U Series Multi Type Power Cylinder

The Multi Type Power Cylinder is capable of synchronizing multiple cylinders with one motor.

We have upgraded the Multi Series with more than 6 tons rated thrust as the U Series Multi Type, which provides a broader range of compact designs to our line-up.

Power Cylinder U Series Multi Type

The Multi Series with less than 4 tons rated thrust will become the 「T Series Multi Type.

1. Features of U Series Multi Type

Longer Life

A ball screw with a large load capacity extends its operating life. Compared to previous Multi Series, models with 3x the expected screw travel are also available as MTO products.

High-speed Operation

MTO products can achieve high-speed operation up to 150mm/s.

Safety
A thrust detection unit can be built-in to detect overload and protect the machine. (LPUC)
Tough Construction
The actuator area supporting the load and the reducer area are separated. There is no change in the gear tooth contact due to fluctuating load.
Synchronous Operation
Using an input shaft with enough strength allows synchronous operation of multiple units.
Swinging Operation
The input shaft and trunnion area have the same shaft center, allowing for swinging motion during interlocked operation.

2.Construction and Use for Each Protection Type

A Type without Overload Protector

A Type has no overload protector.

We recommend using with Tsubaki's Shock Relay, which can detect electrical overload on the input side.

A Type
C Type with Thrust Detection Unit

The thrust detection unit combines two types of pressurized disk springs with different spring rates and a limit switch. It operates effectively in the following situations.

  • When performing press/pull stops
  • When electrical signals are required during overload
  • When a lateral overload may be applied during stopping
    *The built-in spring unit can absorb deflection shock load when overload is suddenly applied.
C Type

  • Note 1: Allowable torque for input shaft only. (Check this torque before multi-operation.)
  • Note 2: Values include unloaded idling torque.
  • Note 3: In the Allowable Max Speed column, UA indicates LPUA type, UC indicates LPUC type.
  • Note 4: A long-life option is also available when exceeding standard strokes. Contact a Tsubaki representative for more information.

5.Options

The U Series Multi Type Power Cylinder has two MTO options: higher-speed operation, or longer life.

High-speed operation (*MTO product)
  • Realizes high-speed operation at 150mm/s in all sizes.
  • Allows for high-speed operation of equipment.
  • Air breathers are attached to the actuator area. *You will be required to indicate the location of breathers when ordering.

  • The high-speed LPTC type with thrust detection unit cannot be used as a safety device. Pressing stops are not allowed, so use inverters for a decelerating stop. Contact a Tsubaki representative for more information.
Longer Life (*MTO product)
  • Compared to the previous Multi Series, this series has 3x the expected screw travel and reduces life cycle costs.
  • Allows for long strokes when exceeding standard strokes.

  • For the actuator area, the outer dimension and screw lead differ from standard products. Contact a Tsubaki representative for more information.
