Proportional solenoids have low friction bearings formed by molding a pair of annular bearings in imprecise grooves formed in armatures so that radially outer surfaces of the bearings have a precise and low friction fit within precision machined interiors of solenoid housings. The bearings can be formed on body or push rod portions of the armatures and can have different outside diameters that are formed in a single precision mold to ensure concentricity and accuracy without requiring precision machining of armature or bearing surfaces.
