High-strength alloy steel grids are tempered to spring hardness and precision shot peened for increased fatigue strength, providing reserve strength for longer life or allowing a smaller size coupling to be selected.
No need to re-lubricate for 5 years when using Falk Long Term Grease (LTG).
Tapered T-Grid profile fits smoothly into hub for easy installation and maintenance.
Durable nitrile seals prevent lubricant leaks and entrance of water, dust, or other particles.
Operating speeds up to 10,000 RPM, even in high shock and vibratory conditions.
Replace-in-place design eliminates the need to move hubs or re-align shafts, reducing element change out time.
Up to 20” (508mm) bore capacity.

Outperforms the Competition

Third party testing has shown that Falk Steelflex couplings are 4.7X and 16X more durable than the top two competitors, and capable of surviving up to 2X longer in real-life misalignment conditions.

Combines the Best Features of Alternative Couplings

Falk Steelflex grid couplings general purpose design combines the economy and high torque capacity of a gear coupling with the torsional flexibility and low maintenance of a disk or elastomeric coupling.
