Terms of Sale
With respect to goods purchased by Buyer from Seller (“Goods”), no contract exists until Buyer places order for delivery and such order is accepted by Seller's acknowledging receipt of the order, by Seller's commencement of work on the Goods ordered, or by Seller's shipment of the Goods, whichever occurs first. Any acceptance will be limited to the express terms contained on the face hereof. Additional or different terms in Buyer's form or any attempt by Buyer to vary in any degree any of the terms of this quotation shall be deemed material and are objected to and rejected, but this shall not prevent the formation of a contract between Buyer and Seller unless such variances are in the terms of the description, quantity, price or delivery schedule of the goods, and the order shall be deemed accepted by Seller without said additional or different terms.
All agreements are contingent upon strikes, accidents and other reasons for delay beyond Seller's control
Where a separate charge is made for specially designed tools and dies, Seller will maintain such tools and dies without further cost to Buyer for the life of such tool or die so long as the part remains active and the design is not changed and Seller will not use such tools and dies for others without Buyer's permission, but Buyer acquires no right to remove any such tools or dies from Seller's factory.
Seller warrants to Buyer that the Goods purchased by Buyer from Seller shall be free from defects in material and workmanship. This warranty is the only warranty applicable to the Goods. THERE ARE NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE WHICH ARE HEREBY DISCLAIMED.
All Goods shall be inspected by Buyer when received and Seller shall not be liable for any defect unless notified in writing within 60 days after delivery.
Seller's liability for breach of warranty shall be limited solely and exclusively to repairing or replacing, at Seller's option, the defective Goods. In no event shall the liability of Seller for breach of any contractual provision relating to the Goods exceed the purchase price of the Goods quoted herein. In no event shall Seller be liable for any special, incidental or consequential damages arising out of Buyer's use or sale of the Goods or Seller's breach of any contractual provisions relating to the Goods, including but not limited to any loss of profits or production by Buyer. Any action resulting from any breach by Seller must be commenced within one year after the cause of action accrued.
Except to the extent caused by Seller's breach of warranty, Buyer shall indemnify and hold harmless Seller, its employees, officers and directors, and their respective successors and assigns, (collectively, “Indemnities”) from and against any and all liability, damages, claims, causes of action, losses, costs and expenses (including attorneys' fees) of any kind (collectively, “Damages”) arising out of injuries to any person (including death) or damage to any property caused by or related to the Goods or any negligent act or omission of Buyer, its employees or agents. Buyer shall indemnify and hold harmless each of the Indemnities from and against any and all Damages, royalties and license fees arising from or for infringement of any patent by reason of any sale or use of the Goods or the manufacture of the Goods to Buyer's specifications or sample. Upon the tendering of any of the foregoing suits or claims to Buyer, Buyer shall defend the same at Buyer's expense. The foregoing obligations of Buyer shall apply whether Seller or Buyer defends such suits or claim.
Seller reserves the right to over and under ship by not more than 10% of specified quantity.
Small quantities are considered prototype quantities and cannot be returned since the cost of re-inspecting and handling them is generally higher than the value of the parts. Larger quantities may not be returnable depending on the ability to re-sell these parts within a reasonable time period. Special runs are not returnable. All returns must be authorized and an Authorization Number is required. Please contact our Customer Service at email@example.com or by phone at 419-891-9292. Unauthorized returns will be returned at customer's expense. All authorized returns must be in their original packaging and labeling to insure lot control integrity.

Integrated System, "Black Box"
If your OEM application requires something to get it working, either a single part or sub-assembly, and you need assistance designing and validating this, Associated Spring RAYMOND can assist you. Simply let us know as many details as possible about the functional requirements so our engineers can understand the application. The "Black Box" approach means our experienced team does the work, designing, specifying, manufacturing, & validating. If you need a confidentiality agreement we routinely sign bi-lateral agreements to protect sensitive information. Through this process our engineers have assisted OEM engineers develop & bring to market great product advancements as well as completely new products.
Pre-load refers to a state of a spring in a cyclical application. When the spring cycles in the application it goes from its longest length/tallest height to the shortest length/height. The point with the longest length/tallest height in the application will determine the "pre-load". This refers to the loading of the spring at this point. For optimal life the pre-load needs to be matched carefully to the shortest length/height, but in general the spring should not be allowed to return to the free length/height in a cyclical application. This is because the change in stresses between the operating extremes will be significantly increased when using the free state of the spring instead of a "pre-load". Associated Spring RAYMOND engineer's can help minimize stresses to maximize life for your OEM application, simply contact us.
Stacking Disc Springs
Disc Springs are both components and modular systems, as they can be used individually or as a set of parts. Associated Spring RAYMOND offers the widest variety of disc springs, including Clover®Dome. Stacking parts allows for an infinite number of force-deflection curves. In general there are two directions to stack parts (although both can be combined). Parts stacked in series are placed in alternating orientations, and offer N x the deflection for the same load as one part, where N is the number of parts in the stack. Parts stacked in parallel are placed in the same orientation, and offer N x the force for the same deflection, where N is the number of parts in the stack. Associated Spring RAYMOND engineers can help to define a complete stack for your OEM application, simply contact us.
Corrosion is damage to materials, rust on steel is an example of corrosion. The level of corrosion protection required is application specific, and the type of corrosion will also vary. Carbon Steels (Music Wire, Spring Steel, Chrome Vanadium, etc.) without a coating are the least protected. Stainless Steels & Exotic Alloys offer protection from various agents. Coatings offer a means to supplement corrosion protection without changing materials. In some cases changing materials is not possible because of the forces, stresses, or other design parameters required by the application. In this case selecting a coating for parts may be the only option to achieve the desired part life. Coatings may also be more cost effective than substituting material. Associated Spring RAYMOND engineers can help to define the best material & coating for your OEM application, simply contact us. Standard parts can also easily be coated with most coatings.
Stress Levels Cause Spring Failures
Stresses in materials are one source of failure for springs. Reducing stresses is always optimal in designs where possible. Some ways to reduce stress (assuming everything else is held constant in the design) include:
- Use a thicker material or larger wire diameter
- Use a larger spring (larger outer diameter)
- Increase the pre-load of the spring (cyclical)
- Decrease the maximum deflection (cyclical)
- Reduce the amount of deflection in the application (Static)
Additionally the life of a spring can be extended with the same conditions/parameters with the following:
- Changing the material or alloy
- Special Heat Treatment Processes
- Advanced surface finishing processes"

DFARS Certified Material
DFARs or Defense Federal Acquisition Regulation Supplement, is a regulation the DOD or Department of Defense purchases materials in accordance with. As it pertains to material sourcing, specialty metals must be purchased from a US source or authorized source. Unfortunately, at this time, Associated Spring RAYMOND’s global manufacturing presence restricts its ability to commit to DFARS 252.225-7014 Alternate I on standard products.
If, after further review, you determine that your product must conform to DFARS 252.225-7014 Alternate I, please contact us for a special order at 1-800-228-1156. When inquiring, please ensure that your paperwork clearly indicates the DFARS 252.225-7014 Alternate I requirement. Once we receive your inquiry, we will evaluate them on a case-by-case basis and respond as quickly as possible to custom manufacture your product.
Proper Orientation of Gas Struts (Gas Springs)
Gas struts and dampers have seals. In order for the seal life to be as designed the struts must be installed in the proper orientation. For whichever position is most often occurring in the application, the rod end of the strut should be installed lower that the body. This helps keep oil on the seal for lubrication purposes. For example if a hood spends most of the time closed, it is important the rod be lower than the body in the closed position.
Differences between a Gas Strut (Gas Spring) & a Hydraulic Damper
Certain strut types are often confused. Gas struts, sometimes referred to as gas springs or gas shocks, provide a force. Dampers on the other hand only provide a reactionary force to slow motion. For example a damper would prevent a lid from lowering quickly, where as a gas strut could be used to push a lid up.
Installation & Removal of Gas Struts (Gas Springs)
Installing or Removing Gas Struts is typically very simple. Any anti-removal/safety devices, like a safety clip or circlip must be first removed. Then typically the ends simply pull off. For a video demonstration of strut installation & removal from various end fittings see this video: http://www.youtube.com/watch?v=Tki45RTWZnM
Matching Struts & Accessories
Struts (Gas Struts, Dampers, etc.) often utilize mounting hardware. Typically the ends of struts are threaded, and may or may not be supplied with end fittings mounted on the threads. End fittings can be exchanged with another end fitting with the same thread. M6, M8, & M10 threads (male) are common strut threads. End fittings must have a mating thread, typically female, of the same size. Mounting a strut with end fittings already installed depends on the type of end fitting. End fittings are typically designed to be used with a ball stud (most common) or shoulder bolt. For ball stud end fittings as long as the ball size is the same on the end fitting and the ball stud or bracket the pair is compatible.

Generally springs have an acceptable deflection range, meaning the spring will work properly if the deflections from the resting length or height are kept less than or equal to the operating range. When deflections exceed the maximum operating deflection the life of the spring will be reduced, sometimes drastically. It is possible to design a different spring with a greater operating deflection range by changing various parameters of the design.
Operating Temperature Range
Generally springs, struts, dampers, and other products have an acceptable operating temperature range. This range is dependent upon the materials used in construction, including any seals. Higher range materials are generally available for special applications requiring such, but typically cost more.
