GFX 48-55 Guardian Coupler Kit | 1-3/8″ Hub

The GFX 48-55 OEM Drive Coupler is a Guardian-series flexible coupling element for industrial power transmission. This variant of the Guardian coupling line provides torsional vibration damping for compressor packages, pump drives, and engine-driven industrial equipment.

Guardian couplings are found across a range of industrial applications where reliable torque transfer and vibration isolation are needed between the driver and driven components. The GFX 48-55 element is sized for medium-duty installations and drops into Guardian hub assemblies that match this coupling size. The elastomeric element absorbs torsional oscillation from diesel engines and electric motors while compensating for minor shaft misalignment, extending the service life of bearings and seals on connected equipment.

During element replacement, separate the hubs, remove all old material, and inspect hub contact surfaces for wear. Install the new GFX 48-55 element with proper engagement confirmed and verify shaft alignment before returning to loaded operation.
