Die Forging S355 St52 Finish Maching OD 4000mm Forging Steel Gear Blanks
We are specialized in manufacturing different type of large mechanical products according to engineer drawings.
The products include gears, pinions, sprockets, shafts, wheels, rollers, couplings, pulleys, housings ,frames, molds, nonstandard machinery parts, wear resistant parts and structural components.
Gear transmission refers to the device that transmits motion and power from the gear pair. It is the most widely used mechanical transmission method in modern equipment. Its transmission is more accurate, high efficiency, compact structure, reliable operation and long service life.Our gears can be heat treated, hardened, oil immersed according to customer needs.The gear is widely used in industry, vehicle, power tools, motor, bicycle, electrombile.
