Bard 8602-121BX is an OEM 180 in-lb actuator used to drive and position damper linkages in Bard ventilation and economizer style assemblies on select Bard wall-mounted HVAC equipment. This boxed replacement actuator is built for dependable torque output and repeatable damper movement, helping restore proper outdoor air control and system operation when an original actuator is weak, sticking, or failed. Because actuators can vary by torque rating, wiring, and stroke or rotation requirements, confirm the full unit model and economizer or ventilator option before ordering to ensure correct fit and control compatibility.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
