Rotex 19 Coupling: The Versatile, High-Performance Flexible Jaw Coupling for Industrial Drives

In the realm of power transmission, few components offer the perfect balance of simplicity, reliability, and performance quite like the Rotex 19 coupling. This precision-engineered flexible jaw coupling has become an industry standard for connecting motors to driven equipment across countless applications. The GE 19 type Rotex coupling from Apex Coupling represents the pinnacle of this trusted design, manufactured with precision components to deliver zero-backlash torque transmission, exceptional vibration damping, and maintenance-free operation. When your machinery demands a dependable, cost-effective flexible connection, the Rotex 19 coupling is the proven choice.

Engineered for Superior Performance and Durability

The Rotex 19 coupling features a robust design that combines high-strength materials with precision engineering. The coupling hubs are manufactured from 45# steel with a durable blackening surface treatment, providing excellent corrosion resistance and a professional black finish. This material choice ensures the Rotex 19 coupling can withstand demanding industrial environments while maintaining its structural integrity over millions of operating cycles.

The heart of this high-performance flexible coupling is its advanced elastomeric spider, also known as the flexible element. This component is precision-molded from high-quality engineering plastic, engineered to provide:

• Excellent cushioning and vibration reduction to protect connected equipment from damaging torsional vibrations

• Superior wear resistance for extended service life in continuous operation

• Wide temperature range capability from -35°C to +80°C, ensuring reliable performance in diverse environments

The Rotex 19 coupling’s spider operates maintenance-free, eliminating the need for lubrication and reducing ongoing maintenance costs.

Advanced Design Features for Optimal Performance

What sets this Rotex 19 coupling apart is its sophisticated elastomer design. The spider is limited by convex claw blocks, which serve two critical functions:

1. Preventing internal deformation caused by impact loads during operation

2. Eliminating external deformation from centrifugal forces at high rotational speeds

The large concave surface of the convex claw ensures that surface pressure on the involute tooth profile remains minimal. This innovative design means that even under overload conditions, the teeth will not wear or deform, ensuring long-term reliability and consistent performance. The spider hardness is rated at 98 Shore A, providing the optimal balance of flexibility and load capacity for nominal torque transmission.

Easy Installation and Maintenance

The Rotex 19 coupling features an axial plug-in installation design that simplifies assembly and reduces downtime. The spider can be easily inspected or replaced without disturbing the hub alignment or moving connected equipment. This user-friendly feature is invaluable in applications requiring regular maintenance or in tight installation spaces.
