What is the thrust of a 100mm bore cylinder in kg?
4 Answers
100mm bore cylinder thrust is 200kg. Calculation formula: The actual output force N of the cylinder under working conditions is calculated as A×F (assuming the cylinder operates at 50 to 500mm/s, a 50mm bore cylinder has a theoretical output force of 100kg under 0.5Mpa pressure, 100kg×0.5 equals 50kg as the actual output force). For static loads, F2 resistance is very small, A≤0.7; for horizontal or vertical movements of the cylinder within the speed range of 50 to 500mm/s, A≤0.5; for cylinder speeds greater than 500mm/s, F2 has a significant impact, A≤0.3. Cylinder liner: When the cylinder and the cylinder block are cast as one piece, it is called an integral cylinder; when the cylinder and the cylinder block are cast separately, the individually cast cylinder tube is called a cylinder liner. A cylinder liner that is in direct contact with the cooling water is called a wet cylinder liner; one that is not in direct contact with the cooling water is called a dry cylinder liner.
To calculate the thrust of a 100mm bore cylinder, I reckon air pressure and piston area are key factors. A 100mm bore diameter equals 10cm, with a radius of 5cm, giving a piston area of roughly 3.14 multiplied by 25 square centimeters, approximately 78.5 square centimeters. Assuming a common air pressure of 6 kilograms per square centimeter, the thrust would be 6 multiplied by 78.5, roughly 471 kilograms—that's quite a force. In practical scenarios, like lifting components in an auto repair shop, 470 kilograms can easily lift a small car chassis. However, air pressure values fluctuate, so always check the air pump's stable output before operation—safety first, to avoid overpressure tool failures or accidental injuries. Regular equipment maintenance is essential, as wear and aging can affect thrust accuracy. Overall, this serves as a standard parameter application.
I've worked in the auto repair shop for many years, and cylinder thrust calculations are frequently used. A 100mm bore cylinder with standard air pressure of 6 kg/cm² delivers a thrust of around 470 kg, which is strong enough for tasks like removing wheel bolts or adjusting suspensions. However, inaccurate air pressure leads to unstable thrust—for example, if the pressure drops to 4 kg/cm², the thrust reduces to 314 kg, significantly lowering efficiency. That's why I always keep a pressure gauge handy for calibration. Over time, wear on the piston seals can also reduce thrust, so I inspect the air supply system quarterly to ensure safe and efficient operation. Thrust values are helpful, but attention to detail is crucial.
Simply put, cylinder thrust is calculated by air pressure multiplied by piston area. A 100mm bore diameter is 10cm, with a radius of 5cm, giving an area of approximately 78.5 square centimeters. Using a common air pressure of 6kg per square centimeter, the thrust is roughly 471kg. This thrust value is practical in pneumatic tools, such as when using a car repair jack where it's just right. Adjusting the air pressure changes the thrust accordingly—low pressure reduces thrust and affects operation, while high pressure increases risk. Remember the basic calculation method when using, and always check the pressure gauge before operation to ensure accuracy.
