Carter Manufacturing released the new UNASIS Aerospace bearing cutting tool. Specially coated (using vapor deposition) with an exotic material which is significantly harder than tungsten carbide, it is designed for the challenges present in removing Inconel 718 bearings. Inconel 718 is a nickel-based precipitation-hardening alloy. Structures working with Inconel 718 bearings all know the limitations of currently available bearing removal tooling as well as the expense involved in frequently replacing cutting tools when these style bearings need to be removed or installed.
Carter’s new UNASIS tool is originally engineered for use both in and around the CFM56-B and V2500 engines but equally at home on other fitments. UNASIS is part of a complete kit including a tri-roller swaging tool, a specialist cutting tool, an installation and removal tool, a proof load test tool and breakaway torque tool. UNASIS tools can be specified for use with either a drill press or completely portable and hand-held, thus offering users significant operational flexibility.
