CD Couplings allow you to transmit high torque in a small envelope. They are ideal for cyclic applications where speed and repeatable accuracy are critical to keep 24/7 systems going. CD Couplings withstand the punishment and stress of a servo motor. In comparison, other couplings may have high torsional stiffness specifications; however, they can be too brittle to withstand the punishment of high speed reversing applications and shaft misalignments. Standard and Custom CD Couplings are available for every application. Do you need higher misalignment and greater torque capacity in your coupling?...

CD® Couplings Single Flex Steel The Single Flex Composite Disc Coupling is an excellent choice for zero backlash applications. The unique design delivers two features that are not often found in a precision coupling. High torsional stiffness and high durability! The compact size and clamping system allow this coupling to fit into many applications. This design is also capable of being used in very high speed applications with slight modifications. • Zero Backlash • Torsionally Stiff • Excellent for Reversing Loads • Smooth Operation at High Speeds Available with or without keyway on clamp style...

Single Flex Steel Dimensional Information Performance Note: The torque capacity of keyless clamped hubs is governed by many factors, including shaft/hub bore diameter, clamp size, and other installation variables. Keyless coupling hubs with smaller bore sizes (approximately less than one-half the maximum bore listed) may not transmit the full torque rating of the coupling. Consult factory for further detail if your application is of high torque/small keyless shaft variety.
