VFGD Series: The Ultimate Solution for High-Force Holding & Clamping


The VFGD series is a specialized heavy-duty pneumatic cylinder designed for "holding" and "clamping" tasks that require immense force and absolute stability. Engineered with a robust internal mechanism and high-torque jaws, the VFGD series is the definitive choice for handling large, heavy, or oddly shaped workpieces in automated production environments.

Key Technical Features & Engineering Highlights

  • Massive Clamping Force: The VFGD utilizes a specialized high-leverage or toggle mechanism to convert pneumatic pressure into massive clamping torque, ensuring workpieces are held securely even under high vibration or lateral loads.

  • Robust & Durable Construction: Built with a reinforced aluminum alloy body and high-strength steel components, this cylinder is designed to withstand the rigors of heavy industrial use and high-frequency cycles.

  • Specialized Jaw Design: The "Holding" (抱具) style jaws are often customizable or feature anti-slip surfaces, making them ideal for gripping cylindrical, round, or large-surface-area materials like glass, pipes, or metal sheets.

  • Stable & Synchronized Motion: High-precision internal guides ensure that the clamping jaws move with perfect synchronization, providing a balanced grip that prevents workpiece deformation or slippage.

  • Magnetic Sensing Integration: The body includes integrated slots for flush-mounted magnetic sensors (auto-switches), allowing for precise "Clamped" and "Released" state monitoring for PLC integration.
