High Speed Pedestal Mount Double Flex Shrink Disk Couplings

High Speed Pedestal Mount

50 Nm to 5K Nm
442 lbf-in to 44K lbf-in

High Speed Pedestal Mount Double Flex Shrink Disk Couplings are engineered for fixed torque transducer installations that demand exceptional torsional rigidity, precision, and reliable performance at elevated rotational speeds. Featuring double-flex disc packs, these couplings accommodate angular, parallel, and axial shaft misalignment while minimizing reaction forces that could affect measurement accuracy. The shrink disk hub design provides a secure, backlash-free connection to smooth shafts without the need for keyways, ensuring excellent concentricity and high torque transmission. Their low-inertia, maintenance-free construction helps reduce vibration and supports smooth operation in demanding test stands, dynamometers, production equipment, and industrial automation systems. Designed for high-speed applications, these couplings deliver dependable power transmission while protecting sensitive torque transducers from unnecessary loading, resulting in accurate, repeatable measurements and long service life. These couplings are available for the following torque sensor:

  • T25 High Speed Shaft Style Rotary Torque Transducer – 50 – 5k Nm (442 to 44.2K lbf-in)

Floating Mount Single Flex Couplings are designed for free-floating torque transducer assemblies, providing a torsionally stiff connection while minimizing unwanted loads on the sensor.
