What our customers are saying.


"The way your gears and locking system works has made my job much easier.  I had a test run last night to 5000 rpm, a full double what I expect to use the system at and everything went smooth and I was pleasantly surprised on how smooth the belt ran with your gears on it."


"The control of the stepper motor to the flywheel was perfect.  The belt ran smooth without any noise or vibration.  I can't be happier with the way things are coming together."

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.
