Power Cylinder  U Series

Product photo
  • The smaller, lighter U Series Power Cylinder with more than 6 tons rated thrust.
  • Power cylinder that succeeds in providing a smaller, lighter unit with better cost performance while maintaining the same performance of the previous model (T series).
  • ・Rated Thrust :58.8~490kN
  • ・Nominal Speed :6.5~52mm/s

Features

  • ・Lightweight and compact

    Thanks to newly developed special ball screws and bearings, we succeeded in reducing the total length by a max. of 10% and the mass 35% compared with the previous model (T series). The smaller size and lighter weight makes it easy to replace hydraulic cylinders.

  • ・Complete line-up available

    We added a new model with 50 tons rated thrust, which makes it easy to replace large hydraulic cylinders with a 250 mm inner diameter.

  • ・Improved cost performance

    In addition to achieving cost reductions compared to previous models thanks to smaller and lighter parts, the power cylinder is electrical so it has much better power savings than hydraulic types, greatly reducing power consumption.

Proper use and structure of each type (protective device)

Two types are available, depending on the safety mechanism

  • ・B Type (With wet-type slip clutch)

    A wet slip clutch is built in at the end of the reducer screw shaft.

    The use of a special lining provides protection during overloads.

    By adopting a special lining, it provides a protective function even when the stroke is over.

    Structural drawing

  • ・C Type (With thrust detection mechanism)

    A thrust detection spring unit is built in to the bracket.

    It is effective during push/pull stopping or when electrical signals are required during overloads.

    An electrical signal is output even when an overload acts from the load side during stop or when the stroke is over.

    ※Particularly, the built-in spring bends and absorbs the impact load when it acts impactfully.

    Structural drawing

    ※The 50 ton type with thrust detection unit cannot be regularly used for push/pull stops. Use this type as a safety device.

※This is the operating speed of the cylinder when the motor is operating at tracking speed.

※For strokes with the * mark, the rated thrust is limited.

When replacing the T series,

U Series N type models compatible with the T Series mounting dimensions are available. Since the N type more than triples the expected travel distance of the ball screw over previous models, it contributes to reduced cylinder replacement frequency.

Model No. examples : LPUB6000LN5VT1LPJ-TK

※N:N type (For replacement of the T series) ※Please add "TK" to the end of the model number.

※Applicable models to N specifications are 6000, 8000, 12000, and 16000 sizes.
