German SEW R Series Inline Helical Gearbox

Technical Specifications of the German SEW R Series Gearbox

The German SEW R Series inline helical gearbox is designed with a three-stage helical configuration and parallel shafts, achieving an efficiency of up to 96 percent. The input power range for this series varies from 0.12 to 160 kilowatts, while the output torque can reach up to 18,000 newton-meters. Gear ratios from 3.21 to 289.74 are available across different models, allowing precise control in high-performance systems. The gearbox housing is made of high-strength gray cast iron EN-GJL-200, offering excellent resistance to vibration and heat. The high precision of the gear machining minimizes noise and increases the operational lifespan of the power transmission system.

The SEW R gearbox features ball and roller bearings built to DIN standards and a permanent lubrication system, ensuring stable operation in temperatures ranging from -25 to +90 degrees Celsius. Its modular design allows direct connection to SEW electric motors and other IEC-standard motors. Input and output flanges are available in multiple sizes, supporting both horizontal and vertical mounting configurations. The output shaft is manufactured with an h6 tolerance for backlash-free torque transmission. In addition, durable NBR seals prevent oil leakage under demanding operating conditions.
