Features of PHQK-EZ angular servo gearmotor

• Compact and highly dynamic thanks to direct mounting of the servo motor on the gearbox

• Output shaft as a rotary flange shaft

• Quiet operation due to helical gear teeth

• Precise – available with standard or reduced backlash

• Positioning accuracy – fractional gear ratios eliminate positioning errors

• Maintenance-free – no oil changes required

• Customizable mounting position at the time of order

• Ambient temperature: 0 °C to 40 °C (other ranges on request)

• Filled with synthetic grease CLP HC ISO VG 150

• Maximum allowable gearbox surface temperature: 80 °C

• Protection class: IP65

• Standard output shaft sealing: NBR

• For >60% duty cycles or higher ambient temperatures, FKM radial shaft seals recommended

• Housing: Cast iron, painted black RAL9005 (other colors on request)
