Spring Brake Actuator Service Replacement Part Numbers
The following table contains universal service part numbers for Bendix® Spring Brakes. To identify a service
replacement part number, identify the chamber size, stroke length, and the push rod length required for the
application. Port locations and clamp ring orientation can be adjusted by following the clocking guidelines outlined
in the installation instruction sheet included with the actuator. Caution: Do not attempt this adjustment
procedure until you have read and thoroughly understand the recommended guidelines. Failure to do
so could result in bodily injury or death.
For your convenience, shipping information such as caging and pallet quantity are also included. See page 2
for piggyback units and piggyback kits.
