12000 N High-Performance Linear Actuator for Heavy OEM Motion

Introduction

When an OEM project outgrows light furniture actuators, the next bottleneck is usually force—not electronics. Cellar doors, hatch covers, solar trackers, and agricultural implements need controlled push/pull that stays predictable under shock, weather, and long service intervals. A 12000 N high-performance electric linear actuator fills that gap without adding a separate hydraulic power unit for every axis.

This article introduces Elerover’s heavy-duty SLA-12K family: what the force class means in practice, how stroke options are packaged, how to read the installation drawing, and which applications fit this platform best. Specs below follow published product data—share your duty cycle if you need engineering confirmation for a hinged or continuous load.

Why 12000 N Matters for OEM Design

• Industrial force class — up to about 12000 N / 1200 kg / 2700 lbs at the slowest published speed option
• 12 V / 24 V DC — fits common vehicle, marine, and industrial control architectures
• Stroke ladder — standard lengths from short cellar-door packages through longer hatch and tracker strokes
• Clevis mounting — Φ13 mm eyes front and rear for pin-joint installation
• Built-in limit switches — automatic stop at full extend and retract
• IP66 sealing — dust-tight housing with water-jet protection for outdoor-adjacent duty
• Optional feedback — Hall or potentiometer packages for synchronized or position-aware control
• Manual override — emergency motion when power is unavailable

These traits make the platform a practical step-up from mid-force actuators when packaging still needs an electric drive instead of a full hydraulic circuit.

Stroke Range at a Glance

The family shares one mechanical architecture and scales primarily by stroke. That keeps mounting interfaces consistent while letting purchasing stock the travel length each machine needs.

Typical stroke options span roughly 50 mm to 700 mm, with custom lengths available for OEM programs. Longer strokes still use the same clevis pattern and outer-tube envelope, which simplifies CAD libraries and spare-part planning.

When you select stroke, also check:

1. Travel time — faster gearings reduce max thrust
2. Hinged loads — cellar doors and hatches often need 2–5× the lid weight at the actuator
3. Duty cycle — continuous full-load running is not recommended; plan for intermittent service

Installation Dimensions

Key published envelope numbers for mechanical layout:

Dimension	Value
Retracted center-to-center length	Lmin = 190 mm + stroke
Housing length (gear / motor section)	about 228.5 mm
Overall height	150 mm
Overall width	about 78.2 mm
Outer tube diameter	about Φ28.5 mm
Mounting hole	Φ13 mm (front and rear clevis)
Clevis body diameter	about Φ28 mm
Cable length	1000 mm typical
Rear clevis orientation	0° / 30° / 60° / 90° options

Example: a 50 mm stroke package retracts to about 240 mm center-to-center and extends to about 290 mm. Keep cable routing clear of the moving tube and confirm rear clevis angle before welding brackets.

Speed Versus Load

Different internal ratios trade thrust for speed. Use the published ladder as a selection starting point (values are approximate maximums for vertical push under intermittent duty):

No-load speed	Full-load speed (approx.)	Max thrust	Self-lock (approx.)
6 mm/s	5 mm/s	12000 N	15000 N
8 mm/s	6 mm/s	11000 N	12000 N
12 mm/s	9 mm/s	10000 N	12000 N
16 mm/s	10 mm/s	7000 N	8000 N
20 mm/s	11 mm/s	6500 N	8000 N
25 mm/s	14 mm/s	5000 N	6000 N
38 mm/s	24 mm/s	3200 N	4000 N
60 mm/s	30 mm/s	2000 N	3000 N

Working speed falls as load rises. Prefer sizing so normal duty sits below the absolute maximum thrust—service life usually improves when the actuator is not held at peak load for the entire stroke.

Typical Applications

• Cellar doors, trapdoors, and hatchways
• Solar tracking and outdoor positioning frames
• Agricultural machinery and dump / lift implements
• Marine hatches and deck equipment
• Elevator platforms and industrial lifting tables
• Construction gates and heavy access panels

If your load is hinged, measure geometry early. A lid that “only weighs 200 kg” can still demand several thousand newtons at the actuator depending on lever arm and opening angle.

How to Specify an OEM Package

Send the following with your RFQ so engineering can map a published configuration:

1. Required push/pull force (or lid mass + hinge geometry)
2. Useful stroke and preferred travel time
3. Supply voltage and controller type
4. IP / wash-down expectations
5. Need for Hall or potentiometer feedback
6. Annual quantity and sample timing

Elerover can align stroke, voltage, feedback, cable length, and connectors to your enclosure.

Closing

A 12000 N electric linear actuator is not a furniture micro-drive scaled up—it is a different force class with its own mounting math, current draw, and duty limits. The SLA-12K family gives OEM teams a clear envelope (Lmin = 190 + stroke), IP66 sealing, clevis interfaces, and a published speed/load ladder so mechanical and electrical design can move together.
