Technical Data 　Linear actuator 　Power Cylinder 　Installation / maintenance

Cautions for installation ：F Series

  • ・Use pins to connect the power cylinder with the equipment. Align phases of pins (clevis fitting pin and end fitting pin).
  • ・Apply grease into the clevis fitting holes and end fitting holes, and pins before installation.
  • ・Pay attention so as not to apply a lateral load on the power cylinder when installing.
  • ・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 -5℃ 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. In addition, avoid using it in a location where vibration or shock exceeding 1G is applied.
  • ・The main body is of outdoor specifications however, carry out proper waterproofing treatment on the motor lead wire terminal with waterproofing connectors etc.

Cautions for use ：F Series

  • ・Speed and current value change with an increase/decrease in load. For details, refer to the characteristics diagram. Linkage operation cannot be performed due to characteristics of the motor.
  • ・When rectifying alternating current to use without using battery power, make sure to smoothen the current and provide a DC power supply with a capacity so that the voltage does not drop. It greatly affects performance of the power cylinder and the duration of the life of the brush.
  • ・12V DC specifications are within a voltage range from 10 to 14V, and 24V DC specifications are within a voltage range from 20 to 28V. Note that the speed varies if the voltage varies due to the characteristics of the DC motor.
  • ・No overload detection mechanism is built in the LPF series. When detecting an overload, commonly use the overload detection unit as an option. For LPF010 to 040, combine with the overload detection unit to allow for press stopping. (For LPF100 to 600, an overload detection unit of special model can be manufactured, however, press stopping cannot be performed. ) When press stopping is performed, allow the equipment to have a sufficient strength (rated thrust x 300%). When not using the overload detection unit, never perform press stopping, and use within the stroke range otherwise the power cylinder may be damaged.
  • ・A model of stroke 50mm cannot be equipped with a stroke adjustment external LS (optional item). The mechanical stroke adjusting range of the stroke adjustment external LS (optional item) is 60mm or more. However, note that it does not include a coasting distance.
  • ・Anti-rotation is required because the rod of the power cylinder generates a rotating force with thrust. The rotating force of the rod is as follows.
    Model LPF010H LPF020M LPF040L LPF100H LPF200M LPF300L LPF600L
    Rod turning force
    N・m{kgf・m}    		 0.14{0.014} 0.28{0.029} 0.55{0.056} 1.75{0.179} 3.50{0.357} 5.25{0.536} 5.81{0.593}
  • ・The position adjustment of the limit switch should be set into consideration the amount of coasting of the cylinder.

    Reference value for coasting distance

    Units ：mm
    Model No. Coasting distance when lifting Coasting distance when lowering
    LPF010H 4 7
    LPF020M 2 4
    LPF040L 1 3
  • ・If you want to reduce the amount of coasting of the cylinder, we recommend a circuit that applies dynamic brakes.
    Dynamic braking reduces the amount of coasting to approximately 1 mm. (All models )
  • ・For short strokes, use the LS cam in a dynamic circuit, as it may overcome the microswitch.

Cautions for maintenance and inspection (F Series )

  • ・The operating portion and reduction portion are filled with grease, therefore, it is not necessary for them to be greased.
  • ・The duration of life is 15000 reciprocations as a guide.
  • ・Structurally, repairs and parts supply are not available. If the above reference life is exceeded, replace the main body with a new one.
