SERAC® Electric Cylinder
From Joy in flexibility.
Electric cylinders are the modern solution for precise, low-maintenance, and powerful linear movements. With the SERAC® electric cylinder series, Ortlieb offers a particularly compact and highly functional line of electric drives for industrial applications. They combine mechanical robustness with intelligent sensors, enabling high-dynamic positioning in various industries.
This makes super compact designs with high power density possible for space-limited applications. Due to the high control quality of the play-free Ortlieb 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 Ortlieb servo spindle (without an additional reduction gearbox) and the smooth movement without rolling back lead to a number of special unique selling points.
What distinguishes a high-quality electric cylinder?
An electric cylinder converts rotary motor movements into precise, linear movements. Compared to pneumatic or hydraulic systems, an electric cylinder offers:
Significantly higher energy efficiency
Precise and repeatable positioning
Lower maintenance costs
clean operation without leakage
flexible controllability via common industrial drives
Ortlieb electric cylinders are based on the Ortlieb servo spindle and thus offer exceptional power density in a compact design. They are ideal for demanding applications in mechanical engineering, automation, and test and measurement technology.

Welche Vorteile bieten Elektrozylinder gegenüber Hydraulikzylindern?
Elektrozylinder arbeiten energieeffizienter, sind präziser steuerbar und benötigen keine Hydraulikflüssigkeit. Sie ermöglichen sauberen, wartungsarmen Betrieb und eignen sich ideal für automatisierte Anlagen.
Welche Ansteuerungsmöglichkeiten gibt es?
SERAC®-Zylinder können direkt oder über Fremdmotoren angesteuert werden. Sie sind kompatibel mit marktüblichen Steuerungen (z. B. SPS, Motion Controller).
Gibt es unterschiedliche Baugrößen?
Ja, SERAC® ist in mehreren Baugrößen und mit verschiedenen Spindelsteigungen verfügbar – angepasst an Kraft, Geschwindigkeit und Einbauraum.
Welche Lebensdauer haben Elektrozylinder?
Je nach Anwendung und Lastprofil erreichen Elektrozylinder von Ortlieb mehrere Millionen Zyklen ohne Wartung.
