Under what condition should you use cylinder cushions?

Using cylinder cushions is essential when there is a risk of the piston striking the end of the cylinder due to the load. Cylinder cushions are designed to absorb the impact of the piston at the end of the cylinder's stroke, thereby preventing damage to the cylinder and the load itself. This cushioning effect is achieved through a controlled deceleration of the piston during the last few millimeters of travel, which helps to minimize shock loads that can lead to wear or failure of the hydraulic system components. Implementing cylinder cushions in these scenarios ensures better longevity and reliability of the machinery, especially in applications where heavy loads might cause violent impacts.

The other conditions listed do not directly relate to the primary function of cylinder cushions. For instance, while high pressure and quick stops can influence hydraulic performance, they do not specifically necessitate the use of cushions for protection against impact. Similarly, the temperature of the hydraulic fluid does affect system performance, but it is not a determining factor for the need for cylinder cushions.
