The Advantages of Pneumatic Cylinder Cushioning

Why is pneumatic cylinder cushioning necessary?

Some form of cushioning is normally required to reduce the rate of travel of a cylinder before the piston strikes the end cover. Reducing the piston velocity at the end of its travel lowers the stresses on the cylinder, while reducing vibration in the structure of which it forms part. Efficient cushioning is usually necessary in applications where precision is a must.

This problem can be solved in one of three ways – by means of simple impact cushioning, by pneumatic cushioning or by fitting shock absorbers. The PDF document below deals mainly with pneumatic cushioning and is intended to serve as an instruction on how to achieve ideal cushioning; in other words, how to optimise the degree of cushioning for a given mass.
