Specifications/Overview

■Axis Placement and Rotation Direction

Reducer / Bevel Gear Box Related Image

The phase of the gear is limited, so be sure to check the direction of rotation of the A and B axes.
The direction of rotation can be both forward and reverse, and performance is the same for each.
The rotation direction of the arrows indicates the relationship between the rotation directions of each axis.
The phases of the keyways on each axis do not necessarily match.
When the speed ratio is 2:1, deceleration is performed from axis A to axis B.
