High Load Disc Washers from China Factory - Reliable Suppliers for Compact Spring Applications

If you're searching for a reliable solution for high load applications in compact spaces, look no further than SMS Spring's Disc Washers, a top choice among China suppliers and factory offerings. These innovative conical washers are designed to support substantial loads while maintaining small deflections and compact heights, making them an excellent alternative to traditional helical springs. Disc Washers are particularly effective in addressing issues related to vibration, thermal expansion, relaxation, and bolt creep.

Manufactured from high-quality 300 Series Stainless Steel, SMS Spring's Standard Series Disc Washers are expertly crafted for durability and performance. Each washer is passivated in accordance with ASTM A967 specifications (superseding QQ-P35), ensuring the removal of contaminants and enhancing corrosion resistance. With slight magnetic properties, the 300 Series Stainless Steel is suitable for applications operating at temperatures up to 500°F (260°C). Trust SMS Spring, your premier China suppliers and factory for top-notch Disc Washers.

Product Details

📋 Description

The SMS Spring DIN Disc Washer Series offers metric disc spring washers to meet global demand for sizes specified by DIN 2093. SMS Spring also expand on size options past DIN 2093's standard size tables, made to DIN manufacturing and quality specifications to provide component flexibility for product designers. DIN Disc Washers are made with 51CrV4 spring steel (AISI 6150) and finished with a phosphate and oil surface for general protection from corrosion.

⚙️ Equipment Status

❑ A single Disc Washer has a specific load for a given deflection. Two washers stacked in parallel will yield double the load of a single washer for the same deflection; three washers will yield triple the load; four washers will yield four times the load, etc. Alternatively, two washers stacked in series will yield double the deflection of single washer for the same load; three washers will yield triple the deflection; four washers will yield four times the deflection, etc. Various series-parallel combinations therefore can provide a wide variety of combined results of load versus deflection for the stack. Consequently, depending upon the application, the designer can:

DIN Disc Washer Series designs are classified into three groups based on the material thickness (1)

Stack in "parallel" to increase load
Stack in "series" to increase deflection
Adjust the load and deflection of a washer stack by adding or removing individual washers and/or the sequence in which they are used, whether in series or parallel
SMS Spring Disc Washers are listed with calculated Loads at Flat. The Load Deflection Chart can be used to approximate intermediate loads.
Additional load flexibility can be achieved by stacking Disc Washers in various configurations. As shown in the diagrams above, Disc Washers can be used in four different ways.

🔩 Application

DIN Disc Washer Series designs are classified into three groups based on the material thickness (2)

Single: One Washer

DIN Disc Washer Series designs are classified into three groups based on the material thickness (3)

Parallel: All washers stacked the same way to increase load

DIN Disc Washer Series designs are classified into three groups based on the material thickness (4)

Series: All washers stacked opposite each other to increase deflection

DIN Disc Washer Series designs are classified into three groups based on the material thickness (5)

Series-Parallel: A combination of the two

❓ Frequently Asked Questions

Q What material are SMS Spring DIN Disc Washers made from?

SMS Spring DIN Disc Washers are manufactured using 51CrV4 spring steel (AISI 6150) and finished with a phosphate and oil surface coating to provide general protection against corrosion.

Q What standard do SMS Spring DIN Disc Washers conform to?

The SMS Spring DIN Disc Washer Series is designed to meet global demand for sizes specified by DIN 2093. SMS Spring also extends beyond the standard DIN 2093 size tables while maintaining DIN manufacturing and quality specifications.

Q How do I increase load capacity using disc washers?

To increase load capacity, stack disc washers in parallel — all oriented the same direction. Two washers in parallel produce double the load of a single washer for the same deflection, three yield triple the load, and so on.

Q How do I increase deflection using disc washers?

To increase deflection, stack disc washers in series — alternating the orientation of each washer. Two washers in series produce double the deflection of a single washer for the same load, three yield triple the deflection, and so on.

Q What are the three groups in the DIN Disc Washer Series and how are they classified?

The three groups are classified by material thickness: Group 1 covers washers with thickness less than 1.25mm (88 sizes); Group 2 covers 1.25mm to 6mm thickness (161 sizes); and Group 3 covers over 6mm to 14mm thickness (41 sizes).

Q Can disc washers be combined in series and parallel configurations together?

Yes. A series-parallel combination allows designers to fine-tune both load and deflection characteristics simultaneously. By adding or removing individual washers or changing the stacking sequence, a wide variety of load versus deflection outcomes can be achieved to suit specific application requirements.
