Description

DIN 2093 Disc Springs (Disc Washers)

The DIN 2093 Disc Springs manufactured by Raleigh Spring are engineered to provide high load capacity within limited installation space. Manufactured in accordance with DIN EN 16983 (formerly DIN 2093) standards, these conical spring washers offer outstanding performance in static and dynamic applications, making them ideal for machinery, automotive, heavy equipment, industrial automation, valves, and power transmission systems.

With extensive manufacturing capabilities, Raleigh Spring supplies both standard metric disc springs and customized solutions to meet specific application requirements.

Product Features

High Load Capacity in Compact Spaces

Disc springs generate extremely high spring forces with minimal deflection, making them an excellent solution for applications where axial installation space is limited.

Excellent Shock Absorption

The conical design effectively absorbs vibration and impact loads, helping to protect mechanical components and improve equipment reliability.

Variable Spring Characteristics

Different stacking configurations provide different load-deflection characteristics, allowing engineers to customize spring performance for various operating conditions.

Suitable for Static and Dynamic Loads

Designed for both continuous static loading and high-cycle fatigue applications, disc springs offer long service life and stable performance.

Flexible Stacking Options

Disc springs can be assembled individually or stacked in various combinations to achieve different spring forces and working strokes.

Typical configurations include:

  • Single disc spring

  • Parallel stacking (higher load capacity)

  • Series stacking (greater deflection)

  • Combined parallel and series arrangements

Available Product Range

Raleigh Spring manufactures a complete range of DIN 2093 Metric Disc Springs, with additional custom sizes available upon request.

Disc Spring Groups

Group Thickness (t) Flat Bearing Surface
Group 1 ＜1.25 mm No
Group 2 1.25–6 mm No
Group 3 6–14 mm Yes

Assembly Recommendations

Correct installation is essential for achieving optimum spring performance and service life.

During assembly:

  • The disc spring contacting the supporting surface should be supported by its outer edge whenever possible.

  • Proper support reduces contact pressure and minimizes the risk of fatigue cracking.

  • Guide rods (internal guidance) or guide bushes (external guidance) are recommended to ensure stable operation.

Recommended Guide Clearance

Inner Diameter / Outer Diameter Recommended Gap
≤16 mm 0.2 mm
>16–20 mm 0.3 mm
>20–26 mm 0.4 mm
>26–31.5 mm 0.5 mm
>31.5–50 mm 0.6 mm
>50–80 mm 0.8 mm
>80–140 mm 1.0 mm
>140–250 mm 1.6 mm
>250 mm 2.0 mm
