Spring Washers

Spring washers are disks of metal that form an irregular shape, so that when the washer is loaded it acts like a spring and deflects, providing a preload between the two surfaces. There are many different spring washer types including belleville washers, bowed or curved washer, conical washers, finger washers, wave washers and adjustable spacers.

Spring washers are primarily used in applications where manufacturing assemblies need a part to:

• Take up play
• Eliminate rattle
• Maintain assembly tension
• Compensate for expansion or contraction in materials after assembly
• Absorb intermittent shock loads
• Provide a controlled reaction under dynamic loads

Product Description

Spring washers provide an easy way to compensate for differences in stacked tolerances or better known as “end play”. Spring washers also provide a low cost and an efficient solution for many of these following design requirements:

• Compensating spring force
• Preloading on a bearing
• Constant tension on fasteners
• Absorption of intermittent shocks from starting and stopping

What To Look For

When looking for a spring washer it is important to consider the correct size specifications your going to need including inside diameter, outside diameter, thickness, working weight and working load. Common materials of construction of spring washers include stainless steel, spring steel, nickel base alloy, copper base alloy or bronze. Each material has it’s own strengths and weaknesses and different materials may be better for different jobs.
