They are available in four sizes (50 mm to 100 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 885 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, zero-backlash axis drives and electronic line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
These reducers are typically selected based on the peak cycle forces, which usually happen during accelerations and decelerations. These cycle forces depend on the driven load, the speed vs. time profile for the cycle, and any other external forces acting on the axis. For more selection information, please follow this PDF link.

information will be reviewed by our engineers, who will recommend the best
solution for your application.
The following table gives the output torque ratings (in lb.ft.) for the High-Torque (HT) Servo-Worm Reducers at various input speeds and ratios. Service factors need to be applied to these ratings to make a proper selection.
To see the unit dimensions of each size, click the "Unit Size" in the left column.
* Ratings are based on servo operation and 12,000 hours running at rated torque. For continuous operation, thermal limitations must be considered, please consult the factory. Peak torque values are based on the ultimate strength of the gear teeth. Information is subject to change without notice.
** C.D. = Center Distance of reducer, which is the vertical distance from the input shaft to the output shaft.
