Mounting Direction

Any of horizontal, vertical and inclined direction is allowed.

Installation environment

• ・All models are totally enclosed structures so that they can be used normally outdoors, however, under adverse conditions exposed to constant water and steam etc., and snow accumulation, although they are an outdoors type, an appropriate cover is required. The power cylinder can generally be used in a range of -15℃ to 40℃, although it varies depending on the use conditions. When using at 40℃ or higher, always protect with a heat insulating cover, etc. Never use in flammable environments. There is a risk of explosions and fire hazards. Do not use in areas subject to vibration or shock of 1 G or more.
• ・When using a cylinder of the cabtire cable lead wire specification outdoors, carry out waterproofing treatment sufficiently.

Mounting

• ・For installation of the power cylinder, use a trunnion mount or clevis mount. Install the tip with an I-shaped end fitting.
• ・Apply grease to the trunnion pin and the trunnion hole for trunnion mounting. Also, apply grease to the connecting pin of the end fitting and the connecting pin for clevis mounting.
• ・When the main body greatly swings by operation of the cylinder, consider using a sliding bearing or a rolling bearing for the connecting part.
  Cylinders whose trunnion hole is provided with sliding bearing are available upon request.
• ・When the trunnion pin or connecting pin for the clevis or the end fitting is directed in the vertical direction (when the cylinder is installed horizontally), and the main body swings, take countermeasures for wear such as inserting a bearing member into the trunnion hole, the clevis fitting, or the side part of the end fitting.

Manual operation

When manually adjusting the stroke, rotate the manual handle shaft on the reducer part with a wrench after releasing the brake.

For the rod stroke per one turn of the manual shaft, refer to the standard model list (click here).

Prevention of rod rotation

• 1.Prevention of rod rotation is required as the rod generates the rotational force along with the thrust. The rod rotational force at rated thrust is shown in the standard model list. Generally, rotation can be mostly prevented by installing the rod end to a driven machine.
• 2.When operating with the end set free or in the case of application to install pulleys to pull a rope, a rod anti-rotation is normally required. If you require an anti-rotation version of the power cylinder, please contact us. Note that the LS rod of the external limit switch unit cannot be used to prevent rotation.

Lateral load on rod

Install the power cylinder so as to prevent bending load (lateral load) from acting on the rod.

When the radial load work on the cylinder or unbalanced load on the rod, take the following countermeasures.

(1)Side load …Install guide roller etc., on the rod part. (Fig. 2)

Fig. 2 Side load

Install a guide roller and avoid directly a lateral load on rods.

(2)Unbalanced load …Install balance weight etc. (Fig. 3)

Fig. 3 Unbalanced load

There is when an unbalanced load, install a counter weight etc.

※A guide is required in this layout.

Megger testing

Megger testing is prohibited for this cylinder. It may break the built-in power module. Remove the brake wiring for the terminal block when conducting megger testing of the external circuits.

Setting of stroke adjusting external LS

• ・A type of option which allows the limit switch to be mounted on the power cylinder body, which can be selected.
• ・Regulate the both ends of the stroke by the limit switch.
• ・Use within the stroke range. If the stroke is exceeded, breakage may occur.
• ・Take a coasting amount (click here) into consideration for adjustment of the limit switch.
• ・When using the cylinder at the nominal stroke 100%, set the limit switch so that the cylinder stops within the XA dimension in the Dimensions Table.
• ・As a high-speed type (H speed) has a long coasting distance, the striker may override the limit switch. For this reason, make sure to allow a limit signal to be self-held on the control circuit.
• ・Be sure to wire the limit switch for thrust detection of the C type before use. Operating without wiring may cause damage.
• ・Adjustment of the limit switch for thrust detection of the C type must not be carried out by the customer. The preset value of thrust detection may change greatly.

Lubrication on ball screw

Use the ball screw as it is because it has been lubricated with grease in advance. Refill grease with reference to Table 1 and 2 as a guide. To apply grease to the ball screw, remove the greasing port bolt on the outer and extend the rod in the full stroke and apply grease to the outer circumference of the ball screw with a grease gun, and then retract the rod within the stroke to be used. Repeat this operation a few times.

Table 1 Exclusive grease

※Grease dedicated to the power cylinder U series. Avoid greasing with other greases.

Greasing on Reduction part

For the gear and the bearing in the reducer part, the gear case is filled with grease. It is not necessary to grease refill.

Initial grease filled in reduction part

• Gear case ：DAPHNE EPONEX SR No.1
• Planetary gear ：Moly gear grease No. 1
