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.
• - 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 to install the main body. Attach the tip with a U-shaped or I-shaped End fitting.
• - 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.
• - If the main body vibrates significantly when the cylinder is activated, 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.

Figure 1 Installation method

*For mounting hardware, please refer to the options section.

manual operation

To adjust the stroke manually, release the brake on the brake-equipped motor, then turn the manual handle shaft of the reduction section with an adjustable wrench or socket wrench.

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

Please refer to the standard model list (here) for the rod travel distance per rotation of the manual shaft.

Rod rotation prevention

• 1. The rod generates a rotational force (see here) as a result of the thrust, so it is necessary to prevent rotation. The rod rotational force at rated thrust is listed in the model list. In most cases, it is possible to prevent rotation by attaching the end of the rod to the driven machine.
• 2. When moving the tip freely or when attaching a pulley to pull a rope, etc., it is usually necessary to prevent the rod from rotating. If you require Power Cylinder with a rotation stopper, please contact us. Note that the LS rod of the external limit switch unit cannot be used to prevent rotation.

Lateral load on the rod

Install the rod so that no bending load (lateral load) is applied to it.

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 100% nominal stroke, set the limit switch so that the cylinder stops within the XA dimension in the dimension table.
• - When operating two or more Power Cylinder at the same time, install limit switches at the upper and lower limits of each cylinder.
• ・Never adjust the C-type thrust detection limit switch yourself, as this may result in a large difference in the thrust detection setting value.
• ・The high-speed type (H speed) of Power Cylinder T series has a long coasting distance, so there is a possibility that the striker will go over the limit switch. For this reason, be sure to operate the limit signal in the control circuit with self-holding.
• Stroke-adjustable external LS (optional) mounted vertically (stroke 300 mm or less)...The connector of the external LS protrudes below the trunnion mounting base surface (Fig. 5).

Ball screw lubrication

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

The gears and bearings in the reduction section are pre-lubricated with grease and are therefore not required to be lubricated.

Initial grease application to reducer

• Gear case: Daphne Eponex SR No.1
• Planetary reduction part: Moly gear grease No.1
