CURVED WASHER

A CURVED WASHER is an elastic washer with a raised curved or bowed profile. It may also be referred to as a Bowed Washer or Curved Spring Washer. When compressed, the washer generates axial spring-back force, helping compensate for assembly clearance, maintain contact pressure, and reduce component movement.

Provides Stable Elastic Preload

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

Compensates for Assembly Clearance

The CURVED WASHER can absorb clearance variations caused by dimensional tolerances, component wear, and thermal expansion or contraction, helping reduce looseness within the assembly.

Reduces Axial Movement

Proper preload can help limit axial displacement of gears, bearings, shafts, and moving components, reducing abnormal noise and vibration.

Thin Profile Saves Installation Space

Compared with conventional spring elements, a CURVED WASHER can provide elastic travel within limited axial space, making it suitable for compact assemblies.

Suitable for Precision Assemblies

CURVED WASHERS are commonly used in motors, bearings, gears, electronic equipment, automotive and motorcycle components, automation equipment, and precision instruments.
