Minimum dimension and maximum dimensions are measured from clevis eye to clevis
eye. Use these formulae to calculate the dimensions.
Minimum = Rise” + 14.13”
Maximum = (Rise” x 2) + 14.13”
View A
This is a view of the brake assembly
installed from the motor end with one
coupling half. It is the view looking into
the lower housing before the motor
coupling half or rubber grommet is
assembled.
When properly assembled, this
coupling will not rotate in the CW or
the CCW direction. This braking action
allows the actuator to hold position
when the motor is stopped
.
View B
This is a view of the installed brake
assembly from the motor end with
both coupling halves shown.The
unshaded coupling tangs are the
motor half coupling.
When properly assembled, this
coupling half will rotate in both the
CW and CCW direction. This allows
the motor to be reversed
.
