Boneng PS Planetary Slewing Gearbox

Boneng PS Planetary Slewing Gearbox is a core transmission component tailored for slewing mechanisms, integrating precision engineering and robust manufacturing to meet the high-stability, heavy-load requirements of industrial rotary operations. As a specialized variant for rotary equipment, it inherits Boneng’s mature planetary transmission technology while optimizing structural details for slewing-specific working conditions, such as continuous circumferential rotation, uniform load distribution, and high-precision positioning.

The gearbox adopts an optimized precision planetary transmission structure, with key components made of high-strength alloy steel. Sun gears and planet gears undergo deep carburizing, quenching, and precision grinding processes, achieving superior tooth surface hardness, wear resistance, and minimal backlash—essential for accurate slewing positioning. The reinforced planet carrier, designed via finite element analysis, enhances structural rigidity, evenly distributes load pressure, and improves resistance to cyclic fatigue from continuous rotation.

In performance, the PS series boasts single-stage efficiency over 97%, with a flexible transmission ratio range (3-12 for single stage, extendable via multi-stage combinations) to match diverse slewing speed and torque demands. Its compact design delivers high power density, fitting seamlessly into limited installation spaces of rotary equipment. Imported high-precision roller bearings and multi-layer sealing structures ensure low-noise operation, reliable dust and moisture resistance, and reduced maintenance in harsh industrial environments.

With 95% modularization, the gearbox supports flexible customization, including various mounting modes, input/output interfaces, and matching with servo or hydraulic motors. It is widely applied in construction machinery (excavators, cranes), port equipment, wind turbines, and industrial rotary platforms, adapting to complex working conditions such as heavy load, continuous operation, and outdoor exposure.

Backed by Boneng’s professional technical support and global service network, the PS Planetary Slewing Gearbox provides stable, precise, and durable transmission solutions for rotary industries, safeguarding efficient and reliable operation of key equipment.
