Rotex Coupling: The Premium Flexible Jaw Coupling for Precision Power Transmission

The Rotex coupling stands as a benchmark in the realm of flexible jaw couplings, renowned for its reliability in damping vibration and compensating for misalignment in a wide array of machinery. At Apex Coupling, we specialize in manufacturing high-performance Rotex-type couplings that meet and exceed the standards of original designs, providing a robust and cost-effective solution for engineers worldwide. Our Rotex jaw coupling is engineered for those who demand precision, durability, and minimal maintenance in their power transmission systems.

Superior Design & Engineering for Demanding Applications

Our Rotex coupling series, compatible with industry-standard dimensions, is designed with key structural features that ensure optimal performance:

• Compact & Lightweight Design: Utilizing high-grade aluminum alloy hubs, our Rotex coupling offers an excellent strength-to-weight ratio, resulting in low inertia and high dynamic response. This makes it ideal for servo motors and other precision applications.

• Advanced Elastomer Spider: The heart of the Rotex coupling is its engineered polyurethane or NBR spider element. This component provides exceptional cushioning, vibration absorption, and wear resistance, operating efficiently in temperatures from -35°C to +80°C. The spider’s design is confined by the jaw claws to prevent deformation under centrifugal force or shock loads.

• Easy Axial Plug-in Installation: The Rotex coupling is designed for quick and tool-free assembly and disassembly. The elastomer spider can be inserted axially without moving the connected machinery, drastically reducing maintenance time and downtime.

Technical Specifications & Model Selection

Our Rotex coupling product line covers a comprehensive range to suit various torque and speed requirements. The key to selecting the correct Rotex coupling lies in matching your application’s nominal torque, shaft size, and maximum rotational speed.

We offer complete Rotex coupling sets, including the two aluminum alloy hubs and the elastomer spider. Our standard bore tolerance is H7 for a precise fit, and we support OEM, ODM, and OBM services for custom shaft diameters, keyways, set screws, or special materials.
