The Belimo ZG-LMSA-1/2-5 is a 5-inch shaft extension accessory designed to work with Belimo LF and LM series actuators. This precision-engineered component allows installers to bridge the gap between an actuator and a valve or damper shaft when standard mounting reach is insufficient, making it an essential solution for tight mechanical rooms, deep-set valve bodies, or custom installation configurations.
Product Overview
Manufactured by Belimo — the global leader in actuator and valve technology — this shaft extension is built to the same exacting standards as Belimo’s full actuator lineup. The 1/2″ outer diameter (OD) ensures a secure, precise fit on compatible LF and LM series actuator shafts, minimizing play and maintaining accurate torque transfer throughout the actuator’s full range of motion.
