Elastomeric Jaw and Wrap Couplings

Jaw and wrap couplings are material flexing couplings that transmits torque through compression of an elastomeric spider insert placed between two intermeshing jaws.

Torsionally Soft Couplings

Torsionally soft couplings use an elastomeric element to reduce harmful torque impulses. Our torsionally soft couplings increase shock absorption and damp vibration, making for lower noise levels and increased operator comfort during use. Torsional resonances are shifted to below operating speed ranges protecting the driver and driven equipment from torsional related failures.

Grid Couplings

Falk Steelflex® Grid Couplings combine the economy and high torque capacity of a gear coupling with the torsional flexibility and low maintenance of a disc or elastomeric 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.

Steelflex Coupling

Falk Steelflex Grid Couplings are available in the widest range of sizes and accommodate the highest torque load of 8,250,000 lb-in (932,250 Nm). Offering a comprehensive set of options ensures the Falk Steelflex Coupling is the right product for an assortment of our customers’ applications.

Fluid Couplings

Fluid couplings, also known as hydraulic couplings, help to prevent shock loads and allow variable speeds. By installing Falk True Torque couplings, loads can be balanced on multiple drive systems. Motors on multiple drive systems can be individually started because of the ability of one coupling to temporarily operate at 100% slip.

Falk True Torque

The True Torque system uses a mechanical release mechanism that disengages the coupling when the torque limit is exceeded, preventing damage to the equipment and minimizing downtime. The disengagement torque is adjustable and can be set to match the specific requirements of the application. The Falk True Torque coupling is a reliable and cost-effective solution for protecting valuable equipment from damage caused by torque overload.
