Shanghai guzuo R series helical gear reducer is a coaxial inline hard-tooth surface gearbox with

horizontal transmission structure. Adopting high-precision hardened helical gears and integrated

cast iron housing, this reducer features high transmission efficiency, stable operation, low noise and

compact coaxial layout. The carburized and quenched alloy steel gears provide excellent wear resistance and impact resistance. It is the most widely used general-purpose reducer for straight-line power

transmission in heavy-duty industrial machinery.

Main Features

• Coaxial Inline Structure:

  Straight-line coaxial design simplifies mechanical layout, saving installation space for inline

  transmission equipment.

• Hardened Helical Gears: Alloy steel gears undergo carburizing quenching and precision grinding, with high hardness and long service life.

• Strong Bearing Capacity: Thickened cast iron housing and reinforced gear shaft improve torsional rigidity for heavy-load continuous operation.

• Low Vibration & Quiet Running: Optimized gear meshing process ensures smooth rotation and low operating noise.

• Flexible Installation: Optional foot-mounted and flange-mounted types to meet various on-site installation requirements.

• Excellent Sealing Property: Premium sealing structure effectively prevents oil leakage and dust ingress, reaching IP55 protection grade.
