Disc Springs
(Online Catalog)

• Precision manufactured with outside diameters ranging from 4 - 1000mm (0.157" - 39.37"), spring thickness from 0.1 - 60mm (0.004" - 2.36"), plus all standard and custom inch sizes.
• Available with linear, convex, concave or negative characteristics
• Used in dynamic, impacting or static load applications - depending on customer requirements.
• Capable of many millions of cycles - depending on type of use.
• Complete predictability of force.
• Occupy less space for equivalent forces compared to other spring designs.
• Excellent permanent spring performance from low to elevated temperatures (from -400°F to +1500°F) by selecting appropriate spring materials (steel or others).
• Adaptable to stacking in numerous configurations (stacks).
• Manufactured to the very rigid DIN 2092 and 2093 disc spring specifications (equivalent ASME, SAE or ASTM specification not available).
  

Why use Disc Springs?

• The spring characteristic (linear, positive or negative) can be engineered to a large extent by means of changing the disc spring properties (dimensions, adding slots on inside or outside, stacking, etc.)
• Very slight spring deflections can be achieved by use of single springs.
• Using disc springs in series, spring deflection increases, without materially affecting the forces involved.
• They can be combined into groups of serial and parallel order in the same stack for special applications.
• Disc springs show a symmetrical buildup of forces around the rotating axis, with this symmetry being maintained throughout the lines of the spring equally.
• They show a circular, symmetrical transmission of forces in the exact direction of the spring axis - this being directly in contrast to actions of coil springs.
• They permit the use of the smallest possible
  working area - this being notably in contrast to the space required to accommodate the "dead windings" of a coil spring.
• Disc springs are characterized by high forces resulting from moderate spring deflections - in direct contrast to other spring types.
  Applications.

Here are a few examples of applications with disc springs in use:

• Control Valve
• Safety Valve
• Automatic Quick Tool Changer (CNC Machines, etc.)
• Torque Converter
• Clutches Manual Transmission
• Nozzle of Spray Injection Molding Unit
• Brake System
• Brake Slack Adjuster
• Stamping Machine
• Damper
• Over Load Protection
• Etc.
