Product Features
The flexible options of shaft, for instance a hollow shaft, is possible to apply to different appliances.
The space-saving KHT series can be used to precision positioning or reciprocating device which in limited space and
can output power stably to automated equipment which is operating in minimum vibratility.
Such as packaging machines, dispenser or gentry robot, spring machine industry, LCD inspection equipment,
connected ball screw transmission mechanism… and so on.
 
kht applications

Backlash: L0--> 6 arcmin; L1--> 8 arcmin; L2--> 10 arcmin
Nominal output torque: 15~114 N-M
Output Power: 0.1~2 KW

** Please do not knock the output shaft or any part of gearbox of KHT series **

Reducer Ratio with 1-Stage (L1) = 1st Stage Gear Ratio
Reducer Ratio with 2-Stage (L2) = 1st Stage Gear Ratio x 2nd Stage Gear Ratio
ex. : 1-Stage (L1) Reducer Ratio 5:1 = 1st Stage Gear Ratio 5 = 5
ex. : 2-Stage (L2) Reducer Ratio 50:1 = 1st Stage Gear Ratio 5 x 2nd Stage Gear Ratio 10 = 50
