What function do cylinder cushions serve in a hydraulic system?

Cylinder cushions play a critical role in enhancing the performance and longevity of hydraulic cylinders by dampening the end of the cylinder stroke. When a hydraulic cylinder reaches the end of its stroke, the sudden stopping can create significant impact forces that may lead to wear, damage, or even failure of the cylinder and its associated components. Cylinder cushions provide a cushioning effect by using a small reservoir of hydraulic fluid, allowing for a gradual deceleration of the piston as it approaches the end of the stroke. This softens the impact, protecting the mechanical parts and improving system reliability.

In addition to safeguarding components, the cushioning effect improves operational safety and comfort, as it helps to reduce noise and vibrations during the movement of the cylinder. Properly adjusted cylinder cushions ensure that the hydraulic system operates efficiently and extends the service life of the equipment.
