When selecting an electric cylinder, you need to comprehensively consider key factors such as load, accu
racy, speed, stroke, environmental adaptability, and control method. The following are key points for spe
cific selection:
1. Load Capacity
Calculating the actual load: This requires including the object's weight, inertia, and friction. For example,
handling equipment requires additional consideration of inertia during acceleration and deceleration.
Allowing for margin: It is recommended that the rated load be 20%-50% higher than the actual maximu
m load to ensure reliability and longevity.
2. Accuracy Requirements
Positioning Accuracy: Precision industries such as semiconductor manufacturing require ±0.01mm, while
general material handling requires ±0.1mm.
Repeatability: Automated assembly and other applications require high repeatability to ensure consistent
movement.
3. Speed
Operating Speed: High-speed sorting equipment requires a speed of at least 1m/s, while slow-speed
adjustment mechanisms require 0.01-0.1m/s.
Speed Control Accuracy: Precise speed control is required for applications such as electronic component
placement. 4. Stroke and Installation
Stroke length: Should be slightly larger than required and fit within installation space limitations.
Mounting method: Options include front and rear flanges, bottom flanges, and more, and should be
customized based on the environment.
5. Environmental Adaptability
Temperature: High-temperature environments require a high-temperature-resistant model; low-tempera
ture environments require a cold-resistant, lubricated design.
Protection Level: Humid/dusty environments require IP65 or higher.
Corrosion Resistance: Stainless steel or special anti-corrosion treatment is required for applications such
as chemical applications.
6. Control and Drive
Control Method: Analog control is suitable for continuous adjustment, such as real-time response to
external signals.
Drive System: Ground-grade ball screws are recommended for higher efficiency and precision. A speed
reducer can be added if necessary.
7. Brand and Model Reference
High-precision brands such as LIGNA and FESTO are suitable for industrial-grade requirements.
Economical Options: Some domestically produced models (such as YHGFEE and OIMG) offer excellent
value for money, but parameter compatibility must be verified.
Note: Before selecting a model, thoroughly communicate your requirements with the supplier to avoid
production delays due to incorrect models.
