Siemens Building Technology ASK71.9 Crank Arm 320734-701 If cleaning doesn't restore atThe Siemens Building Technology ASK71. 9 Crank Arm is a heavy duty mechanical link designed for HVAC damper actuator retrofits and linear to rotary motion conversions. This universal crank arm provides a critical interface for damper shaft coupling in applications where direct ball joint connections are physically restricted or space constrained. Engineered to support Siemens OpenAir actuators, it fits damper shaft sizes ranging from 3 8 to 1 inch (9.
