Shandong Hengji SD320 Planetary Gear for Dozer Transmission

Shandong Hengji forklift transmission gears are core transmission parts compatible with transmissions of various internal combustion forklifts and construction machinery. Forged from high-strength alloy steels 40Cr and 20CrMnTi, the products feature high substrate density and excellent toughness, fundamentally eliminating common defects of ordinary gears such as tooth breakage, severe wear and edge chipping. Processed through precision hobbing, fine grinding and carburizing quenching heat treatment, the gear teeth reach a hardness of HRC 58-62, delivering exceptional wear resistance and impact resistance. They can withstand heavy loads, frequent start-stop cycles and harsh working conditions on construction sites over long periods, with a far longer service life than conventionally machined gears.

Adopting a standard hollow spur gear structure, the products boast precise dimensions and high coaxiality, enabling tight and smooth meshing, stable power transmission, low noise and minimal power loss. They effectively boost the power output efficiency of forklifts, protect integral transmission components and reduce frequent maintenance breakdowns. The inner bore, keyway and end face all undergo fine grinding with tight tolerances, ensuring superior fitting accuracy during assembly, easy disassembly and installation, and broad compatibility with most domestic and imported forklift transmission models.

Our factory integrates forging, machining, heat treatment and inspection on one production line. All products pass flaw detection, full dimensional inspection and hardness testing before delivery, with zero defective goods and no false labeling. We support sample trial orders, bulk purchases and OEM customization, and can manufacture gears of various modules, tooth counts and special specifications according to drawings or samples.

As a direct manufacturer based in Shandong, we eliminate markup from middlemen to offer superior cost performance, stable supply and abundant stock. Choosing Hengji gears can drastically reduce equipment failure rates and after-sales costs, making us a reliable long-term high-quality supply chain partner for foreign trade companies, spare parts wholesalers and repair shops.
