PG25 Series Gearbox (Ф25mmXLmm )   

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: ≤0.2mm
     6、The gear box can apply to RF-370 motors.
     7、When the motors using at low speed,high gear
       ratio will cause gear motor torque more than 30kgf.cm.At
       this torque the gears will be broken easily.Be noted.
     8、when install the gear motor please don't let the screws go through
       into the gearbox internal more than 4mm.lf so the gearbox will be
       demaged.
