Koenig Sidex SK 552 Long Mandrel

PART NUMBER : SK 552

MATERIAL: Case Hardened Steel

Product Description

The Sidex SK plug works on the pull/expand principle. The plug consists of an expandable sleeve around a mandrel type expanding element. By applying an axial force to the mandrel while restraining the sleeve with a special tool, the sleeve is forced to radially expand, and the serrations on the outside of the sleeve anchor into the base material of the bore wall. Upon reaching a predetermined force, the mandrel breaks off and the plug is set.

The Sidex SK 552 differs from the SK 550 is that it is the long mandrel version

One piece construction, ideal for automated high production requirements.
