A Spring washer is an elastic fastening component designed to provide consistent preload, absorb axial load, and maintain tension in mechanical assemblies. Engineered to reduce wear and stabilize torque, the spring washer ensures long-lasting, reliable performance across rotating, folding, and automatic closing mechanisms.
Available in multiple shapes—including conical spring washer, disk spring washer, and cone washers—this component is widely used in precision assemblies such as hinges, rotating shafts, and bearing spring washer applications.
For enhanced fastening results, spring washers are often used together with spring washers and flat washers to increase stability and distribute load efficiently.

what is a spring washe?
A spring washer is a type of washer designed to provide elastic force within a fastening system. Unlike flat washers that simply distribute load, a spring washer adds tension, preload, and locking capability to prevent loosening under vibration, shock, or movement.r
Spring washers are essential for folding, rotating, twisting, and automatic closing mechanisms, ensuring components remain stable under movement, vibration, and torque.
Typical applications include:
Provides elastic preload for smooth and controlled folding or opening.
Enhances the “quality feel” during movement and improves durability.
Generates torque inside the shaft, absorbing axial load.
Reduces wear, extends shaft life, and maintains constant tension.
Acts as a bearing spring washer to compensate for axial play.
Ensures stable rotation and minimizes vibration.
Used in smart lids, automated doors, foldable devices, and robotic joints.
Ensures reliable elastic return force and extends cycle life.
Motors, gear housings, CNC equipment, and clamping systems.
Prevents loosening under vibration and maintains long-term stability.
A spring washer provides elastic preload, absorbs axial load, prevents loosening, and maintains stable tension in mechanical assemblies.
Flat washers distribute load and protect the surface.
Spring washers add elasticity and locking force to prevent loosening.
Often, spring washers and flat washers are used together for enhanced performance.
They are widely used in hinges, rotating shafts, bearings, clamping systems, and vibration-prone equipment.
