Description
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.

Elastomer Characteristic
- Four types of spiders are available for the CJ Series of couplings
- Urethane spiders provide high abrasion resistance and elasticity, along with good damping characteristics
- The spiders are offered in a variety of shore hard nesses, each providing a different level of torque capacity, damping, and chemical resistance
- The 92A shore insert (yellow in color) is the standard, offering excellent torque carrying capacity
- The 80A shore insert (blue) offers the best damping characteristics
- The 95/98A shore spider (red) offers higher torque than the standard 92 shore, but retains greater damping capacity compared to the 64D shore insert (green)
- The 64D shore insert is offered for high humidity environments, higher temperatures, and offers the highest torque capacity
- The standard curved jaw spider design has a hole in the center to accommodate small between shaft end measurements
- The 80A, 92A, and 95/98A shore spiders have a temperature capacity of 212° F
- The 64D shore spider has a temperature capacity of 230° F
- The curved jaw spider’s urethane material also resists oil, dirt, sand, grease, moisture, many solvents, as well as atmospheric effects of ozone
Misalignment Information
-
The GS Series coupling handles the following types of misalignment: axial, angular, and radial.
The coupling retains its zero backlash properties due to its spider design.
Typical Applications
-
Axial misalignment can be caused
by different shaft tolerances or
by thermal expansion of shafts.
The GS Series coupling handles
axial misalignment while keeping
reactionary forces low.
Features
-
Radial misalignment can be defined
as a measure of the offset distance
between the centerlines of the
driving and driven shafts. This type
of misalignment, due to the forces
involved, causes the highest stress.
