A flexible and entirely maintenance-free range of electric cylinders has been introduced to the African market by leading drive specialist SEW-Eurodrive, following overwhelming success of the product in the European market.
By incorporating its proven gear motor oil bath lubrication system into its electric cylinder offering, SEW-Eurodrive’s new CMS63S range features a number of special properties, such as a very high thermal power density, increased efficiency and zero maintenance throughout the entire service life. In standard electric cylinders, screw drives are usually lubricated with grease.

SEW-Eurodrive’s mechatronic application engineer, Paul Strzalkowski, states that this always results in a minor loss of lubricant, with regular re-lubrication becoming a necessity. “The oil bath, located in the linear unit, is closed off externally by means of two sealing systems. By using robust seals used in hydraulics, there is no need for seals on the individual internal components,” he says.
Strzalkowski notes that the oil bath has a positive effect on the service life of the spindle nut, bearings and guides. “There is less friction, which results in less heat being generated in the components. What’s more, the lubricant transfers any heat from the components inside the motor to the housing surface.”
The CMS63S linear unit also features a servo drive motor, with parts of the linear unit integrated into the rotor of the motor. This creates the compact design that marks a departure from conventional solutions in which the linear unit is connected to the motor via an adapter and coupling.
When combined with the skin-hardened, chrome-plated piston rod – which also has an integrated anti-twist element (torque arm) – the electric cylinder displays the same qualities as tried-and-tested hydraulic cylinders. The piston rod seal is permanently leak-free, thereby ensuring that the drive is particularly suitable for meeting more stringent requirements in terms of hygiene, protection from moisture and dust, and in harsh operating conditions.
CMS63S electric cylinders are suitable for a wide range of applications, ranging from the food and beverage to automotive industries, thanks to the compact design of the self-contained drive system. “When combined with electronic servo drive technology, highly dynamic and precise motion sequences are possible,” concludes Strzalkowski.
