SWQ Series Jaw Coupling

Product Overview

The SWQ Series Jaw Coupling (Quick Change Type) is a high-efficiency flexible coupling designed for rapid maintenance and minimal downtime in demanding industrial applications. It features an advanced quick-change elastomeric element design, allowing fast replacement without disturbing the hubs or connected equipment.

Built on the proven jaw coupling principle, the SWQ Series combines reliable torque transmission, excellent vibration damping, and superior ease of maintenance, making it ideal for continuous process industries and critical machinery.

Key Features & Benefits

Optimized Hub Design

Specially engineered hub configuration ensures secure shaft mounting with improved ease of installation and removal.
No Metal-to-Metal Contact

The elastomeric spider prevents direct hub contact, reducing wear, noise, and extending operational life.
High Misalignment Capability

Accommodates angular and parallel misalignment, minimizing stress on connected equipment.
Maintenance-Free Operation

No lubrication required, ensuring cost-effective and hassle-free performance.
Excellent Shock & Vibration Damping

Reduces torsional vibrations and absorbs impact loads, protecting machinery.
Easy Assembly & Replacement

Simplified design allows quick installation and easy spider replacement, reducing downtime.

Construction & Working Principle

Components:
Two Metallic Hubs
Manufactured from high-quality cast iron or steel for durability and long service life.

Quick Change Elastomeric Element
Specially designed for easy insertion and removal, available in:
• NBR (Buna-N) – General-purpose applications
• Polyurethane – Higher torque capacity and wear resistance
• Hytrel® – High temperature and high torque performance

Retention Mechanism (if applicable)
Ensures secure positioning of the element during operation.

Working Principle:
Torque is transmitted through the compression of the elastomeric element between the coupling jaws. The quick-change design allows the element to be replaced rapidly without axial hub movement, ensuring continuous and efficient operation.

Advantages Over Standard Jaw Couplings
• Faster element replacement compared to conventional designs
• No need to move hubs or shafts during maintenance
• Reduced maintenance time and labor cost
• Ideal for continuous and high-uptime operations
• Improved operational efficiency
