High-Misalignment Series Swaged Bearing Proof Cups Kit

This high-quality tool set is designed for proof-testing the installation of certain spherical bearings which have a groove on either face of the outer race ("Grumman groove"). Each set includes a housing support cup, a bearing arbor, and centering mandrel.

After swaging your bearing in place, assemble the tools around your bearing and use your hydraulic press to apply the design load to the bearing. If the bearing moves axially beyond design limits, you may need to increase the force applied in the swaging process.

These tools are specifically designed to fit certain SAE-sized "high-misalignment" spherical bearings with a staking groove on either side of the outer race (Aurora HAB-xTG, Pegasus 3072-xG, or NHBB ABYT-xV or ADBYxV). When done properly, the installation should meet NAS 0331 Method 100 and MIL-STD-1999 requirements. Made in USA.

Note: Consult the bearing manufacturer, MIL-STD-1599 Notice 2, and/or NAS 0331 for specifics regarding suggested bore size and chamfer, swaging force, and final inspection.
