What is the purpose of pneumatic cushioning in a cylinder?

Pneumatic cushioning serves the specific purpose of slowing down cylinder motion at the end of the stroke. As a cylinder approaches the end of its travel, the use of pneumatic cushioning allows for a gradual deceleration, effectively reducing the impact that occurs when the piston reaches its limit. This controlled slowdown minimizes the forces acting on the cylinder and its components, thereby preventing abrupt stops that could cause damage or excessive wear. The cushioning effect is achieved through a mechanism that allows air to escape slowly, creating a softer landing for the piston within the cylinder.

While pneumatic cushioning can indirectly contribute to reduced wear and enhance energy efficiency by promoting smoother operations, its primary role is to ensure safe and controlled stopping of the cylinder. The advantage of utilizing this technology lies not only in extending the lifespan of the cylinder components but also in improving the overall performance and reliability of the pneumatic system.
