3/8''-7 Sprocket: The "Precise-Tooth Power Wheel" for Chain-Driven Equipment

Power transmission efficiency of chain-driven equipment depends on precise meshing between sprocket and chain, and the 3/8''-7 sprocket becomes a core accessory with "high-strength material + precise tooth shape". Made of high-strength alloy casting, its surface hardness is 40% higher than ordinary sprockets, resisting heavy-load cutting torque of chainsaws and other equipment. The 3/8'' pitch and 7-tooth design precisely match the pitch of the same-spec drive chain, with meshing gap controlled within 0.1mm to avoid chain skipping or jamming; the size parameters marked on the surface facilitate quick matching of equipment models, and installation only requires slipping onto the drive shaft and fixing—simple operation. Whether for high-speed cutting operation of 5800-series chainsaws or continuous running of small chain-driven agricultural machinery, this sprocket stably transmits power. With high wear resistance, precise meshing, and easy installation, it becomes the "precise-tooth power wheel" for chain-driven equipment.
