SHAFT & FLUID COUPLINGS ROTATING SHAFT GUARDS
Your Complete Connection!

050101

Falks Grid, Gear, Disc and Elastomer Couplings Have One Thing In Common. They Do The Job, No Matter What The Job Is.
The difference is often in the details. The difference between failure and long life, between smooth operation and downtime, between making or losing money on the factory floor. Falk understands that different couplings suit different applications. So weve designed and manufactured a variety of state-of-the-art couplings to meet virtually any requirement. Whether you need more flexibility, lower maintenance, high torque load protection, simple cost-effective performance or something else, we can specify a coupling to suit you. Falk Speed Quote software or a team of qualified power transmission specialists can analyze your application, and determine how special characteristics including bore fit options, stiffness, balance, shaft gaps, operating speed and environmental conditions can affect coupling selection.

Falk couplings are available in standard or dual purpose designs, with special configurations for unique requirements. And each Falk coupling type is offered in sizes and with torque and bore capacities to fill a whole host of application parameters. At Falk, we know couplings. How important they are. How reliable they need to be. And how the right coupling is one sizable detail that can make the critical difference in your operation.
Complete Drive Systems from Falk
Used in a broad range of applications, Falk Fixed-Fill Fluid Couplings provide consistently longer, smoother, time-controlled starts with lower starting torques and softer torque transfer. Ideal for conveyors using multiple drives, Falk Fluid Couplings allow for staggered motor starting and load sharing.
But Falks capability isnt limited to just selling a component, we sell drive systems incorporating the gear drives, couplings, backstops, brakes, guards & motors, all mounted on a bedplate, swing base or alignment free assembly. Plus, our ready availability keeps you producing even in the most remote places on Earth.

Wrapflex is a low cost, low maintenance, non- lubricated elastomer coupling from Falk. Quick, easy installation and replacement sets new standards for reduced downtime. Because motors dont need to be moved, our replace- in- place elements even eliminate the need for time consuming realignment. Falk Wrapflex Elastomer Couplings are backed by a 3- year warranty. Wrapflex is a great low cost, general purpose pump coupling!
The easily replaceable grid in a Falk Steelflex Grid Coupling combines the high- load capabilities of a gear coupling with the flexibility of an elastomer design. Backed by a 5- year warranty, Falk Steelflex couplings require no periodic maintenance when lubricated with Falk supplied LTG (Long Term Grease) at installation. Steelflex is the ideal coupling for gear driven, positive displacement, and high capacity pumps!
Close tolerances and registered fits allow Falk Freedom Disc Couplings to provide continuous highspeed service with virtually no maintenance. Falks one- piece discpacks assure simple maintenance and a no backlash connection. Falk Disc Couplings are backed by a 3- year warranty and provide a practical alternative to lubricated and elastomer couplings for many applications. Freedom is the answer for pumps; where high reliability is demanded!
Triple- crowned for maximum capacity, Falk Lifelign Gear Couplings have bigger bores and higher ratings providing lower cost selections. When used with Falk LTG (Long Term Grease) Falk Gear Couplings are backed by a 3- year warranty. Lifelign couplings make a great choice for axial impeller adjustment and high torque requirements!

Just Trim & Fit - Orange Peels patented trim-and-fit design revolutionizes equipment guard convenience and value, so you can get the job-site safety you want without the expense and long lead times of custom engineered guards. Rotating Shaft Guards Because Orange Peel guards are sized to your overall application, they can be installed in 3 easy steps: make 3 simple measurements; using dimensioned trim lines; make 3 quick trim cuts, then simply fit the hardware. In less than an hour, Orange Peel can have you up and running. Optional ANSI and ISO safety labels are also available.
