The STH servo-driven output rotary actuator sets a new price/performance point in rotary positioning. The company’s Able servo reducer connects the actuator and servomotor. The servo reducer offers simple mounting of small-to-medium servo motors and gives the complete STH package net ratios ranging from 12:1 through 324:1.

The STH’s very large crossed-roller output bearing offers impressive thrust loads and tilting moments. A hollow through-bore allows wiring or tubing to be passed through to effectors, fillers, or other active machinery.
