Explore the future of pneumatics. Our blog offers expert insights, technical guides, and industry trends to help you innovate and optimize your automation systems.
Buna-N seals offer excellent performance and cost-effectiveness for standard pneumatic applications up to 80°C with good chemical resistance, while Viton seals provide superior high-temperature performance up to 200°C and exceptional chemical resistance but at 3-5x higher cost, making material selection critical for optimizing both performance and economics.
Magnetically coupled rodless cylinders offer leak-free operation and smooth movement for light-duty applications up to 500N, while mechanically coupled systems provide higher force capacity up to 5000N with direct mechanical connection, making the choice dependent on force requirements, environmental conditions, and maintenance priorities.
Air compressibility affects pneumatic cylinder control by creating spring-like behavior that causes positioning inaccuracy, velocity variations, pressure oscillations, and reduced stiffness, with effects becoming more pronounced at higher pressures, longer air lines, and faster movements, requiring careful system design and often servo-pneumatic or rodless cylinder solutions for precise control.
Pneumatic cylinder piston velocity is calculated using the formula V = Q/(A × η), where V is velocity (m/s), Q is air flow rate (m³/s), A is effective piston area (m²), and η is volumetric efficiency (typically 0.85-0.95), with port size directly affecting achievable flow rates and maximum velocities through pressure drop calculations.
Cylinder mounting type directly determines load capacity, with fixed mounts handling up to 15,000N axial loads, pivot mounts supporting 8,000N with side loading capability, trunnion mounts managing 12,000N in compact spaces, and flange mounts providing 20,000N+ capacity for heavy-duty applications, making proper selection critical for preventing costly failures and maximizing system reliability.
