Spring washers, also known as disc springs, are a type of
mechanical fastener that are commonly used to prevent loosening or to absorb
shock or vibration in various applications. They are widely used in automotive,
aerospace, industrial, and construction industries. In this blog, we will
explore the different types of spring washers, their uses, and advantages.

Types of Spring Washers
There are several types of spring washers available in the market, each
with its unique design and function. The following are some of the most
commonly used spring washers:
Belleville Washers: Belleville
washers, also known as conical spring washers, are cone-shaped washers that are
commonly used to absorb shock and vibration. They are designed to provide a
high spring rate and are often used in applications where space is limited.
Wave Washers: Wave washers are
disc-shaped washers that have a wave-like structure. They are used to absorb
shock and vibration and are often used in electrical applications, such as
motors and generators.
Finger Washers: Finger washers
are made of several flat, curved leaves that are stacked together. They are
used to provide a constant load and are commonly used in clutch and brake
applications.
Curved Spring Washers: Curved
spring washers are disc-shaped washers that have a curved shape. They are used
to provide a constant load and are often used in ball bearing assemblies.
Uses of Spring Washers
Spring washers are used in a wide range of applications, including:
Fastening: Spring washers are
often used in fastening applications to prevent loosening due to vibration.
They are commonly used in nuts and bolts, screws, and other threaded fasteners.
Shock Absorption: Spring
washers are also used to absorb shock and vibration. They are commonly used in
heavy machinery, such as compressors and engines, to reduce noise and prevent
damage.
Electrical Applications: Spring
washers are used in electrical applications to provide electrical continuity
and reduce electromagnetic interference.
Advantages of Spring Washers
Spring washers offer several advantages over traditional fasteners,
including:
Prevent Loosening: Spring
washers are designed to prevent loosening due to vibration, making them ideal
for applications where fasteners are exposed to high levels of vibration.
Absorb Shock and Vibration:
Spring washers are designed to absorb shock and vibration, making them ideal
for heavy machinery and other applications where noise and vibration are a
concern.
Reduce Stress: Spring washers
distribute the load evenly, reducing the stress on the fastener and the
surrounding material.
Easy to Install: Spring washers are easy to install and do not require any special tools or equipment.
Conclusion
Spring washers are a versatile and cost-effective solution for preventing
loosening, absorbing shock and vibration, and reducing stress. With several
types of spring washers available, it is important to choose the right type of
washer for your application. If you are unsure which type of spring washer is
right for your application, consult a professional or a supplier who can help
you choose the right one.
