Indexing, Ball and Spring Plungers, Thrust Pins, Quick Release and Locking Pins

When you need to align, hold, or latch different parts of equipment together, you need a spring loaded device. These components use the force in the spring to apply pressure so that the ball or nose will remain nested in some sort of hole or other receptacle. Thus two or more elements of equipment can be aligned or fixed into a determined relative position. Indexing plungers have a beveled or rounded nose that inserts easily into an indexing receptacle. Our indexing plungers include features like cam action, lock-out or non lock-out types, threaded bodies, weldable mounting flanges, long knobs, plate mounts, ring or L-handles, and more.

Ball plungers 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 they do not perform well with heavy loads. Our ball plungers include push-fit styles, threaded bodies, slotted heads, and more. Spring plungers have a nose designed to allow for movement when some side force is applied. In other words, it isn’t necessary (or possible) to retract the nose mechanically. Consequently, these plungers are not appropriate if heavy side load is involved in the application. Our spring plungers come in a variety of sizes and nose types.

Hand-retractable spring plungers are a sort of 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. Side thrust pins are designed for fixturing small parts and holding them in place with constant pressure. Quick release pins 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.
