AutomationDirect Hub-style servo gearboxes
SureGear precision servo gearboxes now include hub-style inline models. The PGD’s compact design and hub-style output make the line suitable for equipment that requires high-speed, high-precision indexing movement. Torsion stiffness and the low backlash of the planetary gearing combine help to provide positioning accuracy. The gearboxes feature a backlash rating of less than 3 arc-minutes, are available in gear ratios ranging from 5:1 to 50:1 and contain high-viscosity, anti-separation grease that does not migrate away from the gears and does not leak through the seal. Additional features include helical-cut planetary gears for quiet operation and reduced vibration.
