Adding Value to a Spring Through Encapsulation
A Spring-Loaded Device (SLD), Enhanced Spring or Spring Plunger is a device that adds value to a spring by encapsulating it in a body and providing a plunger tip or ball on one end—enabling accurate and repeatable end forces.
Not a bolt or a screw, a spring-loaded device should not be subjected to the same installation or fastening forces common with bolts and screws. An SLD does not have the head size of a screw or bolt and it has a (hollow) threaded or push-fit style body in order to encapsulate a spring.
Vlier highly recommends that you read the SLD Installation section before designing SLDs into your product or fixture.
Vlier spring-loaded devices fall into four main categories:
- Standard Spring Plungers Stubby Spring Plungers Ball Plungers
- Quick Release Plungers
