Stoeber C-EZ helical servo gearmotor

C-EZ helical servo gearmotor

Features of C-EZ helical servo gearmotors

• Compact and highly dynamic thanks to direct mounting of the servo motor to the gearbox, without adapter or coupling.
• High precision with low standard backlash.
• Fractional gear ratio ensures no positioning errors.
• Low-noise operation with helical gear teeth.
• Maintenance-free, no oil changes required.
• Lubricated for lifetime operation.
• Mounting position to be specified when ordering.
• Output shaft: solid shaft with keyway.
• Ambient temperature range from 0°C to 40°C (other temperature ranges available on request).
• Filled with synthetic lubricant CLP HC ISO VG 150.
• Mineral oil for food, beverage, and pharmaceutical industries available on request.
• Maximum permissible gearbox temperature (on the gearbox surface) ≤ 80°C.
• Protection class IP65, optionally IP66.
• Standard output seal NBR, optionally FKM.
• For duty cycles above 60% and higher ambient temperatures, FKM radial shaft seals on the output are recommended.
• Cast iron gearbox housing.
• Optional direct mounting of STOBER EZ/LM servo motors without adapter, coupling, or double brake.
• Standard paint finish black RAL 9005 (other colors available on request).
