The Jergens Delrin Tip / Stainless Steel Spring Plunger, part number 30515, features a single-unit construction that enhances reliability by eliminating the need for a set screw, which can loosen or separate from the plunger body. This design prevents lost springs and the need for "easy-out" tools during adjustments. The plunger is made from low carbon steel with a black oxide finish, and the tip is constructed from Delrin, providing durability and a close tolerance between the tip and body. The plunger conforms to TCMA dimensional standards and includes a patch-style locking element. It has a hex drive for easy insertion and is available in various force ratings, indicated by color coding: white for light force and blue for heavy force. Special materials and sizes can be requested to meet specific application needs. For optimal performance, the tapped hole should be countersunk slightly larger than the plunger's major diameter.
Jergens Spring Plungers, unlike conventional spring plungers, are machined in one piece. The spring is assembled from the top so that there is no need for a set screw. Our Spring Plungers do not have a set screw that can loosen or separate from the plunger body. The advantage is no lost springs and no need for “easy-out” tools. When adjusting Solid Drive, you can be sure the plunger body is turning and not a set screw.
