250 Series Electric Cylinder (250mm Bore) — Heavy-Duty Linear Motion, Direct from the Source Factory
Introduction
When industrial automation demands more force, more speed, and more precision, standard electric cylinders simply fall short. Our 250 Series Electric Cylinder — featuring a 250mm cylinder bore — is engineered specifically for the most demanding linear motion applications, delivering exceptional load capacity, rapid response, and micron-level positioning accuracy in a single, robust package.
As a direct source manufacturer, we eliminate middlemen, reduce lead times, and pass the cost savings directly to our customers. Every electric actuator cylinder we produce is built in-house, from raw material machining to final assembly and testing.
As Jimmy Actuators is a leading manufacturer of solar tracking actuators, our electric cylinders heavy duty are ideal to use for all solar trackers and industrial. The durable construction and convenient prices makes them best for boosting the operational value of numerous solar devices.

High Load Capacity for Heavy-Duty Applications
The 250mm bore of our 250 Series electric cylinder is the foundation of its outstanding force capability. With this large-diameter piston design, the cylinder can generate thrust forces far beyond what smaller standard units offer, making it the ideal electric lift cylinder for applications such as:
- Heavy material lifting and positioning systems
- Pressing, clamping, and forming equipment
- Industrial automation production lines
- Steel, shipbuilding, and heavy machinery industries
- Large-scale test benches and load simulation systems
Depending on the selected screw lead and motor configuration, the 250 Series can handle loads from several tons up to extreme heavy-duty ratings, providing a clean, energy-efficient hydraulic-free alternative to traditional hydraulic cylinders.
High Speed and Rapid Response
Speed matters in modern production. Our 250 Series electric actuator cylinder is designed with optimized ball screw or roller screw drive systems and high-torque servo motors to achieve fast extension and retraction speeds without sacrificing control. Unlike hydraulic systems that require warm-up and suffer from fluid compressibility delays, our electric cylinders respond instantly to control signals, enabling shorter cycle times and higher throughput for your equipment.
High Precision Positioning
Precision is where our 250 Series truly excels. Integrated with high-resolution encoders and closed-loop servo control, this electric lift cylinder delivers repeatable positioning accuracy in the micron range. Multi-point positioning, synchronized multi-axis motion, and programmable stroke control are all easily achieved — capabilities that hydraulic or pneumatic cylinders simply cannot match. Whether your application requires gentle contact force control or exact stroke positioning, the 250 Series provides stable, consistent performance shift after shift.
High Quality You Can Trust
Quality is not a feature — it is our standard. Every 250 Series electric actuator cylinder is manufactured under strict ISO quality management systems. Key components including the cylinder barrel, piston rod, bearings, and screw drive are precision-machined and rigorously inspected. Each unit undergoes comprehensive factory testing for load capacity, speed, accuracy, sealing performance, and endurance before shipment. Our cylinders feature:
- High-strength alloy steel construction with hard chrome-plated piston rods
- Premium sealing systems for long service life and low maintenance
- IP-rated protection options for harsh environments
- CE-compliant electrical components and safety features
Because we are the source factory, we control every step of production — no outsourced assembly, no compromise on materials.
Direct Source Factory Advantages
Buying directly from the manufacturer means real value: competitive factory pricing, guaranteed genuine components, fast delivery, flexible customization (stroke length, mounting style, motor type, feedback options), and professional technical support from engineers who actually build the product. We welcome OEM/ODM partnerships and can tailor the 250 Series electric lift cylinder to your exact application requirements.
Conclusion
If you are looking for a electric actuator cylinder that combines massive load capacity, high operating speed, precision positioning, and proven reliability — all backed by a direct manufacturer — the 250 Series (250mm bore) is your solution.
