Product description

Information

Ball plungers GN 615.3 are used as locating devices, detent pins, pressure pins and ejectors. A typical example is push-on / push-off applications.

Ball plungers mounted in various control levers are also perfect solutions for snap-indexing mechanism applications.

The hex socket end makes these plungers slightly longer than the ball plunger GN 615 with slot. In all other aspects they are identical.

The PFB (Polyamide) patch types are a thread jamming material which also provides some antivibration properties to hold the ball plungers in place. The coating for type K or KN (standard spring load) is indicated in blue, for type KS or KSN (high spring load) in green. For this type of thread locking, a relatively high torque is required. Therefore, this version with internal hex is more preferable than the version with a slot (GN 615).

MVK (Micro encapsulation precote) is a type of a thread locking glue (indicated in red) that surrounds the circumference of the threaded body as shown.
