Falk

Falk Lifelign Gear Couplings’ triple-crowned teeth are crowned on the root, tip and face to articulate freely and minimize wear caused by misalignment. By eliminating tip-loading while reducing backlash and radial clearances, Lifelign’s triple-crown teeth can help protect equipment from damaging loads.

Falk Gear Coupling

The unmatched bore capacities and torque ratings of Falk Lifelign couplings often allow you to select a smaller sized coupling for a given application. In fact, selections for T frame, 60 hertz electric motors result in a drop of one coupling size for half of the 28 motor frames available. The result: quality, reliability and performance with average savings of 15-20% over competitive offerings. The smaller overall size also makes Lifelign couplings well suited for limited space applications that still require large bores and high torque loads.

Design Attributes & Advantages

• The high torque ratings and large bore capacities result in savings of up to 35% compared to the competition
• Long Term Grease (LTG) lubrication and a four-point seal provide maximum lubrication retention, extend the coupling life and contribute to reduced maintenance needs.
• 3 year heavy duty warranty when used with LTG
• Lifelign’s triple-crowned teeth are crowned on the root, tip and face to articulate freely, minimizing wear caused by misalignment. The triple- crowned teeth protects equipment from damaging loads by eliminating tip- loading while reducing backlash and radial clearances.

Falk Steel Flex Coupling

Rexnord has been manufacturing and improving our Falk Steelflex Grid Couplings for nearly a century. Known for durability in critical applications, proven performance and versatile design, these couplings are the most frequently specified grid coupling in North America.

Grid couplings are common in a variety of industries and applications because they are able to operate under extreme conditions and handle high levels of torque. There are several brands of grid couplings and they all appear to be identical. However, third party tests discussed in this paper show a wide range of results measuring the performance and durability of Falk, Dodge, and Lovejoy branded grid couplings. These results demonstrate that there can be a significant impact on the uptime and production on your system, plant or mine by the brand of grid coupling that is specified.
