Thickness: 1.3mm
Material: Spring Steel

Conical Spring Washer (Belleville Washer) is a disc-shaped washer designed to provide high load capacity and maintain tension in bolted joints. Its conical shape allows it to act like a spring, absorbing shock, vibration, and thermal expansion while keeping the fastener securely tightened.

What Makes It Different

Unlike flat washers, conical spring washers exert continuous axial force, helping prevent loosening under dynamic loads. They can handle high loads in a compact space, making them ideal where space is limited but strong preload is required.

Applications

Commonly used in automotive assemblies, heavy machinery, electrical equipment, flanged joints, and industrial applications, especially where vibration resistance, load retention, and consistent clamping force are critical.
