Bard 921-0105BX - Belimo actuator assembly
Bard part number 921-0105BX is an OEM actuator assembly supplied as a boxed Belimo unit used in Bard wall mounted HVAC equipment to position an air control damper as the control system calls for ventilation, economizer operation, or outside air changes. When an actuator starts slipping, sticking, or failing to drive the damper, it can cause poor ventilation control, comfort issues, and nuisance alarms, so replacing it with the correct Bard specified assembly helps restore proper damper movement and dependable operation. Because actuators are selected for specific torque, rotation, and control signal requirements, confirm your unit model and the existing actuator details before ordering to ensure correct fit and wiring match.

What does the "BX" suffix mean?
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.
