Elektro ISO15552 electric cylinder
ELEKTRO series cylinders are electrically controlled actuators with an ISO 15552 interface.
ELEKTRO series cylinders are electrically controlled actuators with an ISO 15552 interface.
The range comprises cylinders with 32, 50 and 63 mm bores, strokes up to 1500 mm, axial thrust up to 6500 N and speed up 2000 mm/s.
The piston rod is extended by means of a tempered screw and a ball nut. The piston has a guide ring calibrated to minimise the play between it and the liner and hence vibration during ball screw rotation. The cylinder can be fitted with a built-in anti-rotation system with two opposing shoes running in separate longitudinal slots in the liner. The piston is equipped with a magnet and the liner has longitudinal slots to accommodate sensors. The piston rod has an increased outside diameter and thickness to achieve maximum rigidity
and be able to resist radial and peak loads better.
A system for greasing the screw/screw nut is incorporated. The cylinder can be fixed using numerous standard accessories for pneumatic cylinders, including an intermediate hinge.
The motor can be chosen from a wide range of STEPPING motors and BRUSHLESS motors. One version is for in-line installation, where the drive shaft is connected directly to the
screw by means of a joint. Another version has a geared motor, where movement is transmitted by means of pulleys and a cog belt with a 1:1 gear ratio. Suitable motor drives
are also provided. Adapted flanges and joints can be built if the customer prefers to use motors of another make.
Since these products are relatively new on the market, potential users often ask various questions. The main ones are listed below, together with a short answer. If you require
further details, please refer to the technical documentation and/or consult one of our specialists.
When can an electric cylinder be used?
There are endless possible applications. For simplicity, the list below gives the most frequent ones.
| SLOW | High loads, moved smoothly, without impact or jerks. | |
| FAST | Fast movements, controlling acceleration and braking ramps, avoiding end-of-stroke impact. | |
| NO OIL | Replaces hydraulic units and cylinders when you wish to avoid problems associated with fluid leakage or flammability. | |
| NO AIR | When there is no compressed air supply and you do not want to use a compressor. | |
| SYNCHRO | When you need two or more synchronised movements. For example for raising tables or in self-centring systems where workpieces are gripped. Two or more electric cylinders with synchronised actuators are used. | |
| MULTIPOSITIONING | When you need to stop movement at any point of the stroke. | |
| REPROGRAMMING | When you want to vary the work cycle by changing strokes, speeds or forces. | |
| PUSH | When you want to apply a known and variable force for pressing, moving or similar operations, e.g. to press one item into another without impact or recoil. | |
| MEASURING | Useful when you want to know the position reached after a certain movement. Can be used indirectly for measuring the dimensions of an object. | |
| ENERGY-SAVING | An electric cylinder uses much less electricity than a pneumatic cylinder. In applications with frequent cycles and long strokes, the amount of electricity saved easily offsets the higher initial outlay. |
