Siemens LBRS180 Long Rotary Shaft 180mm

Product Description

The SIEMENS LBRS180 is a long rotary shaft extension designed for use with compatible Siemens rotary actuators. Measuring 180mm in length, this shaft accessory allows technicians to reach valve stems or damper shafts in installations where standard-length shafts fall short. It is a precision-fit mechanical component intended for HVAC control applications, including VAV systems, air handling units, and zone damper assemblies. Licensed HVAC technicians and controls specialists are the primary installers. The part weighs 0.044 pounds and has an overall footprint of 1.6 inches by 0.5 inches by 0.3 inches.

This shaft extension is used in commercial and residential HVAC control applications where Siemens rotary actuators are installed on dampers or valves that require extended reach. It is suited for retrofit and new-construction scenarios where actuator-to-valve alignment requires additional shaft length to complete the mechanical linkage. No specific compatible model numbers were provided in the product data.
