Industries across the world are making the switch to electric actuators. With
increasing demands for lower power consumption and higher precision, planetary
roller screw actuators are becoming the next generation of hydraulics and
Roller screws offer a superior alternative in performance compared to hydraulics,
pneumatics, and ball screws in areas such as heavy loads, high speeds, precision,
heat, and noise. Royal Cylinders’ E-Series electric actuators utilize a planetary
roller screw to convert rotational servo-driven motion into linear extension and
retraction of an output rod as the screw rotates. An externally mounted servo motor
supplies the rotational force required to provide the linear action.
Engineered Performance and Durability
Like all Royal products, the E-series cylinder was designed to be the toughest on
the market. All-steel construction, coupled with a precision-made intelligent roller
screw makes the Royal E-series actuator the most durable and advanced on the market.
- Durable all steel construction
- Array of sizing and mounting styles from which to choose
- Engineered with features to combat the toughest industrial settings
- Designed for long life and trouble-free operation in any application
- Royal product support and customer service
The electric series actuators are assembled in heavy wall steel housings able to
withstand the harshest of environments. Standard models are able to push forces of
up to 35,000 lbs.
Chemically inert oil-flow tubing allows users to visually ensure that sufficient oil
is present within the actuator during operation.
The E-Series has various methods of maintaining a clean and contamination-free
internal environment. The gland bushing provides a ridged external wiper to scrape
and free the output rod of outside contaminants as it retracts into the cavity of
the cylinder. Additionally, oil seals in the front and rear of the unit provide the
roller screw an isolated and clean working environment, free of contaminants.
The E-Series offers both induction hardened chrome plated (IHCP) and nitrided output
rods which outperform standard chrome in surface hardness, corrosion and dent
resistance, providing longer seal life.
Units are available with the option of heavy-duty in-line direct motor mounting or
parallel motor mounting, depending on the configuration and application of the
The electric series provides a heavy-duty rugged solution in the smallest housing
while maintaining high-speed capabilities and a long
Planetary roller screws utilize threaded rollers which provide a much larger load
distribution due to having many more contact points between the rollers and the
the screw. This allows for a higher load capacity and a longer life as compared to
acme screw actuators. All load-bearing surfaces are made from hardened steel and are
precision ground to ensure maximum lifetime operation.
