STEELFLEX® Redefining total coupling value

Features that give Steelflex the lowest lifetime operating cost

Longer Life

Tapered grids, made of high strength alloy steel, are quenched and tempered to spring hardness. The grid surface is then precision shot peened to compress the surface molecules.

The effect is a dramatic increase in rating, providing reserve strength for longer life or allowing a smaller size coupling to be selected. This precision technology was originally used in the production of sophisticated aircraft components.

Extended Maintenance Periods

Now you can install Steelflex and lubricate it with Falk Long Term Grease (LTG) and forget periodic, routine maintenance for fiveyears. Falk LTGgrease was developed specifically for couplings.It resists the separation of the oil and thickening agent that occurs in typical greases. The initial use of Falk LTGcoupling grease will eliminate routine lubrication cycles while still providing the necessary lubrication to the tapered grid. With LTG, Steellflex combines the high torque performance of a gear coupling and the low maintenance of a disc or elastomer coupling.

FALK STEELFLEX The simplest, most cost-effective coupling

Falk originated the tapered grid design as well as shot peening to increase fatique strength and torque ratings. Falk Steelflex redefines total coupling value up to 7.5 million in-lb, 932 0 Nm torque. Steelflex offers simpler initial installation than gear couplings. The unique “replace in place” design eliminates the need to move hubs or re-align shafts, reducing element change-out time. When you look at the overall savings in initial costs, spare parts costs, and labor costs for installation, alignment and replacement - plus improved ratings and a 5 Year Heavy-Duty Warranty - it’s easy to see what Falk’s Steelflex Grid Couplings have over the competition. No other coupling in the torque range can touch Steelflex for cost-effective performance and reliability.

Quick, Easy Installation… Replace-In-Place Design

The grid is the wearing member of a Steelflex coupling and it is a fraction of the complete coupling cost. Tapered grids are accessible through the quickly removable cover. The replace-in-place design of the replacement grids allows them to be dropped in without the need to remove or reposition hubs or realign shafts as required with gear couplings and many elastomer designs. When coupling-connected equipment must be moved, the job takes longer and costs a lot more.

Equipment Protection Against Shaft Misalignment

The grid is free to rock, pivot and float within the hub teeth. Generous misalignment capacity is provided without producing detrimental bearing side loads created by other couplings.

Equipment Protection Against Shock/ Vibratory Loads

Torsional flexibility is the ability of Falk Steelflex couplings to torsionally deflect when subjected to normal shock or vibratory loads, providing flexible accommodation to changing load conditions. Consequently,Steelflex tunes the drive system. It absorbs impact energy by spreading it over an

Versatile Designs

Two cover designs are available in the popular sizes. Standard spacer, piloted, high speed, brakewheel or disc, and controlled torque designs are also available.

Worldwide Availability

Steelflex couplings and component parts, are available in popular sizes andtypes, inboth inch or metric. Our distribution centers and worldwide distribution network offer the largeststock of rough bore, finish straight bore and Taper-lock bushed hubs of any shaft coupling on the market. Plus, Steelflex grid couplings are warranted for 5 Years when lubricated with Falk LTG Long Term Grease.

increment of time. It damps vibration and reduces peak or shock loads by as much as 30%. It is a true shock absorber for rotary motion, relying on the predictable resilience of the steel grid for torsional flexibility.

Warranty extends for 3 years from date of shipment. Does not apply to Falk Omnibox, Ultramite, Fluid Couplings, Renew and spare parts. Warranty applies to Steelflex and Lifelign couplings with the use of Falk Long Term grease.

Falk Factory Warranty We’re so confident in the performance and reliability of our latest generation of Falk heavy-duty products that we’re backing this comprehensive offering with the best standard warranty in the business. Our full, 3-year Heavy-Duty Warranty provides “shaft-to-shaft” protection on all Falk components – including bearings and seals. It’s an industry first... and one more powerful reason why Falk is your ultimate bottom-line drive and coupling value. Steelflex grid couplings are warranted for 5 Years when lubricated with Falk LTG Long Term Grease.

General Information – Falk standards apply unless otherwise specified.

– All Dimensions are for reference only and are subject to change without notice unless certified.

– Unless otherwise specified, Falk coupling hubs will be bored for CLEARANCE FIT with a setscrew OVER the keyway or INTERFERENCE FIT without a setscrew.

– Torque ratings of couplings utilizing Taper-Lock bushings can differ from those that do not. Refer to Falk for details.

– If Falk is to supply coupling hubs bored for Taper-Lock bushings, the bushing manufacturer MUST be noted on the order.

– Consult Falk when limited end float is required.

Reference Notes

† Peak torque capacity is two times the published rating. ‡ Consult Factory for higher speeds.

Maximum bores are reduced for hubs furnished with an INTERFERENCE FIT and a setscrew OVER the keyway. Refer to Falk for details. Recommended key sizes for the listed maximum bores are shown in Table 1 on Page 3.

Minimum bore is the smallest bore to which a RSB hub (rough stock bore) hub can be bored. Depending upon coupling size, rough stock bore hubs may have only a blind centering hole or a through hole that will permit remachining of the hubs to the minimum bores specified.
