Direct Coupling
This is the preferred method for mounting
-
FSLF
Note that actuator floats freely. Clamp cold welds
when teeth dig into the damper shaft and the anti-
rotation strap stud allows the actuator to move if
shaft is not perfectly concentric. Rigid mounting by
jamming the stud into the U-slot of actuator is NOT
usually best.
FSLF mounted on the
damper shaft. Two
sheet metal screws hold
the anti-rotation strap.
Two nuts secure cold-
weld clamp onto shaft.
