Key takeaways for OEMs from the electric vs. hydraulic discussion
Recent industry discussions around linear motion actuators and mobile machinery share several common conclusions:
- Electric cylinders excel where precision, cleanliness, and energy efficiency matter
- Hydraulics remain unmatched in high-force, shock-loaded environments
- The real gains come from choosing the right technology for each function — not forcing one solution everywhere
In other words, the question OEMs are asking in 2026 is no longer
“Which technology wins?” It’s
“Which technology solves the specific problem best?”
Proven benefits of electric cylinders — Beyond the hype
Electric cylinders (electromechanical actuators) deliver measurable, proven advantages when applied correctly:
- Energy efficiency on demand
Power is consumed only during movement — no constant energy losses from pumps running idle. Typical system efficiency reaches 70–80%.
- High motion accuracy and repeatability
Absolute position sensing enables precise control of position, speed, and force.
- Clean and safe operation
No hydraulic oil, hoses, or leakage risk — critical in food handling, marine, and environmentally sensitive applications.
- Lower lifetime maintenance
No oil changes, fewer wear components, and integrated diagnostics enable predictive maintenance.
These are not theoretical benefits. They are already delivering value in demanding real-world applications.
Where electric cylinders have replaced traditional hydraulics — In practice
Across multiple industries, Norrhydro has successfully replaced conventional hydraulics with an electromechanical motion solution. Just a few examples from our customer cases:
1. Marine & Offshore Deck Equipment
In a marine deck application, the customer aimed to remove hydraulic lines entirely from deck machinery.
The solution:
- Push/pull functions replaced with electromechanical actuators
- Integrated control system with braking, end cushioning, and safety logic
The results:
- Elimination of pressurised oil hoses and pipes
- Reduced risk of oil leakage
- Improved uptime and safer deck operations
- More compact and lighter system than traditional hydraulics
2. Wood Processing
In a wood processing environment, customers sought a
cleaner, more energy-efficient alternative for core machine movements.
The solution:
- Hydraulic systems replaced with high-force electric cylinders
- Precise motion control integrated into the machine’s automation
The results:
- Significantly improved energy efficiency
- Better control accuracy and end damping
- Increased operational safety and longer system lifetime
3. Cold Logistics & Food Transportation
In cold container logistics, the key challenge was
eliminating contamination risk while improving space efficiency.
The solution:
- Electric actuators installed on pallet handling platforms
- Removal of hydraulic pipes and hoses inside containers
The results:
- Zero oil leakage risk
- Precise pallet positioning for improved space utilisation
- Cleaner, maintenance-free operation in temperature-controlled environments
It isn’t all about replacing hydraulics everywhere
When examining real use cases alongside industry discussions, a more pragmatic view becomes clear:
The future is not fully electric or fully hydraulic. It’s intelligently combined.
High-force, high-impact functions may still rely on hydraulics. Precision, energy-sensitive, or cleanliness-critical movements increasingly favor electric cylinders. The winning strategy is
engineering-driven selection, not ideology.
Moving beyond the polarisation
Instead of choosing sides, OEMs need motion solutions that fit their machines, duty cycles, and sustainability goals. This is where modern motion control development is heading:
- Application-specific actuator choice
- Full system design (mechanics, electrics, control, and software)
- Scalability across mobile and industrial machinery
When electric cylinders are used where they deliver real value — and hydraulics where they make sense — OEMs achieve:
- Lower total cost of ownership
- Improved energy efficiency
- Compliance with tightening environmental requirements
- Better machine performance
