FS120 Gearbox: The "High-Torque Precision Transmission Core" for Heavy-Duty Equipment

The high-torque demand of FS120-series heavy-duty equipment has strict requirements for the gearbox’s "precision + durability", and the FS120 gearbox is just suitable for this scenario. Its sealed aluminum alloy body, with IP54 protection rating, can handle complex outdoor conditions such as dust and spray, avoiding rust and jamming of internal gears. Internal steel gears are carburized and quenched, with surface hardness over HRC58—wear resistance is 45% higher than ordinary steel gears; meshing gap is controlled within 0.018mm, transmission efficiency up to 96%, reducing energy loss by 12% compared to similar gearboxes. The "installation direction arrow" and "anti-loosening mark" marked on the top make installation more precise and operation more stable. Whether for high-load cutting of FS120 professional trimmers or continuous operation of the same-model heavy-duty equipment, this gearbox stably transmits high-torque power. With high protection, high wear resistance, and high transmission efficiency, it becomes the "high-torque precision transmission core" for heavy-duty equipment.
