Tech Primer on Keyless Hub-to-Shaft Connections
Custom Machine & Tool Co., Inc, through 40 years of design and application experience in the synchronous drives market, saw a need for a technologically improved hub-to-shaft connection system.
CMT is a unique bushing attachment system: a single set screw locks the low-taper-angle split bushing in place and eliminates all of the existing attachment issues.
What is CMT?
A revolutionary new keyless tapered bushing, shaft to hub connection system.
Why Custom Machine & Tool Co Inc developed the CMT Bushing System.
As machine speeds and indexing requirements continue to increase reduction in inertia and vibration becomes important.
Bushing system is engineered to assure full surface contact and even clamping pressure without cocking with a single set screw.
