SERAC® is the electric actuator series from Ortlieb and is based on the
proven ASCA® servo spindle technology.
The product line is part of the electric actuator program from Ortlieb.
Through the development of the SERAC® electric cylinders, all the technological advantages of an ASCA® servo spindle can be utilized in a series-produced complete solution.
This makes super compact designs with high power density possible for space-limited applications. Due to the high control quality of the play-free ASCA® servo spindle, applications with very short cycle times can be realized.
Thus, SERAC® electric cylinders offer a clean alternative to hydraulic cylinders for many applications. With the typically slim design of the SERAC® electric cylinders, it is often possible to replace hydraulic cylinders even in existing constructions.
The direct drive of the ASCA® servo spindle (without an additional reduction gearbox) and the smooth movement without rolling back lead to a number of special unique selling points.
Highest power density through small spindle pitches from 0.5 mm
The spindle pitch can be adjusted to the respective application
Direct drive of the ASCA® servo spindle without an additional gearbox, resulting in good controllability and high dynamics.
High durability due to the use of a heavy-duty spindle drive with many power transmission points
Integrated linear displacement measurement system for the highest positioning accuracy under load
Low noise development due to the use of a spindle drive without roller reset.
Interpretation and manufacturing of all PWG components in-house
SERAC® XH Electric Cylinder
The slim design corresponds in many respects to a hydraulic cylinder, so that in many cases a switch to electric drive can be made with little constructive effort.
