Belleville Disc Springs and Washers

We offer a line of DIN spec parts for applications when exacting tolerances are crucial. Our Belleville DIN and standard disc washers provide the same overall functionalities as DIN Spring washers. The only subtle difference is that a DIN washer is designed to metric standards, while a Belleville disc spring washer is available in standard spec sizes. Solon Disc Springs (SDS) are manufactured to ISO Certified standards and conform to the European standards DIN EN 16983 & DIN EN 16984* (formerly DIN 2092 & DIN 2093) and are RoHS compliant. DIN/SDS washers are available in standard metric sizes from 2.5mm - 125mm.

Belleville DIN and Disc Spring Washer Advantages

• Expert Manufacturing: All Solon Disc Springs are subject to exacting manufacturing and quality control standards. Additionally, all our DIN spec disc springs and Belleville disc spring washers are preset so that they will not significantly relax under load over time.
• High Quality Material: DIN & Disc Spring Washers are available in Carbon Steel, 17-7 PH Stainless Steel, 301 Stainless Steel and Inconel.
• Superior Finish: Carbon steel disc springs are finished with the standard corrosion protection of phosphate oil.
• Conical Design: Solon utilizes a conically shaped disc that deflects (flattens) at a given rate. Conical spring washers have a high spring rate, resolve thermal expansion and can produce extremely high loads in a small area.

DIN Spring & Disc Spring Features

Solon Belleville DIN and standard disc spring washers withstand extreme temperatures. American-made Belleville springs are effective when a large number of deflection cycles or forces are critical. Carbon steel disc springs are finished with phosphate oil for improved corrosion resistance in demanding environments. Whether you have a custom material specification or unique application challenges, Solon’s full-service design engineering and production teams can help you with your requirements. DIN/Disc Springs absorb shock, provide dampening, and support high tension in bolted applications.

Solon Manufacturing Co. is proud to contribute to the renewable energy industry by manufacturing Belleville springs and washers for hydrogen technologies and similar industries dedicated to reducing carbon dioxide emissions.

Din & Disc Spring Arrangements

We also provide a digital library of tools and resources to answer any additional questions about washer products.

Belleville Disc Spring Stacking Arrangements

When used singly or in stacks, Belleville DIN and disc washers provide numerous applicable advantages when a specific load or travel is desired. Belleville disc springs function positively within conditions that require very high load in confined space or short travel. Under these constraints, it is often not practical or even possible to use a coil spring. Some of the unique ways that Belleville washers can be arranged include:

• Single
• Parallel Stack
• Series Stack
• Parallel/Series Stacking
