Abstract
A solenoid operated valve has a valve body with a plurality of ports and a spool slideable within the valve body to interconnect the ports in different combinations. An actuator drives the spool into several operating positions. The actuator has a solenoid assembly with an armature that moves within a bore in response to an electromagnetic field. A push member projects from the armature and has a bearing secured thereto. The bearing has a cage that retains a plurality of rollable elements in slots separated by walls that are resilient enabling the rollable elements to be forced into the slots during assembly and thereafter be captured in the cage when the walls return to their original positions. A latch on the cage engages the push member to affix the bearing in place.
