SERAC® Electric Cylinder
From Joy in flexibility.
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.
Functionality and design of spindle drives:
A spindle drive converts rotary motion into linear motion.
It consists of a precision-manufactured spindle, a nut unit, and a matching guide.
Ortlieb relies on finely tuned spindle technologies that are designed for minimal wear and high efficiency.
Different spindle systems are used depending on the application:
Trapezoidal thread spindles
Ball screw spindles
Planetary roller spindles (PWG)
Special spindles for high loads or high dynamics
By selecting the appropriate spindle technology, the drive can be optimally adapted to force, speed, stroke, and precision.
What system advantages do the SERAC® drives offer?
Compact design with integrated guide system

Combination with planetary roller screws and electric cylinders
In many applications, screw drives form the basis for complete linear systems.
Ortlieb often combines its spindle drives with:
Planetary roller screws (PWG) for compact, backlash-free high-performance drives
Ortlieb servo spindles for particularly dynamic linear axes
SERAC® electric cylinders as an electrical alternative to hydraulic systems
These modular solutions enable precise, energy-efficient linear movements for a wide range of requirements.
