What is a Sinus Washer?

Sine washers are essential mechanical components in many industrial and technical applications. They absorb play between parts, reduce vibration and improve assembly stability.

What are the features and specifications of a Sinus Washer ?

Sinus washers are essential components in many industries. Here are some of their key features and specifications:

• Material: They are generally made of stainless steel (inox) or carbon steel. Stainless steel is prized for its corrosion resistance and exceptional durability, while carbon steel is a more economical option offering high mechanical strength.

• Internal diameter: The internal diameter of these products varies according to size and application. It's crucial to choose a washer with an inner diameter that perfectly matches the axle or screw you're using, ensuring an optimum fit.

• Load: They are designed to withstand relatively light axial loads. The maximum load a washer can support depends on its size, material and design. It is important to check the load specifications to ensure that the washer can withstand the forces applied without deforming.

• Height: Washer height varies according to size and application. Choosing a washer with the right height is essential to guarantee optimum performance and effective absorption of axial play.

• Backlash: Sinusoidal washers are specially designed to absorb axial backlash, offering greater precision and reliability in mechanical assemblies. They compensate for tolerance variations and ensure optimum stability.

• Parts: Available in quantities ranging from 1 to 1000 units, sinus washers can be purchased according to your specific requirements. Whether you need a single piece for a one-off project or several hundred for mass production, it's important to choose the right quantity.

• Line: Sinus washers are available in various lines, including stainless steel and carbon steel. Each line offers specific advantages in terms of strength, durability and cost, enabling you to choose the most suitable solution

How does a Sinus washer work ?

A sinus washer is a corrugated washer designed to offer controlled elasticity. Unlike flat washers, it has an undulating shape that enables it to generate a restoring force when compressed. This system is particularly useful for compensating for tolerance variations and absorbing vibrations in mechanical assemblies.

Sinus washers are generally made from stainless steel to guarantee excellent corrosion resistance and long service life. They are also available in plastic for specific applications requiring electrical insulation or reduced assembly weight.

Where can I find Sinus washers ?

Thanks to their unique design, they are used in a wide range of industries:

• Ball bearings: they optimize preload and improve bearing life.

• medical equipment: they guarantee the stability of sensitive instruments and reduce vibrations.

• Automotive industry: compensate for mechanical variations and improve assembly safety.

• Industrial machinery: they limit impact and extend component life.

Certain industries require washers that comply with specific standards (ISO, DIN, ASTM).

How to choose the best sinus washer ?

To choose the product best suited to your needs, consider several criteria:

• Material : examine your environment and choose between stainless steel (inox), plastic, steel...

• Check that all your equipment aligns perfectly (diameter, height, width, max and min thickness, end...) before proceeding with the assembly/disassembly of your parts (axle, spring, housing...)

• Take into account the conditions of use to which your equipment will be subjected: type of heat (high or low), applied load (axial or radial in kilo newton), maximum weight...
