The following considerations will help you solve the problem above: Imagine you have a spring whose free length is 5 inches and the spring rate is 7. With that in mind, hold the following in high esteem. Helical Compression Springs The theoretical load of helical compression springs can be determined by knowing the outer diameter, free length, wire diameter, and the number of coils. Tension and Extension Springs The theoretical load of tension and extension springs can be determined by considering the outer diameter, wire diameter, length of the body, length inside the hook, and the type of hook used.

Torsion Springs When it comes to torsion springs, you need to measure the number of coils, wire diameter, length of legs 1 and 2, outer diameter, and any bends or shapes on the legs. The calipers can be held in one hand while the base of the spring is held with the other hand. Conclusion These are the important details to understand when it comes to spring load and its relation to spring rate.

Necessary Necessary. Functional Functional. Performance Performance. They are used in workholding applications, as well as for indexing, latching, ejecting, and even electrical contacts. These have a beveled or rounded nose that inserts easily into an indexing receptacle.

The nose is long enough to fix the position firmly, preventing movement in any direction. In order to move the position of the plunger, the operator must mechanically retract the nose. An example is this GN indexing plunger non-lock out type. Spring plungers differ from indexing plungers in that they have a nose designed to allow for movement when some side force is applied. Consequently, these plungers are not appropriate if heavy side load is involved in the application. Shown is our SPNL short spring plunger note the nylon locking element in the side of the threaded body.

These plungers are sort of a hybrid of the two above types, and include a knob for manual retraction of the plunger. Among other things, they are used for manual or automated holding, as in workholding applications. Here you see our LRSS stainless steel hand retractable spring plunger lock out type.

These have a ball instead of a nose, and no knob. The shallow depth of the ball allows for easy movement in and out of position, but as with spring plungers, they do not perform well with heavy loads.

The illustration is our GN steel ball plunger with threaded body note the slot provided for installation with a screwdriver. These components are designed for fixturing small parts and holding them in place with constant pressure, as shown in the illustration. In the photo you see the GN zinc-plated steel side thrust pin, which has a threaded body.

Quick release pins: Instead of body with a nose, these components consist of a rod or stem, from which small side securing pins protrude. A button in the handle retracts or extends these pins so that the quick release pin can be removed or secured in place see application example to left. The component in the illustration is our GN We offer many other options for quick release pins, including stainless steel components, heavy duty construction, and self-locking features.

So far your choices seem fairly simple--along with, of course, selecting the proper size we offer these types of components in many sizes, both inch and metric. But there are more options than that to consider. Balls, as mentioned above, allow for easy position changes. However, their holding force is limited.

Noses may be round for reduced friction and similar easy positioning. They can also be chamfered for easier insertion into indexing holes. Flat noses have a larger contact area but will obviously resist side motion. Hex noses can allow installation of the plunger from the front with a hex wrench, but are subject to faster wear. The material chosen for the ball or nose is also key: case hardened steel noses are strong and heat-resistant, but can mar the surface to which they press.

Phenolic plastic is an economical option but is more brittle. Stainless steel is the best choice for sterile applications. The body of a plunger varies depending upon installation considerations.

It may be threaded, it may have a lock nut for securing the mounting see illustration. Or it might be smooth for push-fit installation, or smooth and weldable. Threaded body plungers may have a locking element or patch. Torsion springs act differently than compression or extension springs. The coils of torsion spring appear to be fully compressed with straight ends of the coil sticking out on either side. When one end of the torsion spring is fixed and the other rotated, the coil begins to deform which creates a force opposing that rotation.

As the name dictates, these mechanisms deliver a near constant force. Constant force springs are thin, rolled sheets of metal with a drum or shaft in the center. The drum or shaft serves to keep the geometry of the coil nearly constant resulting in a nearly constant force since the majority of the force opposing motion is stored in the coil.
