| Features | Models & Symbols | Specification | Product drawing | The FR series component type is a flat, thin type for high torque. It consists of four parts like the FB series and operates using the same principle as the cup type. It is basically structured in the same way as the FB series and supports high torque capacity by arranging the wave generator bearings in two lines and widening the tooth width of the circular spline and the flexspline. • Flat shape type • High torque capacity • Compact and simple design • High positioning and rotational accuracies • Coaxial input and output Type: FR series Size: 14, 20, 25, 32, 40, 50, 65, 80, 100 Reduction ratio:  50, 78, 80, 88, 96, 100, 104, 110, 120, 128, 131, 132, 157, 158, 160, 194, 200, 208, 242, 258, 260, 320 Models and symbols: 2= Component type Specification: GR= new type Size Reduction ratio Rated torque at 2000r/min Allowable peak torque at start and stop Allowable average torque Allowable maximum momentary torque Maximum input speed (Grease lubrication) N·m N·m N·m N·m r/min 14 50 4.4 5.4 5.4 13.7 3600 88 5.9 9.8 9.8 19.6 100 7.8 13.7 9.8 19.6 110 7.8 13.7 9.8 19.6 20 50 25 34 34 69 3600 80 34 41 41 72 100 40 53 49 94 128 40 67 49 102 160 40 77 49 86 25 50 39 55 55 108 3600 80 56 69 69 122 100 67 91 91 160 120 67 108 108 190 160 67 135 108 172 200 67 147 108 172 32 50 76 108 108 216 3600 78 108 137 137 245 100 137 176 176 323 131 137 255 216 451 157 137 294 216 500 200 137 314 216 372 260 137 314 216 372 Size Reduction ratio Rated torque at 2000r/min Allowable peak torque at start and stop Allowable average torque Allowable maximum momentary torque Maximum input speed (Grease lubrication) N·m N·m N·m N·m r/min 40 50 137 196 196 353 3300 80 196 245 245 431 100 255 314 314 549 128 294 392 392 686 160 294 461 451 813 200 294 529 451 745 258 294 627 451 745 50 80 363 441 441 784 3000 100 470 578 578 1019 120 559 696 696 1225 160 559 833 833 1470 200 559 960 843 1411 242 559 1176 843 1411 65 78 745 921 921 1617 2200 104 1070 1340 1340 2360 132 1070 1650 1570 2890 158 1070 1970 1570 3450 208 1070 2180 1570 2590 260 1070 2200 1570 2590 80 80 1320 1640 1640 2870 2000 96 1660 2050 2050 3590 128 2300 2820 2830 4960 160 2350 3380 3130 5940 194 2350 4300 3130 6900 258 2350 4350 3130 5170 320 2350 4350 3130 5170 100 80 2330 2870 2870 5040 1700 100 3200 3940 3940 6920 120 3890 4780 4780 8400 160 4470 6230 5720 10950 200 4470 7090 5720 12440 242 4470 7960 5720 9410 320 4470 7960 5720 9410 (Unit:mm) Symbol /Size 14 20 25 32 40 50 øA (h6) 50 70 85 110 135 170 B 8.5 12 14 18 21 26 C 1 1 1 1 1 1 D 18 25 29 37 43 53 Weight(kgf) 0.2 0.5 0.8 1.7 3.0 6.0 Symbol /Size 65 80 100 - - - øA (h6) 215 265 330 - - - B 35 41 50 - - - C 1 1 1 - - - D 71 83 101 - - - Weight(kgf) 12.0 22.3 42.6 - - - Please confirm dimensions and specification with the drawing issued by Harmonic Drive Systems. | Features | Models & Symbols | Specification | Product drawing |
