Product Features

KX serial products can be applied to the automated equipment which is in precision
transmission or continuously transmission.  Such as conveyer equipment, pipe bender, spring machine industry, food and packaging machines, wood processing machines… and so on.

Kx series also recommended to customers who try to find the economy reducer for all applications in which a particularly low backlash is not necessarily the main focus.

 

kx applications

Backlash: L1--> 8 arcmin; L2--> 12 arcmin
Nominal output torque: 13~1600 N-M
Output Power: 0.1~15 KW

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
Reducer Ratio with 3-Stage (L3) = 1st Stage Gear Ratio x 2nd Stage Gear Ratio x
3rd 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
ex. : 3-Stage (L3) Reducer Ratio 500:1 = 1st Stage Gear Ratio 5 x 2nd
Stage Gear Ratio 10 x 3rd Stage Gear Ratio 10 = 500
