Split wave spring washer

What is a split wave washer?

A split wave washer is a type of safety washer designed to absorb vibrations, compensate for load variations and maintain tension in a screwed assembly. It is designed to provide an elastic preload between two assembled parts, generally in a screwed assembly.

It is characterized by :

• A corrugated shape, which enables it to act like a spring and exert a constant force on the assembly.

• A slot, which enhances its flexibility and shock-absorbing capacity.

What material for split corrugated washers?

Split corrugated washers are manufactured in several materials, depending on their use:

• Stainless steel: ideal for damp or corrosive environments (marine, food processing).

• Zinc-plated steel: more economical and resistant to moderate corrosion.

• Spring steel: used for applications requiring high elasticity.

• Brass, copper, aluminum: less common, these materials are used for specific applications, notably in electronics.

Manufacturing involves a cutting and forming process, where the corrugation and slot are created to give the washer its mechanical properties.

How do split wave washers work?

Split corrugated washers are mainly used to :

• Reduce mechanical play: they absorb pressure variations and prevent the loosening of screws and nuts.

• Dampen vibrations and shocks: perfect for machines in motion.

• Improve load distribution: limit excessive pressure to a small area.

• Increase assembly life: by reducing wear due to shock and vibration.

• Guarantee optimum tightening: by maintaining a constant force on the fastener.

What's the difference with other safety washers?

• Unlike Grower washers (conventional lock washers), they are not only designed to lock screws, but also to compensate for tolerance deviations between parts.

• They exert a continuous elastic force rather than a simple frictional effect.

What are the industrial applications for split wave washers?

Split wave washers can be found in a number of sectors:

• Mechanical industry: fastening of components subject to vibration (motors, pumps, compressors).

• Automotive and rail: they guarantee optimum hold under vibration.

• Aerospace: their compact size and ability to absorb load variations are invaluable.

• electronics and high-precision: they compensate for play in precision assemblies.

How to choose a split wave washer?

To help you choose the right washer, here are the main criteria to consider:

• Material: stainless steel for corrosion resistance, zinc-plated steel for value for money, spring steel for high elasticity.

• Internal and external diameters: these must match the diameter of the screw or bolt used.

• Thickness and amplitude of corrugation: these determine the clamping force exerted.

• Applied load: some washers are better suited to heavy loads, others to small electronic parts.

What are the technical characteristics of split wave washers?

Split wave washers are made from high-quality materials such as stainless steel or carbon steel, guaranteeing durability and performance. They are available in a range of sizes and shapes to suit every application. Here are some key technical data for split wave washers:

• Inside diameter: 87.38 mm

• thickness: 0.76 mm

• Material: stainless steel

• Outside diameter (max.): 98.43 mm

• Number of waves: 4

• Unit load: 284.686 N

• Height load: 2.769

These specifications enable you to choose the washer best suited to your needs, guaranteeing optimum performance in your application.

Complementary products to split wave washers

They are often used with :

• Flat washers: to distribute the load more evenly over the contact surface.

• locknuts: to reinforce the strength of assemblies subject to vibration.

• High-strength bolts: to ensure reliable tightening.

• Threadlockers (e.g. Loctite): for additional protection against loosening.
