Tolomatic Electric Rod-Style Linear Actuators
Controlled linear motion for pressing, lifting, positioning, and pneumatic or hydraulic cylinder replacement.
Scott Equipment Company helps manufacturers in North and South Carolina review Tolomatic electric rod-style actuator applications, compare motion technologies, and support the related components needed to turn an actuator selection into a working machine solution.
Start With the Cylinder Application
Review the load, force, stroke, speed, environment, and control requirements before selecting the rod-style actuator family.
What Is an Electric Rod-Style Linear Actuator?
An electric rod-style linear actuator creates straight-line motion in a package that looks similar to a traditional cylinder. Instead of using air or hydraulic fluid, it uses an electric motor and screw-driven mechanism to extend and retract the rod.
This makes rod-style electric actuators useful when a machine needs controlled pushing, pulling, lifting, pressing, clamping, positioning, or cylinder replacement. For the full Tolomatic product overview, visit Scott Equipment’s Tolomatic actuators and motion control solutions page.
Scott Equipment’s Role
Scott Equipment Company helps customers review the actuator application before the product family is selected.
Our team can help gather force, stroke, speed, duty cycle, environment, motor, drive, and installation details so the actuator is matched to the machine rather than selected by size alone.
Better Position Control
Electric actuators can support controlled positions, speeds, acceleration, deceleration, and force profiles when the machine needs more than simple extend-and-retract motion.
Cleaner Operation
Electric motion removes hydraulic fluid from the axis and reduces the need for compressed air at the point of motion.
Repeatable Motion
Servo or stepper-controlled electric actuators can help improve repeatability, feedback, and process consistency.
Cylinder Replacement
Rod-style electric actuators are often reviewed when a customer wants to replace a pneumatic or hydraulic cylinder with a more controlled electric axis.
Start With the Motion Requirement
A rod-style actuator may look similar to a cylinder, but proper selection depends on the complete motion profile, not just bore, stroke, or mounting dimensions.
How Tolomatic Electric Rod-Style Actuators Work
Tolomatic electric rod-style actuators use screw-driven technology to convert rotary motor motion into linear rod movement. The screw type has a major impact on actuator performance, efficiency, force capacity, speed, cost, and expected life.
Choosing the right screw technology starts with the application. A high-speed positioning axis, a high-force press, and a low-speed adjustment mechanism may all need different actuator designs.
Scott Equipment’s Role
Scott Equipment Company can help review whether the application is better suited for a ball screw, roller screw, or more economical nut design.
The review should include force, speed, duty cycle, life, environment, and how the actuator will be mounted and controlled.
Ball Screws
Ball screws are designed for efficient, low-friction motion. They provide smooth and precise movement for applications that need repeatable positioning and good speed.
They are often used for packaging, positioning, light pressing, material handling, and machine adjustment.
Roller Screws
Roller screws are built for high-force, long-life, and higher-duty applications. More contact points help distribute load and support demanding motion profiles.
They are often reviewed for pressing, forming, hydraulic replacement, and high-force positioning.
Acme, Bronze, or Solid Nut Designs
Some rod-style electric actuators use acme, bronze nut, or solid nut designs for simpler motion requirements.
These can be useful for lower-speed, moderate-force, shorter-duty, or cost-sensitive applications.
Rod-Style Actuator Options for Different Machine Needs
Tolomatic offers multiple electric rod-style actuator families. Each product family supports a different range of force, speed, environment, motor compatibility, and machine design needs.
Scott Equipment Company can help determine which family should be reviewed based on the operating conditions and the larger machine objective.
Application Before Part Number
Rod-style actuators may be used for simple replacement work, but many projects require deeper review.
The best family depends on force, cycle rate, environment, controls, motor selection, and whether the goal is a pneumatic replacement, hydraulic replacement, or new machine design.
RSA Series
The RSA Series is a flexible electric rod actuator family for accurate, high-force motion in general industrial automation.
It may be considered for motion control, valve actuation, pressing, injection molding, and pneumatic or hydraulic replacement applications.
RSX Series
The RSX Series is built for extreme-force electric actuation and hydraulic-class applications.
It may be reviewed for high-force pressing, forming, heavy-duty positioning, and applications where a hydraulic cylinder is creating maintenance or control concerns.
RSH Series
The RSH Series is a hygienic electric rod-style actuator family for food, beverage, and sanitary washdown applications.

Do Not Select the Family by Force Alone
Force is important, but actuator selection also depends on speed, stroke, side loading, environment, motor compatibility, feedback, duty cycle, and required service life.
Where Electric Rod-Style Actuators Fit
Tolomatic electric rod-style actuators can be used across many machine types. The strongest fit is often found where the application needs force, repeatability, controlled motion, cleaner operation, or better feedback.
Scott Equipment Company supports these applications for maintenance teams, plant engineers, OEMs, machine builders, and integrators throughout the Carolinas.

When Electric Rod-Style Actuators Make Sense
Electric, pneumatic, and hydraulic actuators each have a place in industrial automation. The goal is not to replace every cylinder with an electric actuator. The goal is to select the technology that best fits the motion requirement.
Electric rod-style actuators are often reviewed when customers need more control, cleaner operation, better feedback, or reduced fluid-power maintenance.
Conversion Support
Scott Equipment Company can help review whether an electric actuator is a practical replacement for an existing pneumatic or hydraulic cylinder.
For deeper information, visit our hydraulic to electric actuator conversion page.
Electric Rod-Style Actuators
Best when the application needs controlled motion, multiple positions, clean operation, feedback, or reduced fluid-power maintenance.
Common examples include positioning, pressing, filling, machine adjustment, test stands, and washdown automation.
Hydraulic Cylinders
Best when very high force or power density is the top requirement and the hydraulic system is already performing well.
They also require attention to power units, fluid maintenance, hoses, seals, leaks, and heat.
Pneumatic Cylinders
Best for simple, fast, and cost-effective extend-and-retract motion.
They may be less ideal when the application needs multiple positions, detailed motion profiles, or reduced compressed air demand.
The Right Technology Depends on the Application
Electric actuation can solve many control, maintenance, and cleanliness problems, but pneumatics and hydraulics still make sense in the right applications. Scott Equipment Company can help compare the options before the machine is changed.
