A gear system (20, 120), such as for use in a wind turbine (10), is disclosed. The gear system (20, 120) includes a carrier (24, 124), a gear defining a central axis (40, 140), and a pin (50, 150) extending along the central axis (40, 140) and coupling the gear to the carrier (24, 124). The gear system (20, 120) further includes a roller bearing (202) surrounding the pin (50, 150), the roller bearing (202) comprising a plurality of roller elements (206), and a journal bearing (204) surrounding the pin (50, 150).
