Sizing Bernoulli Grippers: Avoiding Drops, Flutter, and Air Supply Pitfalls
How do you lift fragile glass, porous cloth, or delicate circuit boards without touching them or leaving marks? In this episode, we unpack the mechanics and engineering formulas behind SMC's ZNC Bernoulli gripper series. Discover how high-velocity compressed air creates a localized low-pressure zone to hover and lift workpieces without a vacuum seal. What you'll learn in this episode: The Core Physics & Advantages: Why Bernoulli grippers succeed on porous, thin, or mark-sensitive materials where traditional suction cups fail. SMC's Selection Formula (W = M × g × t / n): A step-by-step breakdown of how to calculate the required lifting force per gripper. Why the Safety Factor Matters: Why SMC recommends a minimum safety factor (t ≥ 2) to handle acceleration, shock, vibration, and wind pressure during move profiles. Attachments & Curve Adjustments: How stoppers and vibration suppression covers affect lifting distance and force, requiring curve readings at 1 mm or 1.5 mm instead of rated catalog values. Real-World Engineering Trade-Offs: Managing heavy air consumption (131–255 L/min per gripper at 0.5 MPa), selecting body materials (aluminum, resin, or stainless steel), and why external guides are essential to prevent horizontal sliding. Whether you're designing end-of-arm tooling for cleanrooms, electronics assembly, or high-speed pick-and-place systems, this episode gives you the practical math and guidelines you need to size your application correctly.
