The RTX GR Hub is a heavy-duty, fail-safe jaw coupling hub engineered for reliable power transmission in general industrial applications. Designed to handle high torque while protecting your machinery, this standard hub series excels at absorbing shock loads and dampening operational vibrations.

Why Choose the RTX GR Standard Hub?

The RTX GR series features a specialized concave jaw geometry. This design ensures that the pressure on the elastomer insert (spider) is distributed toward the center, significantly increasing the service life of the coupling. Its “plug-in” design makes it a favorite for “blind” assemblies where space is limited and quick installation is required.

Key Benefits & Applications:

  • Fail-Safe Operation: Designed to remain operational even if the elastomer insert is damaged, preventing total system shutdown in critical moments.
  • Maintenance-Free: These hubs require no lubrication, reducing long-term overhead and downtime.
  • Versatile Compensation: Effectively manages axial, radial, and angular misalignments to protect bearings and motor shafts.
  • Industrial Strength: The go-to choice for pumps, fans, compressors, and conveyors.

Important Ordering Note:

This listing is for ONE HUB ONLY. A functioning R-TEX coupling assembly requires two hubs and one flexible insert (spider).
