High precision Positioning EG Series Guide Rod Electric Cylinders Long life

Product Specification

• Superior Rigidity and Lateral Load Resistance: Adopts a design of dual precision guide rods and recirculating ball bearing guide rails, with lateral load resistance 5-10 times higher than ordinary electric cylinders, ensuring stable operation under heavy-load or cantilever working conditions. For example, the EG32 model has a lateral displacement of ≤0.02mm under a vertical load of 24kg, far exceeding industry standards.
• 
  
• Micron-Level Positioning Accuracy: Equipped with a ball screw drive and high-precision encoder feedback, the repeat positioning accuracy reaches ±0.02mm. Some models can achieve an extreme accuracy of ±0.003mm through closed-loop control, meeting the needs of precision assembly and optical inspection.
• Modular Design and Flexible Integration: Supports multiple installation methods (flange, trunnion, through-hole) and motor interfaces (servo/stepper motors) for quick integration into production lines. The modular structure allows customizable stroke (25-840mm), speed (up to 1.48m/s), and protection class (IP40/IP65 optional) to adapt to diverse applications.
• Low Maintenance and Long Service Life: Features a fully enclosed dust-proof design combined with a lifetime lubrication system, extending the maintenance cycle to over 5,000 km. Key components (e.g., screws, guide rails) are made of high-alloy steel, with a service life of up to 20,000 hours after hardening treatment, significantly reducing downtime costs.
• High Efficiency, Energy Saving, and Intelligent Control: 60% more energy-efficient than pneumatic systems with no risk of oil leakage. Supports communication protocols such as EtherCAT and Modbus, enabling three-mode switching (force control, position control, speed control) via PLC or host computer to meet flexible production needs.

• Automotive Manufacturing: The EG46 model achieves gapless press-fitting of engine blocks with high-precision positioning (±0.01mm); the dual guide rod structure ensures stable frequent start-stop of welding fixtures, reducing welding spatter rates.
• 3C Electronics: The EG32 model, combined with vision systems, controls the embedding accuracy of mobile phone camera lenses to ±0.005mm, increasing yield rates to over 99.5%; its high speed (1.2m/s) and responsiveness meet the rhythm requirements of continuous cutting of lithium battery pole pieces.
• Medical Equipment: Joint drives for surgical robots feature low noise (≤65dB) and high dynamic response (acceleration 20m/s²), ensuring operational precision and patient comfort; rehabilitation equipment with programmable force control modes simulates different resistance environments to support personalized rehabilitation.
• New Energy Field: Real-time adjustment of photovoltaic panel orientation via angle closed-loop control increases power generation by 15%-20%; lithium battery liquid injection machines, with high-precision flow control (±1%) and anti-dripping design, ensure consistent electrolyte injection.
