Steel Ball Plungers - Fine Thread (UNF)
Jergens Ball Plungers are made under extremely accurate machine controls and rigid inspection procedures. Accurate spring alignment is maintained by using a stainless rivet with a long shank on larger sizes of our Ball Plungers. This precisely positions the spring for more accurate ball travel and provides positive control of spring pressure. By minimizing the lining pin head thickness, we are able to use the longest possible springs. Features & Benefits:
Positive control of spring pressure
Less fatigue and longer spring life by minimizing lining pin head thickness
Uniform ball projection keeps variances within ±0.005".
Conforms to TCMA dimensional standards
Patch-style locking element
Special materials and sizes available upon requests
Material Specifications:
Body Material: Low Carbon Steel
Ball Material: 440 Stainless Steel
Spring Material: 17-7 PH Stainless Steel
Body Finish: Black Oxide
Thread: Inch: 2A-UNF
Note(s): For easy insertion of Ball 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.
