Concentric Maxi Torque Bushing System in Custom Pulleys

Custom Machine and Tool Co. Inc.

CMT’s keyless hub to shaft connection device, the Concentric Maxi Torque, has superior features and benefits compared to other connection systems.

Innovative. The Concentric Maxi Torque system is a keyless hub to shaft connection solution.  It was designed and developed specifically to suit the hub to shaft connection needs of small shafts and drive components in
the motion control and power transmission markets. This patented  keyless hub to shaft connection system enables customers to easily phase, install, adjust and remove drive components, all while offering  precise component positioning.

Concentric. With radial runout  less than .001 /.26mm as assembled, the Concentric Maxi Torque system enables customers to attain higher drive speeds, reduce unwanted vibration and maintain concentricity, offering a superior connection solution.

Reliable. The mechanical shrink fit accomplished by the Concentric Maxi Torque system provides torque capacity which far exceeds that of two set screws arranged perpendicular to the shaft, offering the most reliable connection in the industry.

Economical. The compact design eliminates the need for the extended hubs used to accommodate  setscrews, allowing motion systems engineers to design drives which are lighter and use less space. Additionally, the shaft damage and added expense of shaft modification often associated with the use of set screws or pins is eliminated.

Versatile. The Concentric Maxi Torque system is currently being manufactured for synchronous belt drives in standard inch and metric pitches, for shaft sizes ranging from .125 in. (2mm) to 1.1875 in. (30mm). Other drive systems, including gears, sprockets, bearing assemblies, couplings, etc., will be quoted upon request.
