Product Description

Product Description

DIN6796 Belleville washers feature a unique conical disc design, with a thick center and thin edges, providing excellent elasticity and high preloading force to maintain constant clamping pressure in bolt connections, effectively preventing loosening and fatigue relaxation. Its outstanding vibration and impact resistance make it ideal for automotive suspension systems, engine fasteners, wind power equipment, and machinery in high-vibration, high-load environments.
 
 

Dacromet Coating Characteristics

65Mn Spring Steel Characteristics

Dacromet coating, after special processing, achieves over 500 hours of neutral salt spray (NSS) testing, offering exceptional corrosion resistance far superior to traditional zinc plating. Its coating is uniform and strongly adherent, with no risk of hydrogen embrittlement, making it ideal for high-strength fasteners, automotive components, and outdoor mechanical equipment for long-lasting protection.

65Mn is a high-carbon manganese spring steel characterized by its high strength, hardness, and excellent elasticity. After heat treatment, it demonstrates outstanding fatigue resistance and wear resistance, maintaining performance under high stress and repeated impacts. It is widely used in spring washers, Belleville washers, and various mechanical spring components.

Other materials and finishes are available	merit
65Mn + Dacromet	Superior corrosion resistance and high-strength performance.
65Mn + Black Oxide	Enhanced wear resistance and anti-corrosion properties.
65Mn + Blue-White Zinc	Excellent rust protection with a clean, bright finish.
SS304 + Natural Polishing	Outstanding corrosion resistance and a smooth, polished surface.

Product Applications

Functional Features of DIN6796 Belleville Washer

1. Anti-Loosening
The conical design provides constant pressure to prevent bolt loosening.
2. Vibration Resistance
Effectively absorbs vibrations to avoid bolt detachment.
3. Load Distribution
Evenly spreads pressure to prevent localized stress.
4. Compensation for Bolt Relaxation
Automatically adjusts for bolt relaxation over time.
5. Enhanced Preload Stability
Maintains strong connections and reduces maintenance.

Engine Mounting System

Belleville washers are used for bolt fastening on engine covers, cylinder heads, and intake/exhaust manifolds, effectively preventing loosening caused by high temperatures and vibrations, ensuring long-term stable operation of the engine.

Suspension System

In automotive suspension systems, Belleville washers are used for fastening connectors and brackets, providing excellent shock resistance and preventing loosening caused by road impacts.

Brake System

Applied to the fastening bolts of the brake master cylinder and brake discs, enhancing thread vibration resistance to prevent loosening during high-speed braking, ensuring driving safety.

Transmission Mounting Bolts

At the connection between the transmission and the engine, Belleville washers effectively prevent loosening caused by intense vibrations during power transmission, ensuring smooth power output.
