This flanged internal ring gear is a heavy-duty core transmission component independently designed and fully produced by Shandong Hengji Group, specially customized to match wheel-side planetary reducers of our 1.5–5 ton electric and diesel forklifts. Unlike most forklift brands that source gear accessories externally, we operate a complete closed-loop gear production workshop, covering forging, CNC internal tooth precision processing, carburizing quenching heat treatment, flange hole drilling and finished product comprehensive testing. We own 25 independent patents for gear manufacturing technology, so every batch of products maintains consistent stable quality without supply chain risks.
High-strength alloy steel is selected as raw material for this ring gear. After standardized carburizing and quenching treatment, the inner helical tooth surface gains ultra-high hardness to resist long-term friction and abrasion under heavy load, while the gear base retains strong internal toughness to buffer huge torque impact generated during frequent cargo lifting, transportation and ramp climbing. It effectively solves common failure problems such as tooth surface pitting, tooth fracture and gear ring deformation. Compared with ordinary aftermarket replacement ring gears, its service life is extended by 30%, cutting customers’ repeated replacement costs and production shutdown losses greatly.
The product adopts precision internal helical tooth structure processed by multiple CNC grinding procedures, with strictly controlled tooth profile tolerance. It achieves full uniform meshing with planetary gears inside the reducer, delivering smooth low-noise power transmission and low energy loss. The integrated outer flange is pre-machined with standard mounting holes, ensuring quick positioning and firm assembly without offset or looseness during continuous high-frequency operation in warehouses, ports, mines and construction yards.
Each finished flanged internal ring gear undergoes strict full inspection before shipment, including roundness detection, tooth hardness test, meshing matching test and flange hole position calibration to screen out all defective goods. We support customized inner/outer diameter, tooth quantity, flange size and thickness, and accept OEM & ODM orders for global distributors. All products pass ISO9001 quality system and CE export certification, meeting customs clearance standards of Europe, Southeast Asia, Middle East, Russia and Latin America.
We keep abundant stock of standard flanged ring gears for fast delivery. As an integrated manufacturer of forklifts and core spare parts, we provide long-term stable spare parts supply for forklift dealers, equipment rental companies and maintenance shops worldwide. Choosing our self-produced flanged internal ring gears brings you reliable durability, sufficient inventory and lower comprehensive operation costs for your forklift business.
