| Features | Models & Symbols | Specification | Product drawing | The FB series component type has pursued flatness and thinness. It consists of four parts and operates using tha same principle as the cup type of the CSG/CSF series. The flexspline of the pancake type is shaped like the flexspline of the cup type with a cut bottom and is structured to have an additional circular spline with the same number of teeth as the flexspline. • Flat shape type • Compact and simple design • High positioning and rotational accuracies • Coaxial input and output Type: FB series Size: 14, 20, 25, 32, 40, 50 Reduction ratio: 50, 78, 80, 88, 100, 110, 120, 128, 131, 157, 160 Models and symbols: 2=Component type Specification: G= 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 2.6 3.2 3.2 6.9 3600 88 4.9 7.8 7.8 15.7 100 5.9 9.8 9.8 15.7 110 5.9 9.8 9.8 15.7 20 50 14 18 18 34 3600 80 17 21 21 35 100 22 26 25 47 128 24 33 25 58 160 24 38 25 59 25 50 23 30 30 54 3600 80 31 39 39 70 100 39 52 52 91 120 39 61 61 94 160 39 76 61 86 32 50 44 60 60 108 3600 78 63 75 75 127 100 82 98 98 176 131 82 137 118 235 157 82 157 118 235 40 50 88 118 118 216 3300 80 118 147 147 265 100 157 186 186 343 128 167 235 235 372 160 167 284 274 353 50 80 216 265 265 480 3000 100 284 253 253 627 120 304 421 421 706 160 304 510 490 666 (Unit:mm) Symbol /Size 14 20 25 32 40 50 øA (g7) 50 70 85 110 135 170 B 5 6 8 10 13 16 C 0.5 0.5 0.5 0.5 1.0 1.0 D 10.5 12.5 16.5 20.5 27 33 Weight(kgf) 0.1 0.3 0.5 1.0 1.8 2.9 Please confirm dimensions and specification with the drawing issued by Harmonic Drive Systems. | Features | Models & Symbols | Specification | Product drawing |
