Conical Disc Washer

🔩 Conical Disc Washer

(High Load-Bearing Spring Washer for Dynamic and Static Fastening Applications)

Neo Fasteners supplies precision-engineered Conical Disc Washers designed to absorb heavy loads, maintain bolt tension, and reduce loosening in high-vibration environments. Also known as Belleville Washers, these washers are commonly used in preloaded joints, vibration damping, and thermal expansion compensation systems across industrial, automotive, and aerospace sectors.

Manufactured from high-grade spring steel, stainless steel, or alloy steel, our washers are built to deliver consistent deflection, elasticity, and reliable load distribution.

🔹 Product Overview:

A Conical Disc Washer is a washer shaped like a truncated cone that acts as a spring to apply a preload or flexible support between two surfaces. When compressed, it stores mechanical energy and provides axial flexibility, maintaining clamping force and absorbing shocks or vibrations that could otherwise loosen fasteners.
