PLANUREX 2 Standard Series

The PLANUREX 2 Standard Series, a classic planetary gear unit lineup from FLENDER, stands as a global industrial standard for heavy-duty power transmission. With years of verification under harsh operating conditions, it delivers exceptional reliability and stability, making it an indispensable core component in high-torque industrial scenarios.

This series offers 22 size options, covering a nominal torque range of 117,000 Nm to 2,600,000 Nm and a transmission ratio range of 25 to 4,000, enabling precise adaptation to diverse load and speed requirements. Its flexible installation design supports both horizontal and vertical mounting, while the modular structure standardizes key components such as planetary stages, housings, and input/output assemblies, reducing production complexity and ensuring cost-effective batch manufacturing with high quality.

Engineered for performance, the gear unit features hardened and ground sun gears and planet gears, with ring gears subjected to high-temperature quenching and tempering. The low rolling and sliding speeds on tooth flanks enable low-noise operation, while the robust cast iron housing enhances load-bearing capacity and corrosion resistance. It seamlessly combines with upstream helical, worm, bevel, or bevel-helical gear units, expanding its application versatility.

Boasting high efficiency and comprehensive accessory options, it is widely deployed across mining, cement, crane, chemical, and pharmaceutical industries. Typical applications include roller presses, tube mills, rotary kilns, bucket excavators, slewing gear systems, and agitators. As an integrated drive system or standalone unit, it ensures process stability, laying a solid foundation for predictive maintenance and long-term operational cost reduction.
