Description

Product description
Indexing plungers are used where any change in locking position due to lateral forces should be prevented. A new indexed position can be only be moved to after the pin has been manually retracted. Style C and D are recommended for applications where the indexing pin should remain disengaged for an extended period and be prevented from springing back.

Premium indexing plungers are characterized by higher manufacturing demands of the indexing plunger and the threaded sleeve. In addition, a centering locator has been added to the threaded sleeve, which can be used to increase positioning accuracy.
