Planetary servo-gearbox MYB series

1000 - 5000 Nmcompactsingle-stage

Introduction
HONPINE MYB Series planetary gearboxes provide a practical motion‑control solution for general industrial automation. Available in seven frame sizes (MYB042 to MYB220), the range supports a wide span of reduction ratios and rated output torques up to 2000 N·m, making it compatible with many servo motor systems and power transmission applications.

Key specifications

• Frame sizes: 42 mm (MYB042) to 220 mm (MYB220)
• Rated output torque: up to 2,000 N·m (depending on size and ratio)
• Reduction ratios: typical range 3–100 (single‑ and two‑stage)
• Backlash: ≤5 arcmin (single‑stage), ≤7 arcmin (two‑stage)
• Efficiency: ≥97% (single‑stage typical), ≥94% (two‑stage typical)
• Protection class: IP65; Lubrication: synthetic grease (factory filled)
• Operating temperature: -10℃ to +90℃
• Rated input speed (examples): up to 5,000 rpm (smaller frames); maximum up to 10,000 rpm for smallest frames

Typical applications

• Conveyors
• Packaging machines
• Assembly equipment
• Printing machinery
• General industrial automation requiring compact, economical motion control
