ST 928C
Precision bearing staking tool for point-retention bearing installation
ST 928C is a precision aerospace bearing staking tool for point-retention operations. It creates discrete staking points around bearing outer races to prevent rotation and axial movement. ST 928C is used when continuous swaging is not required or permitted by the engineering drawing.
Overview
ST 928C is a precision staking tool for aerospace bearing retention. It creates discrete staking points rather than continuous swage profiles.
Staking is used when the engineering drawing specifies point retention or when housing geometry prevents continuous swaging.
American Precision Assembly uses calibrated ST 928C tooling for bearing staking operations as specified by engineering requirements.
