Part Number 68514476525, Curved Jaw Clamping Hub w/ Frictional Locking


Measurement and Control Systems
    The torsional stiffness of the GS Series coupling provides zero backlashes needed for the accuracy for measurement and control systems. The low torques of these applications give the GS Series the ability to provide zero backlashes due to the elastomeric pre-stress.
Servo and Positioning Drives
    The GS Series provides a zero backlash, flexible connection for servo and positioning drives. An added benefit of the GS Series is its damping capabilities.
    For applications that have vibrations at critical speeds, the GS Series coupling can provide a zero backlash solution for vibration problems.
Main Spindle Drives
    The GS Series coupling is used in main spindle drives for machine tools. Torque spikes and cyclical loading are handled by the GS Series by damping or by shifting the vibratory frequency range to a non-critical speed range.
The GS Series can be used in a variety of different applications requiring precision and accuracy.

The GS Series spider features a straight center of the spider tooth, providing higher stiffness due to coupling prestress. The crowning of the ends of the spider legs allows for misalignment, while the curved jaws and solid spider center provide high-speed capability.The jaws of the hubs and the spider legs are chamfered to provide easy assembly. The GS Series coupling design also allows the blind assembly in tight spaces. Raised spider dots on the legs of the spider ensure proper spacing of hubs and spider.

Proper installation of the coupling can provide isolation of electrical currents. Check the CL dimension listed on this page to ensure the proper spacing between spiders and hubs.

The GS Series coupling has spiders available in four different shore hardnesses. Each spider offers benefits for different vibratory, environmental, and torque transmission requirements.
