High Load Disc Washers from China Suppliers - Durable Solutions from Our Trusted Factory

When you need to handle high loads in compact spaces, consider SMS Spring's Disc Washers, ideal solutions from a trusted China supplier. Their unique conical design allows for exceptional load-bearing capabilities with minimal deflection and low overall height, making them a superior choice compared to traditional helical springs. These high-performance Disc Washers are commonly utilized to address issues such as vibration, thermal expansion, relaxation, and bolt creep.

Manufactured in our state-of-the-art factory, SMS Spring's Standard Series Disc Washers are crafted from premium 300 Series Stainless Steel. Each washer is passivated to ASTM A967 specifications (superseding QQ-P3to eliminate contaminants and enhance corrosion resistance. This grade of stainless steel is slightly magnetic and is recommended for applications where operating temperatures can reach up to 500°F (260°C). Trust in SMS Spring as your go-to supplier for Disc Washers that meet stringent quality standards.

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.

Programing

Group 1

This range applies to disc spring washers with material thickness less than 1.25mm. SMS Spring DIN Disc Washer Series include 88 sizes in Group 1, over a selection of outside diameters from 6mm (0.236") to 40mm (1.575") with inside diameters from 3.2mm (0.126") to 20.4mm (0.803").

Group 2

This range applies to disc spring washers with material thickness from 1.25mm through 6mm. SMS Spring DIN Disc Washer Series include 161 sizes in Group 2, over a selection of outside diameters from 20mm (0.787") to 200mm (7.874") with inside diameters from 10.2mm (0.402") to 102mm (4.016").

Group 3

This range applies to disc spring washers with material thickness over 6mm through 14mm. SMS Spring DIN Disc Washer Series include 41 sizes in Group 3, over a selection of outside diameters from 100mm (3.937") to 250mm (9.843") with inside diameters from 51mm (2.008") to 127mm (5.000").

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 (FAQ)

What material are SMS Spring DIN Disc Washers made from?

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

What standard do SMS Spring DIN Disc Washers conform to?

The SMS Spring DIN Disc Washer Series is designed to meet sizes specified by DIN 2093. SMS Spring also expands on size options beyond DIN 2093's standard size tables while maintaining DIN manufacturing and quality specifications.

How can I increase load capacity using DIN Disc Washers?

You can increase load capacity by stacking washers in parallel — all washers oriented in the same direction. Two washers in parallel will double the load; three will triple it, and so on for the same deflection.

How can I increase deflection using DIN Disc Washers?

Stacking washers in series — all washers oriented opposite each other — increases deflection. Two washers in series double the deflection for the same load; three washers triple the deflection, etc.

What are the three groups of SMS Spring DIN Disc Washers?

Group 1 covers washers with material thickness less than 1.25mm (88 sizes); Group 2 covers 1.25mm to 6mm thickness (161 sizes); Group 3 covers 6mm to 14mm thickness (41 sizes). Each group offers different outside and inside diameter ranges to suit various applications.

Can DIN Disc Washers be combined in series-parallel configurations?

Yes. Series-parallel combinations allow designers to fine-tune both load and deflection characteristics. By adjusting the number of washers and the sequence in which they are stacked, a wide range of load-deflection results can be achieved for specific application requirements.
