Gears & Pinions

Yile Machinery manufactures a full spectrum of heavy-duty industrial gears and pinions for rotary kilns, ball mills, crushers, and other critical heavy equipment. Our gear manufacturing capabilities cover modules from M8 to M55 and diameters up to 12 meters, with materials including cast steel (ZG45, ZG42CrMo), forged alloy steel, and bronze alloys.

Our in-house gear cutting, hobbing, and grinding equipment ensures precise tooth profiles that meet DIN, AGMA, or ISO standards. Each gear undergoes full non-destructive testing and dimensional inspection before delivery.

We support single-piece and small-batch production, making us the ideal partner for replacement parts, equipment upgrades, and new OEM projects. Send us your drawings or specifications to receive a detailed quotation.
