The Concentric Maxi Torque connection system, with its mechanical shrink fit, offers tight runout control, precise component positioning and eliminates the need for secondary machinery. CMT’s patented bushing system will solve your most demanding hi-tech synchronous drive challenges and more.
WHAT IS THE CONCENTRIC MAXI TORQUE?
- CMT is a revolutionary keyless tapered bushing & shaft-to-hub connection system.
- Developed initially for the synchronous drives market.
- Designed and patented by Custom Machine & Tool Co., Inc.
- Patent No. 6,568,063
CMT TECHNOLOGY
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.
- Bushing system is engineered to assure full surface contact and even clamping pressure with a single set screw.
- Set screw size optimized to provide holding torque in line with shaft diameters and component torques.
- Developed using mathematical and FEA modeling.
- Scalable to any shaft/bore size requirement.
- Lower inertia and better shaft-to-component balance.
- System design assures near perfect hub-to-shaft concentricity when assembled.
