DIN 6796 Disc Spring Washer

French-invented anti-loosening solution offering consistent dimensional accuracy and superior performance for industrial bolted connections.

Product Overview

The DIN 6796 Disc Spring Washer, commonly known as the Belleville washer, represents a groundbreaking French innovation from the late 19th century. Conceived by engineer Julien Belleville, this precision component was specifically designed to solve critical bolt loosening issues in mechanical systems.

As a fully compliant DIN 6796 standard component, it undergoes rigorous testing to ensure consistent dimensional accuracy, premium material composition (typically high-grade spring steel or stainless steel), and predictable performance metrics for seamless integration with ISO and DIN standard bolts and screws.

Key Features & Benefits

Superior anti-loosening properties for enhanced connection security
Consistent dimensional accuracy and predictable performance
Sustained preload force through elastic deformation
Absorbs vibrational energy and resists cyclic loading
Compensates for thermal expansion and contraction
Non-linear load-deflection characteristics for stable clamping force
Extends service life of critical assemblies
Reduces unplanned downtime and maintenance costs

Technical Design

The washer's distinctive frustoconical disc geometry enables it to exert sustained preload force, creating a mechanical buffer that prevents micro-loosening that can escalate into catastrophic system failure. Unlike conventional flat washers, it maintains stable clamping force even under extreme conditions.

Industrial Applications

Ideal for heavy-duty applications including wind turbine nacelles, automotive powertrains, industrial presses, railway bogies, and other demanding industrial environments where reliable bolted connection security is critical.
