Push rod length ‘A’ is 

measured from the 

bottom of the actuator 

to the end of the push 

rod.  This dimension is 

taken with the spring 

brakes released or 

caged. 

These heavy-duty push rods are manufactured from steel rods with an original diameter of 0.625 inches over the 

full length prior to threading.  Standard push rods are manufactured from steel rods that are only 0.581 inches 

in diameter.  As a result, the heavy-duty push rods are approximately 20% stronger than the standard push rod. 

In demanding applications, the heavy-duty push rod resists bending forces (system deflection), is more responsive 

and out-performs the standard rod versions available in the industry.  In addition, Bendix heavy-duty rods are 

engineered to meet or exceed the requirements specified for all commercially available slack adjuster suppliers 

as of August 2011;  Not all standard rod actuators meet these requirements.
