Installation direction

Horizontal, vertical, tilt, etc.

Installation environment

• All models have a fully enclosed structure that allows them to be used outdoors. However, even outdoor models require an appropriate cover in adverse environments where they are constantly exposed to water or steam, or in places where snow accumulates. Ambient temperatures vary depending on the conditions of use, but they can generally be used within the range of -15 to 40°C. If they are used above 40°C, be sure to protect them with an insulating cover or similar. Never use in a flammable atmosphere. Doing so may result in an explosion or fire. Also, avoid use in locations where they are subject to vibrations or impacts exceeding 1G.
• ・Please contact us if you wish to use the product in a misty atmosphere.
• - When using cabtyre cables or lead wire-equipped models outdoors, be sure to take adequate waterproofing measures.

Installation method

• - Use a trunnion mount or clevis mount (parallel only) to mount the main body. Use a U-shaped or I-shaped End fitting to mount the tip.
• - For trunnion mounting, apply grease to the trunnion pin and trunnion hole. Also apply grease to the connecting pin of End fitting and the connecting pin when mounting a clevis.

  Trunnion Mount

  Clevis Mount

• - If the main body vibrates significantly when the cylinder operates, please consider using plain bearings or rolling bearings at the connecting parts. If you require a plain bearing installed in the trunnion hole, please contact us.
• - If the trunnion pin or the connecting pin of the clevis and End fitting faces vertically (when the cylinder is laid on its side) and the main body oscillates, take measures to prevent wear such as inserting plain bearing material into the trunnion hole or the side of the clevis fitting or End fitting.

manual operation

To manually adjust the stroke, release the brake on the brake-equipped motor, then turn the manual shaft on the non-load side of the motor with the manual handle. For instructions on how to release the brake, refer to Instruction Manuals. The manual handle is included with the standard model only.

caveat	If a load is applied to the rod, remove the load before releasing the brake.

Please refer to the product model list (here) for the rod movement amount per rotation of the manual shaft.

Rod rotation prevention

• 1. The rod generates a rotational force (see here) due to the thrust, so it is necessary to prevent rotation. The rod rotational force at the rated thrust is listed in the model list.
Generally, in most cases, rotation can be prevented by attaching the rod end to the driven machine.
• 2. When moving the tip freely or attaching a pulley to pull a rope, etc., it is usually necessary to prevent the rod from rotating. Please select Power Cylinder with the anti-rotation specification (option symbol M).

Lateral load on the rod

If a load is applied perpendicular to the rod (lateral load) or in an eccentric load direction (eccentric load), take the following measures.

About Megger testing

This cylinder is strictly prohibited from Megger testing as it may damage the built-in power module. However, if you wish to perform Megger testing on the external circuit, please remove the brake wiring from the terminal box.

Stroke adjustment external LS (optional) setting

• - An option to attach a limit switch to Power Cylinder body is available, so please use it.
• - Use limit switches to regulate both ends of the stroke.
• ・Please use within the stroke range. If the stroke is exceeded, damage may occur.
• - When adjusting the limit switch, please take into account the coasting distance (here).
• When using at the nominal stroke, set the limit switch so that the cylinder stops within the XA dimension in the dimension table.
• ・When using a slow stop (25 mm/s or less) with an inverter, etc., it may not be possible to set the external LS near the MIN position of the XA dimension of the nominal stroke. If you intend to use it in this way, please contact us.
• - When operating two or more Power Cylinder simultaneously, attach limit switches to each cylinder at the forward and backward limits to stop each cylinder. Avoid controlling all cylinders with one limit switch, as this will cause cumulative stroke errors.
• - The U and H speed Power Cylinder of the G series have a long coasting distance, so there is a possibility that the striker will go over the limit switch.
  (At U speed, the rated hanging load is overcome.) For this reason, be sure to operate the limit signal in the control circuit with self-holding.
• ・Never adjust the C-type thrust detection limit switch yourself, as this may result in a large deviation in the thrust detection setting.

Screw greasing

The screws have been pre-lubricated with grease, so use them as is. Use Tables 1 and 2 as a guide for adding grease. To grease the screws, remove the greasing port bolt on the outer cylinder, advance the rod a full stroke, apply grease to the outer circumference of the screws with a grease gun, and then move it back and forth within the stroke range you will be using. Repeat this action 2-3 times.

caveat	Never insert your fingers into the grease port. If the cylinder is operated with your fingers inside, you may injure your fingers.

Greasing the reducer

Grease is already applied to the tooth surface, so please use it as is.

Initial tooth surface application grease

• Planetary gear section (straight type): Morigiya Grease No. 1 (manufactured by Sumiko Lubricant Co., Ltd.)
• Helical gear part (parallel type): Morigiya Grease No. 1 (manufactured by Sumiko Lubricant Co., Ltd.)

*Basically, grease is not required within the expected travel distance of each size of the G series. Please contact us for more details.
