Various embodiments of conveyor system devices, such as sprockets and idlers, are disclosed. The conveyor components can comprise axial and/or radial openings that facilitate the discharging of debris and other contaminants, which can reduce wear and/or prolong component life. In some embodiments, the conveyor component ramps convey the debris and contaminants to the openings.
