2 WRAPFLEX Now there s a simple way to increase productivity 9 sizes Torque range: 133,000 lb.in. (15 028Nm) Bore capacity: 7 1 4" (186mm) Replace in place Non-lubricated/low maintenance 3-Year Heavy-Duty Warranty Ever think that keeping your production lines running more profitably could be as simple as replacing a light bulb or opening a can with a pop-top? Quick, easy installation and replacement set new standards for reduced downtime. Because motors or drives don t need to be moved, our replace in place elements even eliminate the need for timeconsuming realignment, further reducing downtime. Available in close-coupled and spacer designs, Wrapflex couplings accommodate up to 7 1 4" (186 mm) shafts and torque loads up to 133,000 lb.in. ( Nm). For simplicity and cost-effectiveness over the life of your coupling, it just doesn t get any easier than this Wrapflex couplings from Falk. Low initial cost Advanced manufacturing methods and innovative material allow us to offer you higher capacity ratings at a more competitive price than ever before possible. Initial investment protected by the industry s first, standard 3-Year Heavy-Duty Warranty. Easy to install The compound root radius in the element teeth (patent applied for) increases flexibility for easier and quicker assembly. an be blind assembled from either direction.

3 Replace in place Design allows quick and easy element replacement. There s no need to remove hubs or realign motors or drives, reducing downtime. No maintenance needed Non-lubricated design of the tough, flexible polyurethane element reduces periodic maintenance costs. Protects equipment Patent applied for design of the flexible element minimizes effects of misalignment for improved performance and life. teeth machined with special nose radius (patent applied for) for better tooth-totooth contact. Tough, long-lasting Polyurethane element has excellent wear and chemical resistance, and a operating temperature of -40 (-40 F) to 95 (200 F). s made from carbon steel for maximum strength. Weather-resistant, high-grade nylon cover is standard. Optional carbon steel covers with black epoxy coating for highly corrosive, severe-duty applications. (Standard for sizes ) Safety first Two stainless steel button-head cap screws, positioned 180 apart, prevent relative motion between cover and element and provide a positive means of retaining the cover to the element. Flexible element is retained after failure, helping minimize the potential for damage or personal injury. Quick and easy retrofits ompact design eliminates the need for coupling guard redesign on existing applications. Stock finished bores in popular sizes and taper bores, which accept Q.D. and TaperLock bushings, are available from our worldwide distribution network for off-the-shelf availability. R31 Full-Spacer

4 WRAPFLEX Selection Guide

5 Selection Guide , June 2004 Wrapflex Quick Selection Method 1. Determine Service Factor Refer to Table 1 or 4 for motor or turbine driven applications. See Table 5 for Engine Drives. 2. Determine Equivalent Horsepower: Refer to Table 2 Under the actual hp required and opposite the service factor, read the equivalent hp. 3. Determine oupling Size: A. Refer to Table 3 Trace horizontally from the required speed to a hp value equal to or larger than the equivalent hp determined in Step 2. Read the coupling size at the top of the column. B. heck shaft diameters against coupling maximum bores shown in Table 3 and on Page 8 for the correct coupling size selected.. In Table 3, check the required speed against the allowable speed shown below the correct coupling size selected. 4. Determine oupling Dimensional Requirements: A. Determine application/design shaft spacing and check application dimension requirements against selected coupling type dimensions shown on Pages 8 thru 12. onfirm sufficient clearances for coupling. 5. onfirm that application ambient operating temperatures are between -40 (-40 F) to 95 (200 F). For applications requiring Service Factor above 1.5 and temperatures above 79 (175 F), consult Falk Engineering for selection assistance or optional high temperature elements. SERVIE FATORS are a guide, based on experience, of the ratio between coupling catalog rating and system characteristics. The system characteristics are best measured with a torque meter.
