Coding system
• Various types of gear heads are available.
• The X type is available in a metal bearing model and or a ball bearing type.
• The P type (90 mm sq. only) is high torque type: its maximum permissible shaft torque is 29.4 N·m (300
)
• 22 reduction ratios from 1/3 to 1/180 are available for the X type; 23 reduction ratios from 1/3 to 1/200 are
available for the Y and Z types.
When the decimal gear head (reduction ratio: 1/10) is used, a reduction ratio of up to 1/1800 (1/2000 for the Y and
Z types) can be attained.
• The X type and Z type of 90 mm sq. are available in right-angle type.
• Gear heads dedicated to C&B motors are available. The gear heads will withstand 2 million start and stop cycles.
For allowable gear head permissible torque, see C&B motor (p. B-348).

Outline of gear head
Maximum permissible torque
Nominal reduction ratio and actual reduction ratio
There is a limit to the strength of a gear due to its material and construction. The usable load torque determined
based on this limit is called permissible torque. As can be seen from the above-mentioned formula, the load
becomes larger when the reduction ratio is increased. If the gear head is used with the load exceeding the
permissible torque, its life expectancy will be shortened significantly. Refer to the following graph and the
permissible torque for each model and use the gear head at an appropriate load.
Note that there is a difference between the nominal reduction ratio and actual reduction ratio of each gear head.
Refer to the table below. When using the gear head, calculate the speed based on the actual reduction ratio.
* Gear heads dedicated to C&B motors have the same nominal reduction ratio and actual reduction ratio. Example:
nominal reduction ratio 1/3; actual reduction ratio 1/3
For practical use, calculate the speed based on the actual reduction ratio.

The overhung load is defined as a load applied to the output shaft in the right-angle direction. This load is
generated when the gear head is coupled to the machine using a chain, belt, etc., but not when the gear head is
directly connected to the coupling. As shown in the figure below, the permissible value is determined based on the
load applied to the L/2 position of the output shaft.
The thrust load is defined as a load applied to the output shaft in the axial direction.
Because the overhung load and thrust load significantly affect the life of the bearing, take care not to allow the load
during operation to exceed the permissible overhung load and thrust load shown in the table below.

* When the decimal gear head is used, the total efficiency is the product of gear head efficiency and decimal gear

Gear head efficiency and ambient temperature
Torque reduction ratio
Calculate the actual gear head efficiency by multiplying the above-shown gear head efficiency at room temperature
by the torque reduction ratio shown below.

Service factor
Life expectancy of motor varies depending on load fluctuation. To determine the life expectancy, a factor called
service factor, as shown in the table below is used.First choose the appropriate service factor according to the type
of load and multiply the result by the required power to determine the design power.

* Though it seems that the motor can be operated even in overload when the service factor is 0.8, note that the
service factor is defined for the allowable torque of the gear head. If the motor is operated in overload, the life of
insulator may be shortened or the motor may be burned out due to an abnormal temperature rise.

Preparation
DON'T
(1) Prepare a gear head that matches a motor described in this manual.
Use of incompatible gear head will cause malfunction.
Don't touch screws
on the output shaft
of gear head.
Will cause malfunction.
Screws
Considerations for installation of gear head
You may experience a sliping gear contact due to broken pinion tooth, locked gear or leaked grease as the gear
head life comes closer.
Place a safety device to keep safe operation at any time even if such problems take place.
(3) Wipe off any grease on the gear head flange surface.
Assembling
(1) Place the unit so that the motor shaft faces up.
Direction of the motor lead and output shaft of gear head
must match an application.
(2) Do not contact a tooth tip of pinion shaft to a tooth tip of gear
head.
Set each toothes of motor and gear head correctly and
gently press and turn the gear head in counter and counterclockwise.
(3) To attach the gear head to an application, use the "attaching
screws" supplied with the gear head and tighten the screws
with appropriate torque and with care not to pinch the O ring,
so that the there is no gap between motor flange and gear
flange.

<Note>
Do not forcedly assemble the motor and gear head. Do
not damage the tooth of the motor pinion and gear head.
Incorrect assembly results in abnormal noise generation
or shortened unit life.

• Place a drop-proof device in an verticlly motioned application like a lifter.
• Place a device to open the door in a door application just in case the gear head is locked.
• Place an oil pan to prevent oil from coming out in an application like food/textile etc.
• Do not place an encoder, sensor, contact, etc near a gear head where the grease may leaking out. If not, please
have a protection from grease.
• Have a routain check of the gear head to avoid unexpected accident.
<Precautions>
Keep the gear head attached to the motor. Otherwise, the O ring may
become distorted or damaged, causing grease leakage.
• When reassembling, first replace the O ring with a new one.
• When installing a motor associated with the gear head to the application
device, temporarily secure the motor and gear head with a tape until
assembly completes.

Assemble the motor shaft facing up.
Considerations for storage of gear head
When storing the gear head as a single unit, place it with the output shaft facing down.

• These gear heads are designed according to “inch” system.
• All bearings are ball bearing.
• 22 reduction ratios from 1/3 to 1/180 are available for the X type; 23 reduction ratios from 1/3 to 1/200 are
available for the Z types.
When the decimal gear head (reduction ratio: 1/10) is used, a reduction ratio of up to 1/1800 (1/2000 for the Y and
Z types) can be attained.
