Delrin Tip / Steel Spring Plungers
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.
Features & Benefits:
-
Single-unit construction for better reliability
- No set screw to separate from the plunger body
-
No need for “easy-out” tools
-
Close tolerance between tip and body
-
Conforms to TCMA dimensional standards
-
Patch-style locking element
-
Hex drive in the rear for spring plunger insertion
-
Special materials and sizes available upon requests
Material Specifications:
-
Body Material: Low Carbon Steel
-
Body Finish: Black Oxide
-
Tip Material: Delrin
-
Thread: 2A-UNC
-
Plunger tips are color coded to indicate light or heavy force:
-
White: Delrin Tip, Light Force
-
Blue: Delrin Tip, Heavy Force
-
Note(s):
For easy insertion of Spring Plungers with locking elements, the tapped hole should be countersunk at least 0.030-0.045" (0.76mm-1.14mm) larger than the major diameter of the plunger.
