LOCO and Ultra LOCO friction facings are usedin constant slip applications where a large unit is required forhigh continuous thermal dissipation. Contact your local NexenDistributor for availability.◗ HICO FRICTION FACINGS“Air Champ’s” high coefficient (HICO) friction facings areavailable for applications where higher torque is required.With HICO friction facings the unit’s static torque capacity isapproximately 40% higher than catalog rated torque.Typical uses for HICO friction facings include emergency stopsand starts.HICO friction facings are used to increase a clutch or brake’storque output when a large, standard unit will not fit a particularenvelope dimension.Contact your local Nexen Distributor for availability.1501401301201101009080706050403020INLET PRESSURE - PSIOperating PressureAIR FLOW RATE IN CFM AT 70°150 140 130 120 110 100 90 80 70 60 50 40 30 20 10 20 3/64 3/32 3/16 3/8PRESSURE IN PSIORIFICE SIZE-INCHES6543211716151413121110987654321454035302520151020Orifice size - inches5180160140120100806040

The values are based upon themaximum capability for individual misalignment.If parallel, angular and axial misalignment are all required, be certainthat the combined percentage of each does not exceed 100%. Forinstance, if 100% of the parallel misalignment rating is required, noangular or axial misalignment is allowed. If 50% of the parallel misalignmentis required, only 50% of the angular misalignment OR 50%of the axial rating will be available.Find the Product Number of the Flexible Coupling you are using inyour application and take note of the misalignment values allowed.Single Flexible CouplingsProduct Angular Axial ParallelNumber (Degrees) (In) (In)909980 1.5 0.065 0.011910080 1.5 0.070 0.012910180 1.5 0.080 0.013910280 1.5 0.090 0.014910380 1.5 0.105 0.017910480 1.5 0.120 0.019910580 1.5 0.135 0.022911780 1.5 0.155 0.026Double Flexible CouplingsProduct Angular Axial ParallelNumber (Degrees) (In) (In)909981 3.0 0.130 0.063910081 3.0 0.140 0.078910181 3.0 0.160 0.085910281 3.0 0.180 0.091910381 3.0 0.210 0.104910481 3.0 0.240 0.117910581 3.0 0.270 0.137911781 3.0 0.310 0.170D R I V E NS H A F TD R I V I N GS H A F TA N G U L A R M E A S U R E M E N T :E - A = A N G U L A R T O L E R A N C EP A R A L L E L ( M U S T B E L E S S T H A N " A N G U L A R M A X I M U M ")M E A S U R E M E N T ETo Order Coupling Type Clutch — Specify1.
