• Fractional gear ratio ensures no positioning errors.
• Maintenance-free – no oil changes or servicing required.
• Low-noise operation with helical gears, max. 59–64 dB.
• Low moments of inertia.
• Rigid output bearing due to preload.
• Continuous operation without additional cooling.
• Ambient temperature from 0°C to 40°C (other temperature ranges on request).
• Maximum gearbox housing temperature ≤ 90°C.
• Protection class IP65.
• Any mounting position.
• Synthetic gear oil CLP HC ISO VG 150.
• One primer paint coat in RAL 7001 or RAL 9005.
• Radial shaft seals: FKM on input / NBR on output.
• For duty cycles > 60% and higher ambient temperatures, FKM radial shaft seals on the output are recommended.

Optional versions of PHQ-EZ planetary servo gear motors
