The Lovejoy 1000 Series Grid Coupling Fully Interchangeable with the industry standard With readily available full assemblies and Benefits of Lovejoy Grid Couplings: interchangeable components, Lovejoy's new ✔ Interchangeable with industry standard hubs and grid springs – all the way up to size 1200! line of grid couplings gives you the ability to avoid lengthy shutdowns. Our grid couplings ✔ Clearance fit hubs available in sizes combine high-torque, high-horsepower operation with vibration, shock and misalignment 1020-1090 have two set screws standard ✔ The tooth profile of the grid hub is shot blasted for added strength and longer life capabilities not provided by other metallic coupling types. Ten standard model sizes feature ✔ Puller holes are standard for interference fit hubs, sizes 1100 through 1200 an advanced design with high-tensile alloy grids that reduce vibration by as much as 30 percent. Our larger grid couplings meet the demands of tough applications like crushers, conveyors, and pulverizers commonly found in aggregate ✔ Cover fasteners are available in either metric or imperial sizes ✔ Grease packets are included with cover sets through size 1090 ✔ Standard hubs accommodating industries. Taper-Lock bushings are standard ® Interchange Chart Horizontal — Split Cover Lovejoy® Falk® Morse/Browning® Dodge® Kop-Flex® Size Steelflex® Grid-Flex® Grid-Lign® Kop-Grid® 1020 1020T10 GF2020H 1020T10 1020H 1030 1030T10 GF2030H 1030T10 1030H 1040 1040T10 GF2040H 1040T10 1040H 1050 1050T10 GF2050H 1050T10 1050H 1060 1060T10 GF2060H 1060T10 1060H 1070 1070T10 GF2070H 1070T10 1070H 1080 1080T10 GF2080H 1080T10 1080H 1090 1090T10 GF2090H 1090T10 1090H 1100 1100T10 GF2100H 1100T10 1100H 1110 1110T10 GF2110H 1110T10 1110H 1120 1120T10 GF2120H 1120T10 1120H 1130 1130T10 GF2130H 1130T10 1130H 1140 1140T10 GF2140H 1140T10 1140H 1150 1150T10 1160 1160T10 1170 1170T10 1180 1180T10 1190 1190T10 1200 1200T10 Vertical — Split Cover Falk® Morse/Browning® Dodge® Kop-Flex® Steelflex® Grid-Flex® Grid-Lign® Kop-Grid® 1020T20 GF2020V 1020T20 1020V 1030T20 GF2030V 1030T20 1030V 1040T20 GF2040V 1040T20 1040V 1050T20 GF2050V 1050T20 1050V 1060T20 GF2060V 1060T20 1060V 1070T20 GF2070V 1070T20 1070V 1080T20 GF2080V 1080T20 1080V 1090T20 GF2090V 1090T20 1090V 1100T20 GF2100V 1100T20 1100V 1110T20 GF2110V 1110T20 1110V 1120T20 GF2120V 1120T20 1120V 1130T20 GF2130V 1130T20 1130V 1140T20 GF2140V 1140T20 1140V Larger Sizes Give You Greater Options Vertical Style Horizontal Style Horizontal Style 1000 Series Grid Couplings Maximum Torque Size in-lbs Min Max OD OAL G Length Thru Bore LTB HD L SL T 1020 422 0.500 1.125 4.00 3.88 0.13 1.88 1.56 2.63 0.50 #8-32 4.2 1030 1,200 0.500 1.375 4.38 3.88 0.13 1.88 1.94 2.69 0.31 #8-32 5.7 7.610 1040 2,000 0.500 1.625 4.63 4.13 0.13 2.00 2.25 2.75 0.44 #10-24 7.4 11.190 1050 3,500 0.500 1.875 5.44 4.88 0.13 2.38 2.63 3.13 0.62 #10-24 12.0 24.850 1060 5,500 0.750 2.125 5.94 5.13 0.13 2.50 3.00 3.63 0.44 #10-24 16.0 40.660 1070 8,000 0.750 2.500 6.38 6.13 0.13 3.00 3.44 3.75 0.88 1/4-20 23.0 63.180 1080 16,500 1.000 3.000 7.63 7.13 0.13 3.50 4.13 4.56 0.94 1/4-20 39.0 154.000 1090 30,000 1.000 3.500 8.38 7.88 0.13 3.88 4.88 4.81 1.03 5/16-18 1100 50,500 1.625 4.000 9.88 9.69 0.19 4.75 5.59 6.13 Bore Outer Dia Overall Length Gap Hub Dia Length Set Screw Location Size Weight lbs Solid Moment of Inertia WR2 lb-in2 Solid 4.830 56.0 269.000 93.0 609.000 1110 75,000 1.625 4.500 10.63 10.19 0.19 5.00 6.31 6.36 120.0 923.000 1120 110,000 2.375 5.000 12.13 12.00 0.25 5.88 7.06 7.55 179.0 1,755.000 1130 160,000 2.625 6.000 13.63 13.00 0.25 6.38 8.56 7.69 266.0 3,375.000 1140 230,000 2.625 7.000 15.13 14.75 0.25 7.25 10.00 7.92 392.0 6,306.000 1150 320,000 3.000 8.000 17.84 14.64 0.25 7.20 10.60 8.42 523.0 1160 457,000 4.188 9.000 19.74 15.83 0.25 7.80 12.00 10.43 720.0 1170 600,000 4.188 10.000 22.30 17.24 0.25 8.50 14.00 11.85 1,022.5 1180 830,000 5.125 11.000 24.80 19.04 0.25 9.40 15.50 12.24 1,341.7 1190 1,100,000 6.000 12.000 26.60 20.64 0.25 10.20 17.20 12.80 1,710.0 1200 1,500,000 6.000 13.000 29.80 22.24 0.25 11.00 19.60 14.00 2,331.0 Notes: 1.

Angular Under angular misalignment, the grid-groove design permits a rocking and sliding action of the grid and hubs without any loss of power through the resilient grid. End float is permitted for both driving and driven members because the grid slides freely in the grooves.
