  • Power Cylinders

Power Cylinder

Linear actuators (electrical cylinders) are actuators that can be used with simple wiring.

They feature easy handling due to not using hydraulics/pneumatics, and enable high performance/reliable operation through the use of a screw and nut mechanism for the cylinder portion.

There are built-in safety devices for all series for secure operation even when overloaded.

Power Cylinders can solve the problems facing hydraulic cylinders.

Benefits of replacing hydraulic cylinders with power cylinders are…

Tsubaki Power Cylinders are widely used in various industries as they provide easy control and maintenance with a compact design.

Power cylinders do not require the continuous operation of pumps to maintain thrust like hydraulic cylinders do, so they require only 1/5 the power, which can help reduce running costs as well.

Power savings and cost performance approved by LCA

LCA assessment of Power Cylinders

The Power Cylinder has been recognized as a power-saving product by LCA (Life Cycle Assessment). Its power consumption can be significantly reduced compared with air/hydraulic cylinders.

Annual power consumption comparison per unit
Easy installation and maintenance

The electrification allows for simple system structure, which makes installation and maintenance easier. Power Cylinders can be driven just by connecting the cables. No need for the kinds of pipes needed with hydraulic lifters, and there is no risk of the kinds of oil leakage from the unit and pipes.

Simple system structure
Easy control

Power Cylinders can be operated at a stable speed regardless of installation/operation direction. In addition, brake motors allow for energy savings as it is not necessary to supply electricity while retaining the load. Even if there is a blackout or other power outage, there is no danger of falling.
