Product Overview

The FE Precision Planetary Gearbox is designed for motion control applications that require exceptional accuracy, long-term reliability, and quiet operation. With its helical gear design, the FE series provides smoother transmission and significantly lower noise compared to straight-tooth gearboxes. Backlash is controlled below 3 arc-minutes, ensuring precise positioning and repeatable accuracy, especially in high-dynamic servo systems. The FE Precision Planetary Gearbox strictly complies with ISO 1328 – 1:2013, the international benchmark for gear accuracy defined by the International Organization for Standardization. 

The integrated ball-bearing structure enhances torsional rigidity to 50 Nm/arcmin (FE160 model), enabling stable torque output even during rapid acceleration/deceleration cycles. Paired with high-viscosity synthetic grease that retains lubricity across -25℃~+90℃ operating temperatures, the gearbox achieves zero grease leakage and requires no maintenance for its entire 20,000-hour service life—lowering total ownership costs for industrial users.

Its compact size, high torque density, and universal motor-mounting interface allow seamless integration with major servo motors. The FE Precision Planetary Gearbox is widely used in automation systems, robots, CNC machines, laser processing equipment, and new-energy solutions where precision, efficiency, and durability are essential.

Key Features

  • Ultra-Low Noise
    Helical gears provide smooth and quiet operation, minimizing vibration during high-speed motion. Our helical gear design achieves ultra – low noise performance that meets the measurement requirements of ISO 1329:2013. In no – load tests at 3000rpm, the noise level is as low as 62 dB(A), fully aligning with the standard’s guidelines for noise testing of epicyclic gearboxes. 
  • High Precision
    Backlash ≤3 arcmin (P1 grade) and ≤7 arcmin (P2 grade) ensures precise positioning, minimizing cumulative error in multi-axis motion systems (e.g., laser marking machines).
  • High Rigidity and High Torque Capacity
    Integrated bearing design supports radial loads up to 6520N (FE160) and axial loads up to 3260N, handling heavy-duty tasks like robotic arm lifting or CNC cutting.
  • Easy Motor Installation
    Universal flange (compatible with Siemens, Panasonic, Yaskawa servo motors) and standardized connector structure cut installation time by 50% compared to custom gearboxes.
  • No Grease Leakage
    High-viscosity synthetic grease prevents oil separation, ensuring clean, consistent lubrication. The high – viscosity synthetic grease we use fully complies with ISO 281:2007, which specifies lubrication requirements for industrial gearboxes, including viscosity ranges and high – temperature stability. This ensures zero grease leakage even at 90℃. For lubrication standard details, visit: ISO 281:2007 Lubrication Requirements.
  • Maintenance-Free
    No lubrication replacement is required for the entire service life.
