What Is a GS Spider Coupling? Complete Guide to GS Flexible Jaw Couplings
A GS spider coupling is a flexible jaw coupling designed to connect two rotating shafts while transmitting torque and reducing vibration and shock.
The coupling normally consists of three main components:
Two Metal Hubs + One Flexible Spider Insert
The spider is positioned between the curved jaws of the two hubs.
How Does a GS Spider Coupling Work?
When the driving shaft rotates, the first coupling hub transfers torque to the elastomeric spider.
The spider then transfers the torque to the second hub and driven shaft.
At the same time, the flexible spider helps:
- Absorb vibration
- Reduce torsional shock
- Compensate for limited misalignment
- Protect connected machinery
- Reduce maintenance requirements
What Is the GS Spider Insert Made From?
GS spider inserts can be manufactured from different elastomer materials depending on the application.
Common materials include:
- PU
- NBR
- Hytrel
- Other engineering elastomers
For demanding applications involving heat, oil and wear, Hytrel GS spider inserts can be considered.
GS Spider Coupling Sizes
Typical GS spider sizes include:
GS-7, GS-10, GS-14, GS-19, GS-24, GS-28, GS-38, GS-42, GS-48, GS-55, GS-65, GS-75 and GS-90.
The correct model should be selected according to the coupling dimensions, shaft size, torque, speed and application.
Where Are GS Spider Couplings Used?
GS flexible jaw couplings are suitable for many industrial machines, including:
- Motors
- Pumps
- Gearboxes
- Compressors
- Fans
- Conveyors
- Machine tools
- Automation equipment
- Manufacturing machinery
How Do I Choose a GS Spider Coupling?
Before ordering, check:
- Coupling model
- Outside diameter
- Hub dimensions
- Shaft diameter
- Operating speed
- Torque
- Operating temperature
- Oil or chemical exposure
- Required spider material
If you are unsure about the model, send the existing coupling dimensions or a photo to the manufacturer.
