Always verify your mounting brackets and structural supports can handle calculated peak forces with appropriate safety factors.\n\n### How does air pressure affect impact force?\n\n**Higher air pressure increases both cylinder velocity and thrust force, resulting in exponentially greater impact forces.** Doubling pressure from 3 to 6 bar can increase impact force by 300-400% if velocity isn’t controlled. Consider using pressure regulators to reduce operating pressure during high-speed movements, then increase pressure only when force is needed.\n\n### Can I use the same formula for rodless cylinders?\n\n**Yes, the impact force formula**F=m×v22×dF = \\frac{m \\times v^{2}}{2 \\times d}**applies equally to rodless cylinders, rod cylinders, and guided actuators.** However, rodless cylinders often have advantages in impact management—their compact design allows for longer cushion zones relative to stroke length, and the absence of an external rod eliminates rod buckling concerns under high impact loads.\n\n### Why do my cylinders fail even with cushioning?\n\n**Cushioning failure typically results from improper adjustment, worn cushion seals, or cushions undersized for the application.** Cushion needles should be adjusted with the actual load attached—not on an empty cylinder. At Bepto, we provide detailed cushion adjustment procedures with every cylinder, and our replacement cushion seal kits are readily available for quick maintenance.\n\n### How often should I recalculate impact forces?\n\n**Recalculate impact forces whenever you change payload mass, operating pressure, cycle speed, or cushioning settings.** Also reassess if you notice increased noise, vibration, or visible damage to mounting hardware. We offer free impact force calculation assistance for all Bepto customers—just send us your application parameters and we’ll verify your setup is optimized for safety and longevity.\n\n1.
