Shandong Hengji SD320 Planetary Gear for Dozer Transmission

This planetary spur gear is a core transmission spare part independently developed and produced by Shandong Hengji Group, perfectly compatible with the gearbox of our 1.5-ton to 5-ton electric and diesel forklifts. Unlike most forklift manufacturers that outsource gear accessories, we build a complete closed-loop production line for gear processing, covering forging, CNC precision cutting, carburizing heat treatment and finished product inspection, with 25 proprietary patents for gear manufacturing technology to guarantee stable and consistent quality.
High-strength alloy steel is selected as raw material for this planetary spur gear. After standardized carburizing and quenching heat treatment, the gear tooth surface achieves ultra-high hardness to resist long-term friction and abrasion, while the gear interior retains strong toughness to buffer instant heavy impact generated during frequent loading, unloading and climbing. It effectively avoids common failures such as tooth breakage, surface pitting and gear deformation. Compared with generic aftermarket replacement gears, its service life is extended by 30%, which greatly reduces customers’ frequent replacement costs and equipment downtime.
The gear adopts precision straight-tooth design with multiple fine machining processes to control strict tooth profile tolerance. It realizes tight and uniform meshing inside the gearbox, delivering efficient power transmission and low running friction loss. The smooth inner bore is processed with high precision to fit shafts closely without shaking or slipping under full-load working conditions. This gear can reliably cope with harsh working environments including logistics warehouses, ports, mining yards and construction sites with continuous high-frequency operation.
Every finished gear undergoes full inspection procedures before delivery, including dimensional measurement, hardness test and meshing matching test to eliminate unqualified products. We support customized inner bore diameter, tooth quantity and outer size, and accept OEM & ODM orders for global brand partners. All products pass ISO9001 quality system certification and CE export certification, satisfying customs clearance standards of Europe, Southeast Asia, the Middle East, Russia and Latin America.
We keep abundant stock of standard planetary spur gears for fast delivery. As an integrated forklift and core component manufacturer, we provide long-term stable spare parts supply for global forklift distributors, equipment rental companies and maintenance stores. Choosing our self-produced planetary gears brings you durable quality, sufficient inventory and lower overall operation costs for your forklift business.
