Why Choose This Configuration?

Buyers generally choose this lower-ratio configuration where they want to keep more output speed while still gaining useful reduction and torque multiplication. It is well suited to conveyor, transfer, packaging, and handling drives where faster shaft speed is preferred over very high reduction.
