or other liquids

Note

On rare occasions, grease may ooze out from the gearhead. If there 

is a concern over possible environmental damage resulting from the 

leakage of grease, provide an oil tray or similar oil catching mechanism 

in order not to cause a secondary damage. Grease leakage may lead to 

problems in the customer's equipment or products.

Note

Do not install the motor to the mounting hole diagonally or assemble 

the motor forcibly. Doing so may cause damage to the motor.

Removing/Installing the gearhead

See the following steps to replace the gearhead or to change the outlet 

position of the lead wires and the position of the terminal box.

Removing the gearhead from the motor

Remove the hexagonal socket head screws (2 pieces) 

assembling the motor and gearhead and detach the 

motor from the gearhead.

Installing the gearhead to the motor

1. 

Keep the pilot sections of the 

motor and gearhead in parallel, 

and assemble the gearhead with 

the motor while slowly rotating it 

clockwise/counterclockwise.

At this time, note so that the pinion 

of the motor output shaft does not 

hit the side panel or gears of the 

gearhead strongly.

2. 

Check no gaps remain between the 

motor and gearhead, and tighten 

them with hexagonal socket head 

screws (2 pieces).

Note

 

Do not forcibly assemble the motor and gearhead. Also, prevent 

metal objects or foreign substances from entering in the gearhead. 

The pinion of the motor output shaft or gear may be damaged, 

resulting in noise or shorter service life.

 

Do not allow dust to attach to the pilot sections of the motor and 

gearhead. Also, assemble the motor and gearhead carefully by not 

pinching the O-ring at the motor pilot section. If the O-ring is crushed 

or severed, grease may leak from the gearhead.

Rround shaft type

Secure the motor with hexagonal socket head screws (not supplied) through 

the four mounting holes provided. Do not leave a gap between the motor and 

mounting plate.

Motor with cooling fan

When installing a motor with cooling fan onto a device, leave 10 mm (0.39 in.) 

or more behind the fan cover or open a ventilation hole so that the cooling 

inlet on the back of the motor cover is not blocked.

 

z

Mounting the capacitor

Mount the capacitor securely by using M4 screws 

(not provided).

Ø4.3 mm

(0.169 in.)

Note

 

Do not let the screw fastening torque exceed 1 N·m (8.8 lb-in) to 

prevent damage to the mounting foot.

 

Mount capacitor at least 10 cm (3.94 in.) away from the motor. If it 

is located closer, the life of the capacitor will be shortened.

Installing a load

The gearhead shaft is provided with a key slot 

for connecting the transmission parts. When 

connecting the transmission parts, ensure 

that the shaft and parts have a clearance fit, 

and always fix the parallel key to the output 

shaft with a screw to prevent the parts from 

rattling or spinning.

Note

Do not apply excessive force onto the output shaft of the gearhead 

using a hammer or other tools. Doing so may cause damage to the 

output shaft or bearings.
