    Concentric Maxi Torque
    Patented Keyless Hub-to-Shaft Connection System

There Was A Need...

Engineers at Custom Machine and Tool Co., Inc. found that fasteners used to connect components to high speed shafts had to have lower intertia and create fewer vibrations.  We also knew that component alignment, accuracy, holding ability and runout became critical at higher speeds.  When no other company could offer a compact bushing for shafts less than an inch in diameter, CMT was up to the task. We decided to design, build and patent one. 

The result:  The Concentric Maxi Torque keyless hub-to-shaft connection system.
