VF Series Gearbox (69.8mmX76.2mmXH18mm )   

Note:1、Housing material:Zinc alloy.
     2、Backlash,at no-load: ≤2°
     3、Bearing at output: sleeve bearings
     4、Radial play of shaft: ≤0.05mm
     5、Radial play shaft: ≤0.5mm
     6、The gear box can apply to 545,555,YJ61 motors.
     7、When the motors using at low speed,high gear
       ratio will cause gear motor torque more than 90kgf.cm.At
       this torque the gears will be broken easily.Be noted.
