HistoryCustom Machine & Tool & Co., Inc., (CMT) is a manufacturer of timing pulleys, drive systems and components for the motion control and power transmission markets in operation since 1964. CMT developed and patented a new and revolutionary hub-to-shaft connection device, allowing for precise component positioning and tight run out control on demanding applications. A the same time, it is easy to install and remove and is economical to manufacture. Our keyless hub-to-shaft connection device has superior features and benefits compared to other connection system such as keyways, pins, set screws, clamp collars, and other tapered shaft locking devices. The new system, called Concentric Maxi Torque, is available for immediate inclusion in our full offering of timing belt pulleys and can be designed into any custom application.SpecialtiesCustom synchronous drives, timing pulley stock, keyless tapered bushing system
