Governed by the specifications outlined in the European DIN EN 16984/16983 (formerly DIN 2092/2093), American Belleville disc springs are engineered and manufactured to perform as needed in the most arduous dynamically loaded spring applications, where high load relative to available space is required.
Serrated Safety Washers (Anti-Vibration)
A range of serrated disc springs specifically designed to suit bolts and prevent loosening due to vibration. Made from both carbon steel and stainless steel.
These springs are conical spring washers that are able to achieve high loads with a very small deflection. The belleville springs also known as belleville washers are designed as per American standards for static or dynamic aplications where high spring loads are required. They are very useful in bolted assemblies where they are used to maintain the tension. Any aplication where it may be necesary to compensate relaxation, vibration or diferential thermal expansion are very indicated for these washers
It is possible to use these bellevilles as a single unit or also it is possible to use it in a stack. The stacks can be used in serie (increasing the deflection) or paralel (increasing the load). Finally, it is also possible to use a stack conbining serie and paralel bellevillles. Feel free to ask our engineers to design the best configuration that covers your requeriments.
Elastic disc springs are pieces with a great accuracy. Most of the sizes are standard as per DIN 2093. In any case all of them are manufactured meeting all the characteristics necessary to work in a dynamic way supporting a high number of cycles as a DIN 2093.
These conical springs provide an elastic axial strength proportional to deformation they suffer. Depending on your needs, it's possible to stack these springs in serial or in parallel to achieve the spring required. These springs are also commonly known as Belleville springs.
Belleville springs DIN 2093 made of stainless steel 1.4568 ( 17-7PH ). Designed to dynamic or static works as well. These springs made with this material has a good resistance to corrosion, so are able to work at inside or outdoor aplications.
cb manufactures disc springs, disc spring stacks and slotted disc springs. Special springs, wave springs, ball bearing disc springs and conical spring washers are also part of our portfolio. And not only that: for everything to do with vanes, rotors and complete Subassemblies for vane pumps, we are always the right address.
Over the course of more than 100 years, Smalley has been the industry leader and technological pioneer of retaining rings and constant section rings. And for more than 50 years, Smalley has been revolutionizing the industry with compact wave springs.
Disc springs are particularly suited for use in applications that require a high force but have limited space. By combining the springs in various ways, it is possible to obtain different forces and characteristics.

- General information about disc springs
Disc springs provide high spring forces while requiring only a small installation space. One of their advantages is the increase in spring forces and deflections thanks to the different layering of the individual springs in spring stacks. The fact that the load/deflection curve can be influenced in many areas by continuously adjusting the component geometry is also a big plus.
Belleville washers are designed to maintain a large amount of force with minimal deviation. This type of washer is utilized to reduce thermal expansion and vibration in commercial facilities. Belleville washers are helpful in applications with limited space and heavy loads. The washers in our catalog feature a high spring rate to meet your requirements. Our washers are engineered to create secure connections. We offer belleville washers in materials such as spring steel, bronze, low carbon steel, brass, and stainless steel.
This calculation will look at the force provided by a stack of belleville disk springs actuated by the instrument latches on the bottom of the Sloan 2.5m telescope. The goal is to determine the correct combination of springs in series and parallel to provide about 800 lbf at full deflection. The springs selected for the camera stirrup are Schnorr part number Z-12B, SWACO part number BS-1.102-0.500-1.25. Parameters are given below.
The drawing of the camera stirrup from Jim Gunn shows eight sets of springs in series. Each set is made up of two springs in parallel. This arrangement provides for the load of 972lbs when all of the sets of parallel springs are deflected by .026". The total deflection of the stack comes from multiplying the number of sets in series by the deflection.
This number is the additional extension that the screw should stick out from the bottom of the stirrup aftertightening from the condition with the latch latched and the bellevilles initially uncompressed.
The effective stroke of thelatch is only about 0.59". The bellevilles will still be under load when the latch has unlatched. What is the initial load of the belleville washers with the latch unlatched? I will assume that the full 75% deflection was the force while the latch is latched.
If 2 identical disc springs are inserted into each other, this provides 2 x the force and 1 x the travel.
If 2 identical disc springs are placed against each other, this provides 1 x the force and 2 x the travel.Therefore, by combining identical stacks, you can adjust the force and the travel according to the task.
Springs are dimensioned according to DIN 2093. The dimensions in the catalogue are unmachined measurements. Therefor measurements may differ from those in the catalogue tables. This applies to diameters and thickness.
