Bonfiglioli SL Series Inline Planetary Gearbox

The Bonfiglioli SL Series Inline Planetary Gearbox boasts distinct advantages, serving as a high-performance precision drive solution for industrial scenarios requiring coaxial torque transmission. Its core strengths lie in excellent load-bearing capacity and positioning accuracy—integrating optimized planetary gear trains with precision-ground gears, it delivers a radial load capacity of 6,000–15,000 N, transmission efficiency up to 97%, and ultra-low backlash (≤6 arcmin for 1-stage, ≤8 arcmin for 2-stage), ensuring stable and precise operation even in high-frequency intermittent duty cycles.

Crafted with a robust housing and hardened alloy steel gears, it offers superior torsional rigidity and wear resistance, withstanding short-term overloads to adapt to heavy-duty demands. Equipped with lifelong synthetic lubrication and a dual-seal system, it achieves an IP54 protection rating, effectively resisting dust and minor moisture while enabling maintenance-free operation for extended periods, reducing operational costs. Available in three sizes (070/090/120) with 1-stage (3–10) and 2-stage (9–100) gear ratios, it covers a nominal torque range of 25–155 Nm, supporting flexible configuration for diverse needs. Its standardized output design ensures seamless integration with servo motors and timing belt pulley systems. Widely applied in belt-driven conveyors, precision automation equipment, and light-duty industrial machinery, it excels in scenarios demanding compact layout, stable load transmission, and accurate positioning. Backed by Bonfiglioli’s professional expertise, it balances reliability, versatility, and cost-effectiveness, becoming an ideal choice for mainstream inline planetary drive requirements. (400 words)
