The main advantage:

Interface: 3/8 voltage: AC220V / 200V, AC110V/run at 100V, DC24V
< > 1 29mm width of ontology, effective 30mm2 area. In diameter for 3/8,
< 2 > new shape, only lower oil seal system dynamic can slide,
< > 3 special grease, make interior without oil supply, do not affect its life,
< > 4, low power consumption, you 2W DC24V (.).
< 5 > high response, high reliability, long life, life for one time.
< > the highest use frequency for June 18 times per minute,
