Atlanta B-Basic Servo Worm Gear Units



This standard range of Servo-Worm Reducers are perfect for use in applications that demand good performance, positioning and repeatability. They were specifically developed for use with state-of-the-art servo motor technology, providing tight integration of the motor to the unit. Angular backlash of less than 12 arc-minutes is provided standard.

They are available in two sizes (50 mm and 63 mm center distance) with input speeds up to 5,000 rpm, reduction ratios from 4.75 to 52:1 and output torque capacities up to 126 lb.ft. A wide range of motor couplings and mounting flanges are available for assembly to virtually all servo motors, and the hollow bore output can be used to mount output shafts, pinion shafts, or other drive elements.

Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and electronic line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.


The following are typical features of our B-Servo Gear Units:

  • Backlash: <12 arcmin
  • 2 sizes: centre distance 50 and 63mm
  • 8 ratios: 4.75; 6.75; 9.25; 14.5; 19.5; 29; 39; 50 and 52:1
  • Output torque: from 38 to 198 Nm
  • Output hollow shaft:
    • key connection
    • clamp connection

    sufficiently dimensioned and supported for high additional forces

  • Normal rigidity
  • Medium precision
  • ATEX design available







Gearing: Internal gear design was optimized to provide an angular backlash of less than 12 arc-minutes.

Bearings: Input angular contact bearings for high input speed, and ball bearings for good radial and axial load capacity.

Housing: Light weight aluminum housing for good heat dissipation, with integral input flange for servo motors and universal mounting on any face.

Output: The output bore is available with a keyway or a compression-type hub (see dimension pages). We offer a line of accessories to adapt this output to straight shafting, Rack & Pinions or other gearing types.
