The new Camozzi series 23 pneumatic cylinder with self-adjusting cushioning is built on new advances in 'self-adjusting cushioning' and complies with ISO 6432. The cylinder adjusts its cushioning automatically for optimum deceleration in all conditions.
Throughout the cushioning phase the cylinder moves smoothly, without impact, reducing vibration and noise while ensuring greater reliability and constant performance over time.
Because no manual adjustment is needed, commissioning time is reduced. The cylinders are suitable for many industrial applications, particularly where working conditions change over time through variations in size or through wear from other machine equipment.

1. The self-adjusting cushioning system of the pneumatic cylinder
The "self-adjusting cushioning" system is based on profiled sleeves with a number of precisely positioned and precisely sized holes, allowing the system to adapt to different combinations of speed and applied mass.

- Advantages
- Reduced commissioning time
- Reduced vibration and noise
- Constant performance over time
- Protection against counterfeit and imitation products
2. How the Camozzi series 23 pneumatic cylinder with self-adjusting cushioning works
During the free movement phase, the air in chamber (A) passes through seal (B) and escapes through outlet (C).
When sleeve (D) reaches seal (B), the air in chamber (A) is forced through holes (E) in the sleeve, which starts the deceleration.
As piston (F) moves, holes (E) close one after another, reducing the air flow from chamber (A) towards outlet (C) and producing a gradual, smooth deceleration.
Movement stops when the end-of-stroke position is reached and piston (F) touches end cap (G). A regulating valve (H) absorbs all remaining forces and minimises the impact so there is no vibration or noise.

The position and size of the holes have been calculated to:
- Optimise the cushioning capacity of the cylinder.
- Eliminate piston jolts completely.
- Reduce vibration.
- Reach the end-of-stroke position with minimal residual force.
