Series

EWJMK・EWMK:This model is primarily for foot mounting. This specifies the EWJMK Series for sizes 70 or smaller, and the EWMK Series for sizes 80 or above.

SWJMK・SWMK:This model is primarily for flange mounting or shaft mounting. This specifies the SWJMK Series for sizes 70 or smaller, and the SWMK Series for sizes 80 or above.

Size

This indicates the size of the gear reducer.

Mounting Position

E  or  T:E: On this type, it can be mounted in any direction. (Applies to EWJMK and SWJMK Series)
T: On this type, the input shaft is located above the output shaft. (Applies to EWMK and SWMK Series)

B: On this type, the input shaft is located below the output shaft.

V: On this type, the output shaft is vertical.

Refer to the diagram below for details.

Reduction ratio

This indicates the reduction ratio.

Shaft Arrangement

This shows the relation of the input and output shafts to the mounting surface.

Refer to the diagram below for details.

Mount code

Specify the mount code that corresponds to the motor to be mounted.
