| Features | Models & Symbols | Specification | Product drawing | SHG series unit type Harmonic Drive®, which are improved versions of the SHF series, are for high-torque operation. Based on the development concepts of upgrading the load capacity, strength reliability and extending the service life, SHG series unit type Harmonic Drive® have been improved in respect to the following performance capabilities as compared to SHF series products of the same size: • Rated torque improved 30% • Allowable peak torque at start-up/stoppage improved 30% • Allowable maximum momentary torque improved 30% • Ratcheting torque improved 30% • Rated service life extended 42% (to 10,000 hours) • In respect to external dimensions, rigidity, angle transmission accuracy, input moment of inertia, etc., SHG series unit type products are the same as SHF series products. Type: SHG series Size: 14, 17, 20, 25, 32, 40, 45, 50, 58, 65 Reduction ratio: 50, 80, 100, 120, 160 Models and symbols: • 2A-GR = Component type ("2A-R" for sizes 14 and 17) • 2UH = Unit / Hollow shaft type • 2UJ = Unit / Shaft input type • 2SO = Simple unit (Flat type) • 2SH = Simple unit (hollow shaft type) Special specification (Suffix "SP" is only special specification) 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 7.0 23 9 46 8500 80 10 30 14 61 100 10 36 14 70 17 50 21 44 34 91 7300 80 29 56 35 113 100 31 70 51 143 120 31 70 51 112 20 50 33 73 44 127 6500 80 44 96 61 165 100 52 107 64 191 120 52 113 64 191 160 52 120 64 191 25 50 51 127 72 242 5600 80 82 178 113 332 100 87 204 140 369 120 87 217 140 395 160 87 229 140 408 32 50 99 281 140 497 4800 80 153 395 217 738 100 178 433 281 841 120 178 459 281 892 160 178 484 281 892 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 50 178 523 255 892 4000 80 268 675 369 1270 100 345 738 484 1400 120 382 802 586 1530 160 382 841 586 1530 45 50 229 650 345 1235 3800 80 407 918 507 1651 100 459 982 650 2041 120 523 1070 806 2288 160 523 1147 819 2483 50 80 484 1223 675 2418 3500 100 611 1274 866 2678 120 688 1404 1057 2678 160 688 1534 1096 3185 58 80 714 1924 1001 3185 3000 100 905 2067 1378 4134 120 969 2236 1547 4329 160 969 2392 1573 4459 65 80 969 2743 1352 4836 2800 100 1236 2990 1976 6175 120 1236 3263 2041 6175 160 1236 3419 2041 6175 • Hollow shaft type unit (Full unit <2UH> / simple unit <2SH>) indicates the construction of the simple unit type.
