⚙️ Core Features & Technical Highlights

**High-Speed Response & Smooth Operation**

Utilizing a high-performance servo motor and a synchronous belt drive system, the unit achieves a maximu

m linear speed of 1.5–2.0 m/s. Its exceptional acceleration capabilities make it ideal for meeting the deman

ds of high-frequency reciprocating operations.

**Semi-Sealed Structure: Dust & Splash Resistant**

The module features a semi-sealed protective cover design that effectively blocks metal debris, dust, and 

minor liquid splashes. This makes it suitable for use in mildly contaminated environments, thereby extendi

ng the service life of internal components.

**High-Precision Positioning: Repeatability of ±0.05 mm**

Equipped with a high-resolution encoder and precision linear guides, the system ensures precise and stable

 motion control—making it perfectly suited for automated processes with strict positioning requirements.

**Modular Design & Flexible Installation**

Supports multi-axis combinations (e.g., X+Y, X+Z) as well as horizontal or vertical mounting configurations. 

Its standardized interfaces facilitate seamless integration into various automated production lines, thereby 

shortening equipment development cycles.

**Customizable Long-Stroke Capabilities**

Standard stroke lengths range from 200 mm to 2000 mm; however, longer strokes can be customized to meet

 specific application needs, effectively overcoming the stroke limitations inherent in traditional pneumatic

 cylinders.

**Low-Noise Operation**

Thanks to an optimized synchronous belt tensioning structure and vibration-damping design, noise levels 

remain below 65 dB even during high-speed operation, contributing to a more comfortable working environ

ment.

✅ Selection Guidelines & Important Considerations

**Load Matching:** The rated load capacity for the FSKT-65 typically ranges from 5 to 20 kg. Exceeding this 

limit will negatively impact both speed and service life; therefore, it is recommended to maintain a safety 

margin of 20%. Lubrication Maintenance: Regular lubrication and maintenance of the guide rails and synch

ronous belts can significantly enhance durability.

Control Integration: Requires pairing with a servo drive and motion controller; pulse-based or bus-based 

control methods (e.g., EtherCAT) are recommended.

Environmental Suitability: Although it offers semi-protective capabilities, it is not suitable for high-pressure

 washdown or continuously damp environments; external protective covers may be installed if necessary.
