High Efficiency Intelligent Dust Proof EG Series Guide Rod Electric Cylinders Precision Equipment
I. Product Overview
The EG series guide rod electric cylinders are high-performance linear drive devices, featuring a composite structure of ball screws and dual guide rods. This design delivers high-precision positioning, strong lateral load resistance, and long service life, enabling full replacement of traditional pneumatic and hydraulic cylinders. They stably adapt to fields with strict requirements for stability and precision, including automotive manufacturing, 3C electronics, and medical equipment.
II. Core Advantages
High Rigidity & Strong Lateral Load Resistance: Adopting a design of dual precision guide rods and recirculating ball guide rails, their lateral load resistance is 5-10 times higher than ordinary electric cylinders. They maintain stable operation even in heavy-load or cantilever operation scenarios. For example, the EG32 model exhibits lateral displacement ≤ 0.02mm under a vertical load of 24kg, with performance far exceeding industry standards.
Micron-Level Positioning Accuracy: Leveraging a ball screw transmission mechanism and high-precision encoder feedback, the repeat positioning error is ≤ 0.02mm. With closed-loop control (available on select models), the error can be reduced to as low as 0.003mm, easily meeting the needs of high-precision scenarios such as precision assembly and optical inspection.
Modular Structure for Easy Integration: Supporting diverse mounting configurations (flange, trunnion, through-hole, etc.) and compatible with servo and stepper motors, they can quickly integrate into production lines. Customizable parameters include stroke (25-840mm), speed (up to 1.48m/s), and protection class (IP40/IP65 optional), adapting to diverse application needs.
Low Maintenance Requirements & Long Service Life: A fully enclosed dust-proof structure combined with a lifetime maintenance-free lubrication system extends the maintenance cycle to over 5,000km. Key components are made of high-alloy steel with hardening treatment, achieving a service life of 20,000 hours and significantly reducing downtime and maintenance costs.
Energy Efficiency & Intelligent Control: They are 60% more energy-efficient than pneumatic systems, with no risk of oil leakage. Supporting communication protocols such as EtherCAT and Modbus, they enable switching between three modes (force control, position control, and speed control) via PLC or computer, flexibly meeting production requirements.
III. Application Scenarios
Automotive Manufacturing: Achieves seamless press-fitting of engine blocks and cylinder heads with ±0.01mm positioning accuracy. The dual guide rod structure ensures stable operation of welding fixtures during high-frequency start-stop, reducing the welding spatter rate.
3C Electronics: When paired with vision inspection systems, the EG32 model controls the assembly error of mobile phone camera lenses to ≤ 0.005mm, with product yield exceeding 99.5%. Its high speed of 1.2m/s and rapid response meet the rhythm requirements of continuous cutting of lithium battery pole pieces.
Medical Equipment: For joint drive in surgical robots, it features noise ≤ 65dB and acceleration of 20m/s², balancing operational precision and patient comfort. Rehabilitation equipment adjusts resistance via program settings to support personalized rehabilitation training.
New Energy Sector: Real-time adjustment of solar panel orientation through automatic angle closed-loop adjustment increases power generation by 15%-20%. When used in lithium battery liquid injection machines, it offers flow control accuracy of ±1% and an anti-dripping function, ensuring consistency of electrolyte injection.
