In order to ensure that the spindle motor can work normally, the disassembly and assembly must be made by experienced professional operators, in a clean environment, as well as the use of appropriate tools, avoid indiscriminate beat. Of temporarily without electric spindle to use compressed air will do more than Shuichui water cavity, the sleeve and the shaft head and a shaft hole to oil anti rust and placed in a cool, dry place.JGD Motorized Spindle with Constant TorqueModelMax Revolving speed(r/min)Motor ParametersOverall DimensionChuck ModelCooling ModeWeight(KG)Power(kW)Voltage(V)Frequency(HZ)Current(A)DD1LL1L2JGD-40/0.07400000.0748300~6661.24040131520ER8Self-cooling1.1JGD-48/0.09500000.0952300~8331.24840132520ER8Self-cooling1.3JGD-48/0.15600000.2575400~7001.24840112520ER8Water-cooling1.3JGD-48/0.25600000.2575400~10002.04840112520ER8Water-cooling1.3JGD-48/0.3500000.375400~8332.54842122520ER8Water-cooling1.4JGD-58/0.3500000.3110300~8331.65846146520ER11Self-cooling2.7JGD-58/0.4240000.4110300~4002.25846166520ER11Self-cooling3.0JGD-62/0.75400000.75220400~6662.06246170520ER11Water-cooling3.3JGD-62/0.8300000.8220400~5002.26250188823ER11Water-cooling3.5JGD-62/1.0R60600001.022010002.862501781020ER11Water-cooling3.6JGD-72/1.5400001.52206664.27252196823ER11Water-cooling4.5JGD-80/0.75240000.751504003.08060200624ER16Self-cooling7.1JGD-80/1.5300001.5220400~5004.28060200624ER16Water-cooling7.0JGD-80/1.5R30240001.52204004.280602101524ER16Water-cooling7.0JGD-80/1.5R40400001.52206664.28060180824ER16Water-cooling5.5JGD-80/1.5R60600001.522010004.28060180624SK06Water-cooling5.5JGD-80/2.2240002.2220400680762401629ER20Water-cooling8.5JGD-85/1.5240001.52204004.28576214726ER16Water-cooling7.5JGD-85/2.2240002.2220400685762401629ER20Water-cooling9.0JGD-105/2.2240002.2220350~4006105782621529ER20Water-cooling13.5JGD-105/3.2240003.2380300~4005105782821530ER20Water-cooling16.5JGD-125/4.2240004.2380300~4007.5125942914332ER25Water-cooling22JGD-125/5.5210005.5380300~35011125963045232ER32Water-cooling25JGD-40-0.07JGD-48-0.3JGD-48-0.09 JGD-48-0.15JGD-48-0.25JGD-58-0.3 JGD-58-0.4 JGD-62-0.8JGD-62-0.75JGD-62-1.0R60JGD-72-1.5 JGD-80-0.75 JGD-80-1.5 JGD-80-1.5R30JGD-80-1.5R40JGD-80-1.5R60JGD-80-2.2 JGD-85-1.5 JGD-85-2.2 JGD-105-2.2 JGD-105-3.2JGD-125-4.2JGD-125-5.5
