • 70# high-carbon spring steel
  • 72B alloy steel
  • Corrosion-resistant SUS304 stainless steel

Precise dimensional tolerances guarantee seamless compatibility with ISO/DIN standard fasteners.

Technical Superiority

The defining frustoconical (convex disc) geometry enables exceptional elastic deformation, generating sustained preload force that acts as a mechanical buffer against:

  • Vibration
  • Thermal expansion and contraction
  • Cyclic mechanical stress

Unlike conventional flat washers, the Belleville washer's non-linear load-deflection curve ensures clamping force remains stable even during micro-movements, effectively preventing rotational loosening and fatigue-induced failure.

Critical Applications

This engineering marvel provides indispensable security across high-stakes industries:

  • Aerospace: Securing critical engine components and landing gear where vibration resistance and lightweight design are paramount
  • Medical Equipment: Ensuring precision in surgical instruments and diagnostic devices with non-toxic, corrosion-resistant materials meeting strict hygiene standards
  • Heavy Machinery: Withstanding rugged conditions in mining trucks and construction equipment where dust, moisture, and heavy loads demand durable performance
  • Automotive: Maintaining integrity in powertrains and suspension systems under extreme temperature fluctuations and mechanical shock
Operational Benefits

By maintaining optimal bolt tension over extended service intervals, the DIN6796 washer directly reduces maintenance costs, minimizes unplanned downtime, and mitigates the risk of catastrophic equipment failure. It transforms bolted connections from potential weak points into pillars of reliability.
