CONICAL WASHER

A CONICAL WASHER is an elastic washer with a curved, wave-shaped, or butterfly-like spring structure. When compressed, it generates a spring-back force that helps compensate for assembly clearance, maintain axial pressure, and provide auxiliary resistance against loosening.

Provides Elastic Preload

When compressed, the butterfly-shaped spring structure generates axial spring-back force, helping maintain contact pressure between components.

Compensates for Assembly Clearance

The elastic structure can absorb changes in clearance caused by dimensional tolerances, wear, or thermal expansion and contraction, helping reduce movement within the assembly.

Provides Auxiliary Anti-Loosening Performance

Continuous spring force can compensate for part of the preload loss and help reduce the possibility of screw loosening under general vibration conditions.

Saves Installation Space

The thin elastic structure can provide compression travel within limited axial space, making it suitable for compact and precision assemblies.

Suitable for Various Equipment

CONICAL WASHERS are commonly used in electronic and electrical equipment, automotive and motorcycle components, machinery, bearing assemblies, home appliances, and precision instruments.
