Gas springs are self-contained, force generating, maintenance-free cylinders. They are used to move and position lids, chairs, table-tops, and host of other assemblies. body is pre-charged with nitrogen gas to provide a specific output force. Pressure is applied to the piston and diameter area, which provides the output force in push-type gas springs.
Standard Gas Springs
Standard gas springs are quick and easy to order. They’re also relatively inexpensive, provided they don’t need troubleshooting right out of the box to fit the application. However, customers may underestimate how much data they need to specify gas springs. Furthermore, off-the-shelf gas springs commonly offer only one of three choices of output force. Will one of them be exactly right? There’s a good chance designers and customers may get unintended results.
If factory-supplied output forces don’t work, hoods or lids may open unexpectedly, or the spring might not support the load it needs to move. Another concern with off-the-shelf gas springs: customer drawings fail to allow room in the installation for the spring. Or, the spring comes with the wrong end fittings. These situations often force customers to waste time trying different forces and modifying the assembly, and they still may not get the right gas spring for the job. All this trial-and-error inflates labor costs and the project suffers needless delays.
Unlike most standard gas springs, an engineered spring is, in essence, a custom part the manufacturer typically adjusts to an application’s specifications. The added investment usually pays off via saved time and labor costs that come from gas springs working perfectly the first time.
