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.
