  "textContent": "A pneumatic brake actuator has a housing and a divider that divides the housing into a spring chamber (58) containing a spring (62) and a pressure chamber (56). The divider has an opening that receives an end of an actuator tube (82). A bearing (94) that is positioned within the opening in the divider is joined to both the divider and the actuator tube. A caging bolt (122) has a first end positioned within the actuator tube and extends from the first end through openings in the bearing and housing to a second end positioned outside of the housing. The connection between the bearing, divider and actuator tube contains the spring within the housing in the event that the housing and/or divider fails. The divider can be a piston (202) or a diaphragm (32) and pressure plate (60). The bearing can be joined to either of the divider and actuator tube with threads and/or by welding.",
