Kollmorgen N2 Series electric cylinders replacement and alternative options
Use these supply-network options as a starting point for an engineering check. We can also help source the original Kollmorgen part. Published series figures do not establish an exact-model or drop-in replacement: confirm ratings, fit, interfaces and approvals for your application.
Ball-screw servo electric cylinder in seven frame sizes from 32 to 150, with inline or reverse-parallel motor mounting and optional force sensing, aimed at hydraulic and pneumatic replacement.
Economical stainless-tube electric rod actuator in sizes 10, 15 and 20, aimed at replacing pneumatic cylinders for gating, sorting and diverting; SS1/SS2 options give an all-stainless, IP69K washdown build.
RSA-based rod actuator with integral hardened guide rods, bearings and a tooling plate, so it can carry side and offset loads without external guidance.
Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What a rod actuator is
A rod actuator, sometimes called an electric cylinder, converts motor rotation into linear thrust through a screw and nut inside a tube, pushing a rod in and out like a pneumatic or hydraulic cylinder. The screw is usually a ball screw for efficiency, a roller screw for heavy loads or a lead screw for low cost. The rod is guided by bearings in the tube and an anti-rotation feature, and the motor is mounted inline or folded alongside through a belt or gear stage.
When engineers choose a rod actuator
Choose a rod actuator when the load is guided externally and needs pushing or pulling with controlled force, speed and position, typically to replace a pneumatic or hydraulic cylinder. It brings programmable positions, force control and energy savings. The trade-offs are side load and cost: the rod is not meant to carry significant radial load, and peak force for its size is lower than hydraulics. If the load needs carrying and guiding along the stroke, a rodless actuator or stage is usually better.
How to specify the Kollmorgen N2 Series electric cylinders
Send these with your enquiry and an engineer can confirm the right N2 Series electric cylinders variant or an equivalent:
- Force: peak and continuous or RMS (N)
- Stroke (mm) and retracted length limits
- Speed and acceleration (mm/s, m/s²)
- Duty cycle or full motion profile
- Positioning repeatability (mm)
- Side load and mounting arrangement: trunnion, clevis or flange
- Motor and feedback preference, and environment (IP code, °C)
Common mistakes to avoid
- Sizing on peak force alone instead of RMS force over the cycle
- Rigidly mounting both ends so misalignment puts side load on the rod
- Ignoring critical speed and column buckling on long strokes
- Forgetting that a ball screw back-drives, so vertical loads need a brake

Kollmorgen N2 Series electric cylinders: frequently asked questions
Can you help replace Kollmorgen N2 Series electric cylinders or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including Motion Control Products options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the Kollmorgen N2 Series electric cylinders?
Compact rod-type electric cylinder line that Kollmorgen lists as discontinued. It is made by Regal Rexnord Corporation; Specify Motion can help source it or propose an equivalent.
Who makes the Kollmorgen N2 Series electric cylinders?
The Kollmorgen N2 Series electric cylinders is made by Kollmorgen (Regal Rexnord Corporation) and is listed here for engineers comparing options. Specify Motion is not affiliated with Regal Rexnord Corporation; brand names are used only to identify the product.
Is the Kollmorgen N2 Series electric cylinders still available?
Kollmorgen lists the N2 Series electric cylinders as discontinued. We can help with spares for installed machines, a migration, or an equivalent from our supply network that meets the same published figures.
What is the difference between a rod actuator and a rodless actuator?
A rod actuator pushes and pulls a rod extending from its body, so it suits loads that are guided by the machine, much like a cylinder. A rodless actuator moves a carriage along the body and carries the load itself, which handles moment loads and long strokes within the actuator's own length. Pick rod for thrust and rodless for carrying.
Can an electric rod actuator replace a hydraulic cylinder?
Often, yes, especially where force needs are moderate and precise positioning, cleanliness or energy savings matter. Electric rod actuators with roller screws reach high forces, but extreme forces in a small envelope still favour hydraulics. Compare peak and continuous force, duty, shock loads and space, and check the motor and drive sizing as well as the screw.
