Gearbox Overview

Within the TEC FCNDK series, this version is aimed at machines needing a combination of 56B14 input, 11mm hollow output, and a nominal output speed around 187rpm with a 4 pole motor. The modular format also supports multiple mounting positions including B3, B6, B7, B8, V5, and V6.

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.
