Lenze G500-S Shaft-Mounted Helical Gearboxes

Lenze G500-S is a high-performance shaft-mounted helical gearbox, specialized for industrial transmission scenarios requiring space-saving installation and heavy-duty reliability. As a pivotal model in Lenze’s G-series, it features a hollow-shaft design that directly mounts on the working machine spindle, eliminating the need for additional bases and becoming a preferred choice for conveyors, scrapers, and material handling equipment worldwide.

Boasting a versatile performance range, the G500-S series supports motor power from 0.75kW to 45kW, output torque up to 9500Nm, and transmission ratios spanning 2.8:1 to 394.69:1 via single, dual, or triple-stage configurations. Its core hard-tooth-surface helical gears (ISO 6 precision grade) are made of 20CrMnTi alloy steel, undergoing carburizing and quenching (HRC 58-62) for enhanced wear resistance, achieving a transmission efficiency of 94%-97% and a rated service life of over 15,000 hours.

The shaft-mounted design reduces radial installation size by 40% compared to traditional pedestal gearboxes, ideal for space-constrained layouts. It adopts a torsionally rigid cast iron housing, with standard IP65 protection and optional IP66/IP67 upgrades to resist dust, splashing water, and harsh conditions in metallurgy, mining, and port industries. A 360° rotatable torque arm enables flexible horizontal and inclined mounting, adapting to diverse equipment angles.

Compatible with IE2/IE3 efficiency-class motors, it integrates seamlessly with variable speed drives for precise speed regulation. Equipped with lifelong synthetic lubrication and sealed bearings, it minimizes maintenance needs and operational costs. Optional shrink disk connections enhance shaft coupling reliability, ensuring stable operation under impact loads. Widely used in conveyors, hoists, and roller tables, it embodies Lenze’s engineering excellence in efficient, durable power transmission solutions.
