Tsubaki product selection

Power Cylinder Worm Series

The worm series is an electric cylinder that is ideal for replacing hydraulic cylinders.
The LPWB Worm Series utilizes a high-precision worm gear that utilizes the technology Tsubaki has cultivated over many years, and a highly efficient Ball screw, achieving large thrust.
Allowable thrust: 49 to 490 kN
Nominal speed: 5-72mm/s

Features

·clean

Since there are no hydraulic pumps or piping, there is no need to worry about oil leaks from joints.
Easy to install

No hydraulic pump or piping is required. Just connect a three-phase power supply and it will operate.
・Accurate control possible

Speed changes and accurate positioning are possible using inverters, etc.
・Low cost

The number of parts has been significantly reduced, resulting in cost savings.
・High load capacity

By using a special alloy, it can handle heavy loads just like a jack (maximum load of 50t in the large thrust zone).

- A high-precision worm gear made by Tsubaki is used in the reduction section, and the support structure for Ball screw and gear section is integrated.
- Unlike conventional electric cylinders, the bracket section is not required, so the overall length can be significantly reduced.
- The main body is mounted using clevises on both ends, which is the most popular method for mounting hydraulic cylinders.

Power Cylinder can be operated simply by connecting the power supply

You can try out the thrust calculation online to convert hydraulic cylinder output into approximate Power Cylinder thrust.

- It is now possible to combine clevis fittings and position detection units, which was not possible with conventional Power Cylinder.

*1 If counter LS is installed, it cannot be used in combination with K2, K4, P, or R.
*2 Stroke remains the same.

* Allowable thrust is the maximum load that the cylinder itself can tolerate.
* Rated thrust is the thrust converted from the motor's rated torque.
*If inverter driven, the rated thrust must be confirmed.
*The above specification table shows the generating capacity at a motor time rating of S2: 30 min and Percentage duty cycle of 25% ED.
If the frequency is low, it is possible to reduce the motor size.
*In addition to the specifications listed above, we can also accommodate special combinations.
*The drawing is for reference only. Dimensions may change depending on the detailed specifications.
