Spring Washer - Overview

A spring washer is a type of washer designed to provide a spring force and maintain tension in a bolted joint. It's often used to prevent loosening due to vibration or thermal expansion and contraction. Unlike plain washers, which are flat, spring washers have a curved or conical shape that allows them to compress and exert a force when tightened.

Advantages of Spring Washer

Secure Fastening

Keep your nuts, bolts, screws and other hardware fasteners in place while reducing the risk of loosening or failure over time.

Increased Longevity

Distribute loads more evenly across the joint and reduce stress on the fastener. Spring washers increase the lifespan of your hardware and reduce the need for replacement.

Improved Vibration Resistance

The design of steel spring washers allows them to absorb and distribute forces, making them especially useful for machines and equipment with a high degree of vibration and shock.

Increased Safety

Critical components have a reduced risk of failure when their hardware is securely fastened. Spring washers exert a constant force on your fasteners to keep them from loosening.

Cost-Effectiveness

Spring washers are a relatively low-cost component, making them a cheap, effective choice for many different types of applications.

Types of Spring Washer

Belleville Washers

Also known as conical or disc spring washers, belleville washers provide the greatest load‑bearing capacity for their size. They compensate for expanding and contracting joints, span holes, and maintain high tension in screw and nut assemblies. By combining them in varying sequence, each size gives numerous load carrying possibilities.

Curved Washers

Also known as single wave spring washers or cylindrically curved washers, curved washers exert relatively light thrust loads and are often used to absorb axial end play or as lock washers for fasteners. The height of the form and material thickness are variables which can be adapted to a specific load/deflection function.

Finger Washers

Finger washers counteract excess wear, vibration, noise, and end play. They promote efficiency and smooth operation, reducing skidding wear on rotating elements. They are also extremely useful in cases of unavoidable loose internal clearances due to special application conditions. They are frequently used for preloading ball bearings and general applications.

Wave Washers

Also known as waveform washers, wave spring washers provide greater load‑bearing capability because of their three‑point contact and sharper curves. They are typically used in thrust‑loading applications for small deflections, particularly where radial space is limited. Applied loads are evenly distributed and there are no sharp edges to interfere or gall. The height and material thickness regulate the load function.

FAQ

Q: What is the ISO standard for spring washers?

A: ISO 7089/7090: These international standards specify the dimensions and mechanical properties of plain washers, ensuring consistency and interchangeability. DIN 6796: This German standard specifies the characteristics of conical spring washers for bolted connections.

Q: What material is used for spring washers?

A: Steel is the most common material for spring washers due to its ease of process and its high tensile strength. Chrome vandium alloy is a higher quality steel with a good through-hardening capability; it is used to make very thick spring washers.

Q: Do spring washers prevent loosening?

A: They are designed to provide a spring force and absorb shock by providing an axial load that counters vibrations. As a result, spring washers can drastically prevent fasteners from loosening over time.

Q: Can you stack spring washers?

A: Disc springs can be stacked in parallel or in series, and the orientation of each washer matters. Stacking in parallel increases the load capacity, while stacking in series increases the deflection. The arrangement should align with the application's load and deflection requirements.

Q: Are you manufacturer or trading company?

A: We are manufacturer.

Q: What's your best delivery time?

A: Within 15-30 days.

Q: What is the quality control of your product?

A: Follow strictly quality control measures for implementation,

Q: Will your company provide free sample?

A: It depends on which sort of item you want to get. Some can be provided free of charge, however, the client shall assume the shipping fees himself.

Q: Is OEM open to clients?

A: Yes, we can provide both OEM and ODM service.

Q: How can our company be your distribution partner?

A: We welcome you to be our distributor. For further details, please contact us.

Q: What is the payment of sample?

A: T/T and Alipay both acceptable.

Q: What is your sample policy?

A: If we have stock, we can provide samples, but the customer must pay the sample fee and express fee Question.

Q: Have you tested all your goods before shipment?

A: Yes, we will conduct 100% test before delivery, and we will send detailed photos of parts for your approval Question.
