Hanwei is a top industrial gear manufacturer offering premium industrial gear at 20-30% off OEM with a 10yr warranty.

Range of premium products

Custom Industrial Gear Manufacturer & Heavy Transmission Components.

We are a premier industrial gear manufacturer specializing in heavy-duty industrial gear solutions and large-diameter transmission components, with a focus on girth gears up to Φ16m serving ball mills, SAG mills, rotary kilns, and similar heavy rotating equipment across the mining, cement, metallurgy, and energy sectors.

Core Competitive Advantages

We deliver 20–30% cost advantages over equivalent European and Japanese manufacturers, with shorter lead times (up to one-third reduction) and door-to-door logistics support.
Covers gears and ring gears from Φ1m to Φ16m. Our 16m CNC gear grinding machine, paired with a 16m CNC 6‑axis gear hobbing machine, forms a single production line capable of completing the entire girth gear machining process in‑house—a capability shared by very few manufacturers worldwide.
Every step from raw material to finished product is performed under one roof: 120T refining furnace + 80T EAF for casting → vacuum‑degassed forging → 18 heat treatment furnaces (carburizing, nitriding, quenching) → precision machining → on‑line inspection. Full control over critical processes ensures reliable lead times and consistent quality.
Cast / Forged / Cast+Forged+Welded / Forged+Steel Plate Welded — selected based on operating conditions and budget. We never force a one‑size‑fits‑all solution.
Critical operations run on German‑built machinery: NILES 5m CNC gear grinding machine, HOFLER 2.5m CNC gear grinding machine, and Schiess‑Zhuangming 16m 6‑axis gear hobbing machine. Achieves gear accuracy to DIN Grade 6 and surface hardness up to 380HB.
