1. Jaw & Spider
Couplings
A BRIEF OVERVIEW BY JOSEPH BARLOW

3. Jaw & Spider couplings are popular because
they are versatile and robust.

4. Jaw & Spider Couplings are Failsafe
Wide Temperature Range
Can handle Angular Misalignment
Good Torque, Speed, Chemical Resistance, & Dampening characteristics

5. Versatility
&
Robustness
 Dampening reduces effect of shock and vibration.
 Angular Misalignment (slight)

6. Able to endure tough
Environments

7. Jaw & Spider Couplings
are forgiving
but
Alignment is still Critical

8. Torsional Misalignment

9. Overload Disadvantages
Sheared
Spider
Overloaded
Hub Hub overload

10. Bottom Line
Low Cost
Availability
Servicability
