A throttle body (12), for an air intake system of a vehicle, including a housing (14) formed of a thermoplastic material and including a pair of throttle shaft bearing pockets (24, 26) extending from a main bore (16) of the throttle body. The bearing pockets (24, 26) each include a generally cylindrical wall (34) of a diameter to allow for a press fit of throttle shaft support bearings (28, 30) therein. After insertion, a swaging process secures the bearings (28, 30) into the pockets (24, 26) by forming lips (40) around the bearings. The walls (34) may include axial grooves (36) to allow for a more controlled swaging operation.
