AUMA Z045.821 Gearbox | Worm Gear Set, High Ratio, Cast Iron, for Valve Actuator Drive

AUMA Z045.821 specifications. Worm gear set, high reduction ratio, cast iron, for integration into AUMA valve actuators.

Product Overview

The AUMA Z045.821 is a worm gear set, a key mechanical component designed for integration into AUMA electric multi-turn actuators. It provides a high reduction ratio to convert the high-speed input from the actuator motor into the high-torque, low-speed output necessary for operating industrial valves. Featuring a robust cast iron housing and lifetime lubrication, it is engineered for reliable, maintenance-free, and long-term performance in demanding valve automation applications.
