FAQ
Q: Can LIND heavy-duty rotary electric cylinders directly replace hydraulic rotary actuators?
A: Yes, absolutely. LIND heavy-duty rotary electric cylinders can deliver equivalent or higher torque outputs (up to 50,000 Nm). By custom-matching the mechanical mounting interface (flange, shaft, or keyway) to your existing equipment, they seamlessly replace hydraulic cylinders. This upgrade eliminates oil leak risks, reduces energy costs by over 40%, and provides precise, programmable motion control.
Q: How does the rotary electric cylinder maintain high precision and back-lash control under heavy, high-impact industrial loads?
A: We utilize high-rigidity alloy steel internal gears (precision ground) and oversized, heavy-duty tapered roller bearings to absorb massive axial and radial dynamic shock loads. Combined with a high-resolution absolute encoder on the servo motor, the system maintains a closed-loop repeatability of +/- 0.01 Degree to +/- 0.05 Degree even in harsh, continuous-vibration environments.
Q: Do your drive systems support customized industrial voltage and communication protocols for different global regions?
A: Yes. We support global industrial power supplies, including AC 220V, 380V, 400V, and 480V at 50/60Hz. For seamless integration into your existing PLC architecture, our drive systems are fully compatible with major industrial bus protocols such as EtherCAT, PROFINET, EtherNet/IP, Modbus TCP, and CANopen.
Q: What is your standard lead time for customized heavy-duty rotary cylinders, and how do you ensure transparency?
A: Standard models usually take 3-4 weeks. For fully customized engineering solutions (including 3D design sign-off, specialized machining, and FAT testing), the lead time is typically 6-8 weeks. To ensure full transparency, our export team provides weekly progress updates, including actual photos and video clips from our factory floor.
Q: Can you provide 3D CAD models (STEP / IGS files) for mechanical design verification before placing an order?
A: Yes. We welcome engineering consultations. Once you share your basic application requirements (torque, speed, rotation angle, and space constraints), our engineering team will generate and provide the 3D CAD models (.STEP or .IGS) so you can integrate them into your assembly drawings for fitment verification.
