• There is no charge for use of the calculator.
• Prices provided are generally upheld; but are subject to review.
• It is your repsonsibility to assure that your application is safe and will function as planned. Use of the calculator does not guarantee that the springs you design will perform the way you expect them to, nor that they will be safe in your application.
• Terms such as "indefinite", "infinite", "fatigue", and "yield" are general descriptions intended to assist in comparing design alternatives and are not a guarantee of specific performance.

Over 14 Years, the design algorithms used by this calculator have been repeatedly confirmed in service and in fatigue tests. Still, there is no guarantee that any particular spring or design will work as anticipated. Indeed, it is to be expected that a certain percentage of the springs designed will not work as anticipated and may fail. This may be due to material imperfections, particulars of your application, normal manufacturing variability, misunderstanings regarding use of the calculator, and/or design nuances that may not have been fully understood (either by you, or by us). Use of the calculator is not a substitute for adequate product testing.
