The compact design and hub style output of the new PGD series of inline precision servo gearboxes is ideal for equipment requiring high-speed, high-precision indexing movement. Available in six gear ratios ranging from 5:1 to 50:1, the hub style gearboxes feature a backlash rating of less than 3 arc-minutes and exceptional torque handling capabilities. High torsion stiffness and low backlash of the planetary gearing combine to provide outstanding positioning accuracy. Additional features include helical-cut planetary gears for quiet operation and reduced vibration as well as uncaged needle roller bearings for high rigidity and torque. Maintenance free, the gearboxes contain high-viscosity, anti-separation grease which does not migrate away from the gears. Starting at $722.00, SureGear PGD-series gearboxes have an IP55 rating and a five-year warranty.
