Ball and Spring Plungers

Ball and Spring Plungers are devices that enclose a spring in a threaded capsule and provide a means of applying accurate and repeatable spring end forces through a ball or rounded nose. Also known as Spring Loaded Devices, the unique features of ball and spring plungers make them essential components in thousands of applications for indexing, positioning, fixturing, latching, locking, ejecting, electrical contacts and many others.

Encapsulating the spring inside the body has several advantages over standard, unprotected springs: installation is fast and easy, side forces can be applied to the assembly and repeatable end forces and extension are maintained throughout the life of the plunger.

Most installations can be done with a screwdriver, but care must be taken since the body is hollow and does not have the strength of a bolt or screw.

Specifications:

  • Body made from steel, stainless steel or brass
  • Ball and plunger are steel, stainless steel or nylon
  • Spring is piano wire or stainless steel wire
  • Light, Standard and Heavy end forces
  • 4-48 to 1-8 threads available
  • Optional nylon locking element for locking body in place
  • Custom sizes, forces and materials available per request

Hand Retractable Spring Plungers

Hand Retractable Spring Plungers are precision machined from solid bar stock. The retractable plunger is hardened for greater side load strength in the extended position and is slightly tapered for easy alignment. All hand styles are easy to grip for fast one handed operation. With a 90 degree turn of the handle, the locking types will lock the plunger in the retracted position.

Hand retractable plungers have many industrial, medical and consumer applications and are commonly used as indexing, positioning, and fastening components. Their quick disconnect and positive locking features are ideal for sports and recreational equipment.

Specifications:

  • Body, handle and plunger are steel, stainless steel or brass
  • Spring is piano wire or stainless steel wire
  • CNC machined from solid bar stock
