Power Cylinder T Series Multi Type
- Capable of synchronizing multiple cylinders with one motor.
- We offer two options: no overload protection mechanism (LPTB) and with thrust detecting device (LPTC). You can select the one most suited to your application.
- The Multi Series with less than 4 tons rated thrust has changed its name to the T Series Multi Type. There is no change in specifications.
Consider using the U Series Multi Type Power Cylinder for more than 6 tons rated thrust. - Allowable Thrust :4.90~39.2kN
Features
-
・Safe
A thrust detection unit can be built-in to detect overload and protect the machine. (LPTC)
-
・Rugged construction
The actuator area supporting the load and the reducer area are separated. Fluctuating loads will not affect the contact on the gear teeth.
-
・Drive multiple units together
Using an input shaft with enough strength allows synchronous operation of multiple units.
-
・Capable of oscillation
The input shaft and trunnion area have the same shaft center, allowing for swinging motion during interlocked operation.
Proper use and structure of each type (protective device)
-
・B Type (No overload protector )
TB type has no overload protector. We recommend using with Tsubaki's Shock Relay, which can detect electrical overload on the input side.
-
・C Type (Thrust detection limit switch )
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.

- Note 1) Allowable torque for input shaft only. (Check this torque before multi-operation. )
- Note 2) This value includes the idling torque without load.
- Note 3) In the Allowable Max Speed column, TB indicates LPTB type, TC indicates LPTC type.
Special order
An MTO T Series Multi Type Power Cylinder is available with higher-speed operation.
High-speed Operation
- ・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.
- ※For the actuator area, the outer dimension and screw lead differ from standard products. Please contact Tsubaki representative in detais.

Type
B:This is the standard type with no thrust detection mechanism.
C:This unit has a built-in thrust detection mechanism.
Allowable Thrust
This is the rated thrust at which the product can operate.
Relation between Rotation and Stroke
This shows the relation between the rotating direction of the input shaft and the stroke of the cylinder.
Nominal Stroke
This is the stroke distance of the actuator. The manufacturing scope depends on the thrust.
Option symbol
L:This unit comes with two external limit switches for adjusting the stroke.
I:This comes with an I-shaped end fitting.
The I-shaped end fitting is standard for models rated for 58.8 kN {6000 kgf} or more thrust (leave symbol blank).
J:This comes with bellows.
