Flexible Jaw Couplings
ISL Products International offers a premium selection of flexible jaw couplings designed to seamlessly connect continuous-duty electric motors with driven machinery, pumps, and gearboxes. Engineered to accommodate slight angular (up to 1°) and parallel (up to 0.015 in) shaft misalignments, these couplings are an ideal choice for applications demanding both precision and reliability.
Key Features & Benefits:
- Optimized Torque Transmission: Utilizing compression-type elastomeric elements, our flexible jaw couplings deliver higher load capacity and superior torque transmission compared to shear-type designs.
- Enhanced Torsional Stiffness: With reduced twist between hubs, these couplings minimize backlash, ensuring near-synchronous movement between the driving and driven shafts—perfect for precise operations in conveyors, pumps, and similar applications.
- Fail-Safe Operation: In the event of an elastomeric spider failure, the coupling continues to function by allowing the driving jaws to contact the driven jaws directly. This fail-safe design helps prevent unexpected downtime, giving maintenance teams the flexibility to schedule repairs conveniently.
- Easy Installation & Inspection: Featuring a simple three-piece assembly—metal hubs with an interposed, contoured elastomeric spider—our flexible jaw couplings are straightforward to install, even in confined spaces.
Discover the perfect balance of performance, safety, and ease-of-use with our flexible jaw couplings. Browse our selection of flexible jaw couplings or contact our experts for guidance in choosing the ideal coupling for your application.
