1 STH-SERIES The STH is a mid-range speed and torque gear reducer that sets a new standard for rotary positioning performance at an exceptional price point. A SHIMPO ABE planetary gearbox is the interface between the servo motor and STH rotary stage. The ABE reducer features simple mounting of nearly any small to medium servo motor, and it gives the complete STH package net ratios ranging from 12:1 through 400:1. The rotary stage has very large crossed roller output bearings, allowing for impressive thrust loads and tilting moments. A generous hollow bore provides clearance for wiring, tubing, or threaded rod to be passed through to effectors, fillers, or any other active machinery. The STH fills the need for a high-performance, price competitive option to your traditional style indexers and cam units. 370
