A bearing assembly for supporting a rotatable component of an electrophotographic image forming device according to one example embodiment includes a metal bearing insert molded into an electrically nonconductive plastic shell. The metal bearing includes a bearing surface that defines a cylindrical opening for receiving an axial end of a shaft. The plastic shell covers an entire outer circumferential surface of the metal bearing and an inner axial side of a portion of the metal bearing forming the opening is inset from an inner axial side of the plastic shell such that the plastic shell shields the metal bearing from electrical arcing.

A printing cartridge including a body, the body having a base and a tower defining a passageway. The tower is made from a first polymer material, and has a proximal end and a distal end. The proximal end is attached to the base. The distal end includes a surface. A frame, made of a second polymer material different from the first polymer material, is attached to the surface of the tower. A filter is attached to the frame and positioned to extend over the passageway.
