An integrated nut is installed on the output carrier of the planetary gearbox to eliminate axial clearance. The front and rear bearings are distributed over a large span inside the solid gearbox housing, forming an ultra-strong integrated structure that provides high torsional rigidity, extremely strong radial load capacity, and excellent axial load capacity. A time and finishing machining process is adopted to ensure extremely high coaxiality.Gearbox outline drawingMain technical parameters:StageFirst stageSecond stageThird stageReduction ratio3/4/5/7/1012/16/20/25/28/35/40/50/7080/100/125/140/175/200/250/700/1000Body length112128144Max radial force400N500N800NMax axial force300N390N700NFull load efficiency≥96%≥94%≥90%Weight1.2kg1.5kg1.8kgService life≥20000h≥20000h≥20000hRated input speed3000rpm3000rpm3000rpmMax input speed8000rpm8000rpm8000rpmMotor power400W400W400WGear accuracy class6 GB/T10095 – 20086 GB/T10095 – 20086 GB/T10095 – 2008Operating temperature–25° ~ +90°–25° ~ +90°–25° ~ +90°Protection levelIP65IP65IP65Lubrication methodLong-life lubricationLong-life lubricationLong-life lubricationMounting methodFlangeFlangeFlangeCategory: GearboxTag: AC servo motor and driverBrand: Siheng MotorModel: PF60 Standard SeriesKey Features / Technical Specifications:Integrated nut on output carrier eliminates axial clearanceFront and rear bearings distributed over a large span for high rigidityUltra-strong integrated structureHigh torsional rigidityExcellent radial and axial load capacityHigh coaxiality ensured by advanced machiningReduction ratios: 3/4/5/7/10 (1st), 12/16/20/25/28/35/40/50/70 (2nd), 80/100/125/140/175/200/250/700/1000 (3rd)Body length: 112/128/144 mmMax radial force: 400/500/800 NMax axial force: 300/390/700 NFull load efficiency: ≥96%/≥94%/≥90%Weight: 1.2/1.5/1.8 kgService life: ≥20000 hRated input speed: 3000 rpmMax input speed: 8000 rpmMotor power: 400 WGear accuracy class: 6 GB/T10095 – 2008Operating temperature: –25° ~ +90°Protection level: IP65Lubrication: Long-life lubricationMounting: Flange
