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.

More About Grid Couplings

What makes Steelflex different from the rest?

Proven performance equals lower cost of ownership

Five Year Heavy Duty Warranty

We’re so confident in the performance and reliability of our Falk Steelflex grid couplings that they are warranted for 5 years when lubricated with Falk Long Term Grease (LTG).

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.

Variety of Sizes and Options

Rexnord offers Falk Steelflex grid couplings in 25 sizes and 11 models, including spacer, flywheel, brake, high-speed, and controlled torque, while accommodating torque loads of 8,250,000 lb-in (932,126 Nm) and shaft diameters of 20” (508mm).
