What is a Jaw Coupling?
A jaw coupling is a type of flexible coupling commonly used in various industrial applications to connect two shafts together while accommodating misalignment, reducing vibration, and transmitting torque efficiently. It consists of two metal hubs with interlocking jaws and an elastomeric spider insert that provides flexibility and damping. This design allows for angular, parallel, and axial misalignment, making it ideal for motors, pumps, conveyors, and other machinery.
Key Features of Jaw Couplings
- High torque transmission capacity

FAQ: Common Questions About Jaw Couplings
What is the primary function of a jaw coupling?
The primary function is to connect two shafts while allowing for misalignment, damping vibrations, and transmitting torque smoothly in mechanical systems.
How do I select the right jaw coupling for my application?
Consider factors such as torque requirements, shaft sizes, misalignment types, operating speed, temperature, and environmental conditions. Refer to torque tables and consult manufacturer guidelines for accurate selection.
What types of misalignment can a jaw coupling accommodate?
It can handle angular misalignment up to 3 degrees, parallel misalignment up to 0.03 inches, and axial misalignment up to 0.02 inches, depending on the size and design.
Do jaw couplings require maintenance?
They are generally maintenance-free but should be inspected periodically for wear, especially the elastomeric spider, which may need replacement if cracked or deformed.
Can jaw couplings be used in high-temperature environments?
Yes, with appropriate spider materials like Hytrel or high-temperature elastomers, they can operate in temperatures up to 250°F or higher, but always check specifications for limits.
What are the advantages of using a jaw coupling over other types?
Advantages include easy installation, no lubrication, good misalignment capacity, vibration damping, and cost-effectiveness for many industrial applications.
How do I install a jaw coupling properly?
Ensure shafts are clean and aligned within tolerances, slide the hubs onto the shafts, insert the spider between the jaws, and tighten bolts evenly to the recommended torque without over-tightening.
What causes jaw coupling failure?
Common causes include excessive misalignment, overloading, improper installation, worn spider, corrosion, or operating beyond rated speed or temperature limits.
Are jaw couplings reversible?
Yes, they can be mounted in either direction, but ensure the spider is correctly seated and bolts are tightened uniformly for optimal performance.
Can I customize a jaw coupling for specific needs?
Many manufacturers offer customizations in bore size, material, spider hardness, and other parameters to meet unique application requirements.
